This is a very simple repair, that usually is not expensive. The motor usually averages about $35 - $40, but the price also depends upon the model. This repair can also be performed on an over the range model microwave oven WITHOUT uninstalling it.

You can purchase replacement parts at the any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The first three sites listed offer helpful exploded view diagrams to assist you in parts location/identification. If you have any questions, please post back with your model number and let me know. I hope this helps you.

There many be an internal fuse that has blown.

To find out you will need to dismantle it, if you feel that you are skilled enough to do this.

If it is very old (old than, say, 5 years), then it might be better to replace the oven. (They deteriorate slowly and if it is old, then it may not be working as well as when it was bought).

Try your oven on another circuit in your house. It is curious that your oven doesn't blow its own fuse before the house one. If it doesn't blow the fuse in the "new" circuit, check to see what is really on the kitchen circuit. It might, in fact, be overloaded. Good luck.

It usually cost a lot to fix a cooking problem on microwave. Take it in for consult only. Compare repair price to new price before deciding. Don't ask them to come to your house. It will cost! You can get repair or replacement ins. to cover all your used appliances. Including heating and cooling. Not very expensive. Check on line.

U most definitely have a failure of the magnetron, i have no idea what this diode fix is, so suspect it is an urban legend, read many such things on fixya, in any event it is an expensive part so here is how you test the magnatron:
Testing a megnetron:
NOTE: Before you test this component, make sure your microwave is unplugged, and that you have discharged the capacitor.
There are two tests to conduct in order to determine whether or not a magnetron has become defective. If you receive results other than what are detailed below, you will have to replace your microwave's magnetron. Each test is described for you here:
TEST 1: Locate your magnetron and label each of the wires attached to it so that you know which wires are to be replaced where. Set your ohmmeter to the lowest resistance scale. Take a resistance measurement between each of the magnetron's terminals by touching each probe to one terminal each. Reverse the probes and take a second resistance measurement. Each measurement should read less than one ohm.
TEST 2: Set your ohmmeter to its highest resistance scale. Touch one of the meter's probes to a magnetron terminal. Touch the other probe to the metal magnetron housing. Take special caution to not touch the two probes together. This could result in an inaccurate reading. This test should produce a reading of infinity - indicating an open circuit.
If the magnetron is defective here is the way to replace it, the oven must be removed from any built in enclosure.
As far as replacment goes have a certified and experienced appliance repair technician examine and replace your magnetron. This task is much too dangerous for the average layman to perform on his own.

Seems like you have a bad magnetron and it may need to be replaced or you may just want to save yourself the hassle, and get a replacement. Hope that helps.

sounds like you will be needing a new turntable motor and perhaps the coupling as well.

-door inter-lock switch(s) / monitor switch
-thermal cutout
-door, triac or circuit board fault

all of these could be culprit
all of these can be tested let me know if you need further instructions.

The fuse is protecting the unit from over heating and catching on fire. Either the electrical circuitry is bad in the unit or in the outlet you are using. You can test the outlet with a voltmeter to test the outlet to see if it is good or try another similar type of appliance. Chances are, it is the microwave.

This problem is almost always due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

The shielding may keep the interference out of the controls, but it's still being emitted, and the magnetron will eventually go bad.

Details covering some previous models are in GE's bulletin here. Even if your model is not on the list, the same problem can occur.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

NOISY MAGNETRON TEST (c) 2009 William E. Miller [email protected]

One way to test it is to do the following:

1. Unplug the microwave or turn off its breaker.
2. Open the door, then detach the control panel as shown in the video at http://www.microwavedisplay.com and swing it down, but without disconnecting the wires. )If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.)
3. Plug the microwave back in.
4. Make sure neither you nor anyone else reaches in behind the control panel. There will exposed high-voltage connections.
5. Put a few cups worth of water in a microwave-safe container and place it inside the microwave.
6. Shut the door.
7. Run the microwave for about 1 minute or so on full power. (Time Cook > 1 > 0 > 0 > Start, e.g.)
8. If it does not fail, try it several more times.
9. When the water boils, change the water and try again.

NOTE: If your model does not have a door handle, you will need to unplug the oven and reattach the control panel to be able to open the door.

If it still does not fail, I would recommend that you put it all back together and keep using it until it fails more consistently, then repeat this test.

While a microwave should never be left running unattended under any circumstances (as your owner's manual will tell you) it's even more important when one is exhibiting a failure or any odd behavior. So play it safe and stay with it while it's running!

If you or someone you know want to replace the magnetron yourself, you will need to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.



At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If it's under magnetron warranty, GE will send you the magnetron to do it yourself. Call them at 888-239-6832.

hello mam please check the programmer.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Otherwise, this is almost always due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If it keeps failing while the board is in the down position, you either have a very leaky magnetron or possibly another problem.

So you can then get a Ziploc bag and insert a flat piece of aluminum foil into the Ziploc and close it.

Then (with the power off) tape it over the circuit board as best you can, covering it as much as you can, making sure it does not get snagged or punctured.

Then try the oven again. Do not leave this test shield in place as a "fix". It is not safe.

> but he would also replace the capacitor and diod when replacing the mag tube

Most of the time replacxing them all is done due to ignorance about how to actually test devices, a mistaken notion that it's somehow necessary, or to pad the bill.

The diode may be necessary in some cases (if it tests bad) but the capacitor is almost certainly not needed.

When a capacitor fails, it almost always shorts. If so, the fuse would blow when you peress "Start" to begin cooking.

I've rarely (if ever) seen one fail without shorting.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then GE manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

> Can I just replace the mag tube without also replacing the diod and capacitor?

Almost certainly.

Actually it is more realistic buying the door and glass complete. Price difference is not excessive. Removing plastic d/layer "glass" dissrupts the seal and small nitty gritty items break. Must be 100%good seal for microwave action.

you have actually shorted the switch on the control board
if you can live with out it, ok but if you cannot you will need to repalce that switch
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=217012
this is a breakdown for your u nit

oipen the control board, one screw behind the door
lift up and out

inspect the control for any obvious signs of burn,

here is where it gets a little triccky, your voltage issue has to be traced
between the control board and the membrane.....

9-10 times the membrane is what goes, if not the motor,
is just has the least resistance...

with the breakdown you should be able to see how to easily replace it

hope this helps have a good day

If that doesn't work, leave it unplugged for about 5 minutes.

It could be the plastic coupler part #942560. Remove your glass tray and lift up the plastic piece in the middle. It slides off of the motor. If it is broken that is your problem.

If replacing the entire door, all that is required is to open the door all the way open and lift straight up on the hinge side of the door. The door will lift off the hinge pins. You may have to remove the upper grill cover (if equipped) on some models for better access. If you have questions, please let me know. I hope this helps you.

yes pry out with either 2 flat knives or screwdrivers. It will lift out Make sure you replace with the exact one as they are not all the same.
