This microwave oven is a remarkable feat of Engineering.
The rapid heating that makes microwaves popular is made possible by power provided from this vacuum tube.
It’s likely in a radio like this inevitably tiny transistors, and microchips replace clunky vacuum tubes,
but it’s too soon to relegate them to the museum microchips can’t easily replace tubes for producing power.
Heating food now a microwave contains three main components.
A vacuum tube called a magnetron it generates the energy that heats food a waveguide hidden in the wall to direct that
energy to the food and a chamber to hold the food and safely contain the microwave radiation.
In principle, a microwave oven heats no differently than any other type of heat transfer at a molecular level.
Heat is a transfer of energy that results in increased motion of the molecules of the substance.
Since we aren’t quantum sized, we observe this increase in movement as a rise in temperature in a traditional oven or stove.
We heat food by placing a pan on a burner or in the oven where the walls radiate heat which cooks the outside of the food.
The insides cook wood heat transfers from the surface of the food to its interior in contrast energy from the magnetron penetrates into the food.
Which means the whole mass of food can be cooked simultaneously.
How does it do this?
Well, our food is filled with water which is positively charged at 1:00 in and negative at the other to give these molecules more energy.
We expose it to electromagnetic waves that emanate from the tube by definition the waves have the electrical and magnetic fields.
That change direction rapidly for this oven the direction of the areas change 2.45 billion times per second.
Water will try to align with the radiations electric field.
The changing field rocks the water molecules back and forth rapidly.
Molecular friction from this creates heat as the motion disrupts the hydrogen bonds between neighboring water molecules.
Now you can get an idea of the wavelength of the energy emitted from the magnetron using cheese.
If you can see carefully than you observe, where the cheese is completely melted in other sections.
Where it’s completely unheated, the ovens metal walls only reflect waves of a link that fits inside the oven.
This standing wave causes hot and cold spots inside the oven.
The three-dimensional pattern of ways it’s difficult to predict, but the principle can be seen by looking at the waves in a single dimension.
The peaks and valleys in the wave represent the most significant energy of the stream, while the nodes here correspond to the cold spots inside the chamber.
If you measure the distance between melted cheese spots,
you will find about two and a half inches that would be half the wavelength the distance between nodes and is pretty close
to the actual wavelength of microwave radiation used.
Using that wavelength, you can estimate the microwave radiations frequency the frequency is related to the wavelength by the speed of light.
I get an answer that only has a four or five percent error not unfortunate for this first measurement now the real engineering.

In the microwave oven lies in creating the magnetron that generates high-powered radio waves it’s honestly an amazing
and revolutionary device the vacuum tube is inside here these are cooling fins thin pieces of metal that dissipate the heat.
As the magnetron operates the essential parts are these two magnets and the vacuum tube.
Apply a large voltage across both the inner filament and the circular copper.
Microwave Oven Repairs in Faridabad
Outside this voltage boils electrons off the center filament and they fly toward the circular copper section.
The thread is made from tungsten and thorium tungsten because it can withstand high temperatures and thorium
because it’s a good source of electrons the magnets Bend.
These electrons that they swing back toward the center filament.
We adjust the magnetic strength so that the now orbiting electrons just rush past the opening of these cavities like
blowing over a half-filled pop bottle to make it whistle this creates an oscillating wave.
The microwave radiation that food it’s just astonishing that these cavities can be produced with high-precision low-cost
and incredibly high reliability.
