GE Microwave JVM1540LM2CS Doesn't Heat

My daughter's microwave won't heat and the turntable doesn't turn. The unit has power and all the other functions (interior light, touch pad, etc.) seem to be okay. Could it be the magnetron or do you suspect something else? Is there a way to troubleshoot it? Thanks!

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

Yes, it could be the Magnetron. If the unit is out of warranty, you can try to remove the rear cover (make sure unit is unplugged) and see if there is a blown fuse in the section that powers the Magetron. They are not too difficult to replace. MCM Electronics sells them and you can call them with your model and they can find a replacement for you will be able to see how much it will cost.

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and your magnetron is still under the part warranty, but you would have to pay labor.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

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.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/diode.html
(if it's not shorted or burned, it's probably okay)


http://www.gallawa.com/microtech/mag_test.html

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

If it's within the mag warranty, G.E. should send you the magnetron to do it yourself. Call them at 888-239-6832 with your model, serial, and manufacturing date.


If nothing else, you can save about $50-75 if you remove it from the wall and take it to a GE-authorized servicer.

You can find a GE-authorized servicer by calling GE Appliance Service at 1-800-848-7620 or here.


Accessing some components for testing and possible replacement will require you 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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

If it wil not heat it is definitely the magnetron and it is usually cheaper to buy a new microwave oven than reparing it, even if you do it you'r self

if it has a turntable does it move? Possible diode, inverter board (may have the diode on it or the Magnetron.

If an inexpensive unit it may be cheaper to replace than repair.

If the unit operates correctly except heating the food, then the unit needs a new magnetron.

Microwave turns on but no heat and turntable doesn't turn


It is one of two things, a defective door switch, "most likely" or the keypad control board is faulty.

Hello, welcome to Fixya!

The unit not powering on is an indication that it has a power fault.

First, remove the microwave's power cord from the wall, wait for about 30mins, then plug it back in. It may cool by then and might power on. If it doesn't power on, plug it into another outlet, to make sure there electricity entering into the unit.

If plugging into another power outlet doesn't power it on then the unit is most likely having a power problem.

When electric current comes from the power outlet into the microwave, it goes straight into the power supply board which then circulates the current into the unit. So if the microwave doesn't power on, the first thing is to make sure there is power entering into the machine.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

If any machine or electronics device doesn't power on, it means its having a power problem. It might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This microwave must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the microwave turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store within our vicinity.You might also find visible bad component without testing with a meter. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.