Microwave Oven Troubleshooting in MINUTES ~ STEP BY STEP
okay in this Blog I’m going to show you in a step-by-step fashion how to
troubleshoot your faulty microwave oven now before we start I’m going to go over
a few things that you will need to carry out this troubleshooting procedure
you’re going to need a good digital multimeter you can use analogs one as
well but I prefer a digital you’re also going to need a couple of jumper wires
you can get these at RadioShack or any other electronic supply store they’re
relatively inexpensive you’re also going to need a Phillips and slot screwdriver
you’re also going to need a twenty K ohm ceramic resistor like this it could be a
watt a watt or even higher if you cannot find a K ohm resistor at your
electronics supply store then you could always look for a lower value all the
way down to a k with work but make sure it has a sufficient wattage so try and
look for a ceramic one you can also look in old electronics old television sets
and stereo equipment and they also look like this that’s a ceramic resistor so you could
look for one of these and you can just pull it out of the old equipment and use
that a lot of microwave ovens use a tamper proof Torx screw on the cabinet
to open it so have a tamper proof Torx bit just like these is a hole in the
middle you can also get by with a tamper proof hex key you can find this at your
local hardware store or Home Depot or Lowe’s ok so let me go over a few of the
problems I fixed many of these over the years probably at least of them my
friends have brought me microwave ovens I’ve repaired them for work so I’ll go
over a few things that are very common one issue might be there’s no power to
the microwave at all and you did verify that your receptacle has power by
plugging in another appliance or a lamp just to make sure there is power
another problem could be that when you turn on the microwave the light comes on
the turntable spins but you do not hear the hum of the transformer for the
magnetron so that could be another issue you could have another problem food
isn’t getting hot enough you can also have a problem that when you go to push
start on the microwave oven that the breaker trips so there’s a few different
problems I’m gonna go over each one now the first thing you going to want to do
is make sure the microwave oven has been unplugged then you’re going to want to
remove the cover on the microwave oven generally a lot of microwave ovens will
have a screw here and there and the same on the other side as well as on the back
where it’s bent over one there and along the top there’s going to be one or two and the
same screw here on the opposite side okay once the screws have been
removed from the cover gently grab the sides and you’re going to slide it we
tilt it up a little outward like that when you put it back you’re going to
slide the front edge in and tilt it down okay the cover has been removed and on
one side of the microwave closest to the control panel which is right here you’re
going to have all the components right in front of you now before we touch
anything or do anything in the microwave the first thing you’re going to want to
do is discharge this capacitor right here it’s an oval capacitor it’s a ,
volt capacitor now even though there is an internal resistor bleeding off the
voltage when powers removed it’s still a very good idea to make sure
there is no voltage there because it could be deadly now you’re going to take
the resistor clip one onto the screwdriver make sure it’s on there good
the other end is going to go to the ground screw on the chassis or any other
bare metal part that you can find once that’s connected to the screwdriver
like so you’re going to reach down to the capacitor right there and you’re
going to touch it to each term and I’ll just hold it there for about seconds
once you do that terminal you’re going to reach into the other boot right damn
touching the other metal terminal and hold it to that one remove the
screwdriver now just to make sure it is fully discharged take the end of the
wire don’t touch the clamp push it against the terminal reach into the
other boot hold it there a few seconds and remove it now it’s
also a very good idea to take an insulated pair of needlenose and once
you’ve done all this to go between the two and wiggle that around if you get a
loud spark you didn’t do a good job so there should be no spark between the
terminals this is now discharged now you can safely work inside the unit now I’m
going to point out all the locations of the components this is your cooling fan
you have your capacitor right here right next to the capacitor is zoom in right
here this little black cylinder that’s your diode high voltage diode we’ll be testing that you have your high voltage
transformer right here this is the magnetron that produces the microwaves
over here on the left side you have your
PC the PC board low voltage transformer you have your circuit board
you have the relay located on the circuit board on
the other side of this piece of metal there’s going to be two or three switches lined up that look like this
this is what the switches look like for the door little button on each end
when you push it in and out it makes the
connection between the two blades go on and off and between these
two blades go on and off now right over here this is
the light it shines through the screen now on a lot of microwave ovens you’re going to find that there is a little
board here where the power supply comes in and on
that board will be a filter like this and a ceramic fuse now that
fuses a amps low blow fuse it’s ceramic now if your microwave is not working at all
you have no power display
or anything else you may just want to swap that fuse out
because it may have just gotten worn out over time so if you
change that fuse and you notice there’s no problems for a little while
and you’re good to go but generally when
that fuse blows is a problem now on this unit you can see the fuse is in a holder
right here you would just pop the fuse
holder open and check the fuse right in there now if the
microwave oven is powered up and you have the digital
display going and you open the door and light comes on but the microwave will not turn on then you could have a
problem with one of your switches which I pointed out earlier
which is this right here what these switches do is
they tells the circuit board that the door is fully closed and
if the door is not fully closed the microwave will not
power on now the way to test the switches is very simple
you’re going to use a continuity setting on your digital
multimeter or a very low ohm resistance setting the next step
you’re going to look at the switch and you’re going to
see the wires connecting to the switch you’re going to touch one probe of your connector to one lead
and the other to that one like so and then you push the button and that verifies the switch is working
do it to all the switches you can find is usually two or three now
some of them when you connect it up like you see here
the alarm will already be on and when you push the button in it will go off that there’s two different types of
switches normally open and normally closed now
you’re only going to test the blades that have the wires attached to
it if you have a switch like this that has three and only two wires are on the switch
don’t bother checking the one that’s not connected to anything now
many microwave ovens have the power supply feeding
through one or two thermal cutoff switches like that with that’s designed to do is that this gets too hot inside
the microwave oven this circuit opens up and these need to be replaced the other way to test them
is the same way as the switch I just showed you you’re going to put the continuity tester across both of the
terminals like this lay one there and this should have continuity when you touch it that’s a good one
if you touch it and it doesn’t go on you know you have one that blew you need to replace that you
if the fuse is good the thermal cutoff is good and all of
your door switches are good you should have full power to
the microwave oven if you don’t the next step is to make sure all of the blade
connectors attached to the switches and
the thermal cutoff like this make sure they’re plugged in good and then
you’re going to have to suspect that your low
voltage transformer on the circuit board which is right here that
that is faulty if this display does not come on you can
refer to my other Blog and shows you in detail how to test this part right here if you feel yours is faulty the link you
can click is right here now if you turn on the microwave the light comes on the
turntable is turning but you do not hear
the hum coming out of the microwave oven then it is a few things that can cause the problem
now right on the back of the circuit board is our UA which looks exactly
like this once it’s removed this is what the
relay looks like you have three pins that go into the circuit board
that are soldered in you got two blades sticking
up this is what the relay looks like when it’s removed and
I’ve seen many times that when the microwave is running
with the light on and the turntable is moving and you don’t hear
the transformer humming that the contacts
inside the relay have arced and they no longer make a good contact
so what you’re going to do to check to make sure
this isn’t faulty is you’re going to make sure everything is put back together in microwave that you took
apart if you took anything apart you’re going to put a cup of water in there and
you’re going to power the microwave up
with the cover off and then while the microwave is running and
you don’t hear the hum and nothing’s getting hot gently
take your screwdriver and just tap like this keep tapping
the relay don’t bang it too hard just keep tapping it now
when you’re tapping it like this if you hear the hum come on
and the light dim then you’re going to know the magnetron
right here is now active because you’re getting power feeding into the primary side of the high voltage
transformer and that would indicate you have bad contacts in your relay you would then have to desolder the relay
from the circuit board and install a new one like this to -volt relay okay
so once you’ve established that tapping on
the relay does not cause the transformer to be powered up to turn
on the magnetron you should hear a hum when
it’s running if you don’t hear a hum is not running right then the
next step is to disconnect the power and discharge
the capacitor once again once the capacitor has been discharged
you’re going to take your digital multimeter on
the high voltage AC setting connect up on your alligator clips to one of the probes reach in with the other end clamp
it onto the blade terminal of the primary side which is the wires coming from the board
you don’t want to touch
these wires that are red stay away from these anything go into the capacitor
those are all high-voltage take the
other probe on the AC high voltage setting and you’re going to take that and connect that to the other side of
the transformer and now you’re going to plug the microwave oven back in again
and don’t touch anything next you’re
going to want to put the cup of water in the microwave and repeat the procedure
as before just like you’re going to cook
something and as soon as you push start you’re going to want to look at this
right here make sure you see volts being fed
into the transformer if you see and you still don’t hear the hum then we can move forward if you don’t see then
that’s going to indicate that there’s definitely an issue with the relay mounted on the circuit board you want to
correct that before anything else more than likely once you correct that
everything will work fine now if you do
see volts at the blade terminals on
the primary side of the transformer which is the real heavy wires wound then
we can move to the next step so you see volts on these terminals as the
microwave is running but you still do not hear the hum the next step is to turn off the
microwave oven and unplug it and discharge the capacitor once again once
the capacitor has been discharged and the plug has been removed you can remove this connector
from here like that you’re going to take a piece of masking
tape and you’re going to notice that the diode is connected to one blade
which is this wire and the other blade goes into a different spot on the transformer
just make sure you tape together the diode with the wire that’s on the same blade
now to release the top connector you have to push down with a small pointed tool like this in the blade connector
and pull and it will release once you release the blade connector I want you to refer to my other Blog it’s in the
link you see right here next to this link you’ll see a number that is the position in the Blog where you can jump
to to see just the testing for this transformer if the transformer passes the test all right so the next step now
would be to check out the magnetron is a Phillips screw holding
one-sided unscrew that okay so you remove the screw
holding in the magnetron it might be a little bit of a clip so just rotate it a bit and pull it out now once you take
out the magnetron inspect the magnets these donut magnets right here make sure
they’re not correct check all the way
around shake it make sure there’s no rattling check the end make sure nothing’s cracked so that looks good now
the way to test this go to your low setting on your meter in this case mine goes down to connect one probe to
one terminal the other to the other terminal and you should have a very very low reading like
you see here you don’t want to dead short you don’t want to see three zeros but you want to see anywhere from point
one to point three in that range that’s a good one the next test of the magnetron is to
raise your setting to the highest that you have for resistance I’ll put mine to a twenty Meg I have , Meg’s but put
it to and what you want to do is you want to check let the meter go up and fly you want to check between each pin
of the magnetron – the body itself you should see no reading show up on this meter alright nothing if you see
something happening it’s not a good sign check that one oK we’ve established that
the magnetron is good now on to the next step okay the magnetron is all back in since
we’ve verified that’s okay the transformer you verified from my other Blog that’s okay
make sure the connector goes back in the same way you took it out this wire here goes with the diode so that’s going to
leave us two things to check out now we’re going to check out the capacitor and the diode now usually when a
capacitor is bad when you go to hit power on you will experience a short-circuit blowing the fuse or the
circuit breaker and if your diode is not proper if your diode is not working good you’re not going to have good heating of
the food and you also may have a louder noise coming from the magnetron a different sound like a different hum
then you want to check that out so we’re going to check out the capacitor first and simple to check
okay so now you want to remove the clip the clamp holding down the diode and the capacitor the diode can only go in one
way it’s got a ring connector here and a blade connector here so reach down okay
that’s that and the screw is right here
nice to have a magnetized screwdriver you’ll see the line on
the diode goes to the chassis open up this a little bit
lift up and pull the capacitor out back away a little bit all right
so there’s a capacitor okay so to test the capacitor
is very simple once you remove it and you know for a fact it’s been discharged
just double check by touching the terminals together all right put your meter on M setting
one probe with the meter goes to one terminal and the other
probe goes the other terminal now when I connect it you want to
see a high reading like in the millions like five
million and you want to see it slowly go higher and higher and higher like
two ten million that would indicate a good
capacitor four million five million six seven as long as it does that you’re good you don’t want a low reading if you
get anything that stays where you connect it or moves lower that’s a problem
the next test to verify if this is any good leave one terminal connected and take
the other terminal on the Meg’s setting or if you have it and
connect it to the can you want to make sure there’s no connection between the
terminal and the can now let’s take this one off move it to here and you notice
no change in the meter so it’s acting
properly and there’s no connection on that range so this is good to go ruled
out the capacitor all right now the way
to test the diode is the last part the test is fairly simple if you have a meter that can go very high like
mega ohms and if you don’t have that now what you’re going to do is you’re going
to refer to the link that you see right here it’s going to take you to my microwave oven testing Blog and you’re
also going to see a number in that link which is going to open in a separate
window you won’t lose this window because that will allow you to jump to the part in the Blog
where this testing is done now if you do have a high resistance DMM
and the next step to do the next step would be to put this on a
high setting of say let me take my wires without using your hands you’re going to
take the meter and you’re going to put one on the one lead and touch this lead
one direction should go hi all right and it should level off around or mega ohms that’s fine
now when you flip it around you should get a low reading around or
so okay that’s a good one so you just
confirmed that this one is a good one this test works all the time as long as
you have a high resistance meter and that’s about it that’s all the parts
that you can check make sure all the wiring harnesses and the connectors are
plugged in properly make sure there’s no loose connections and you should have no
problem figuring out why your microwave is not working properly if any of these
tests failed or you have any loose wires you should have discovered them by now
if you have any other questions please post them in the comment section I can
assist you that way if you found this Blog helpful please rate it
and also post links to this Blog on other websites and blogs thank you
