It could be the magnatron is faulty or it could also be the highvoltage fuse is faulty, i would quote the parts at $70 and the labouar at roughly $50-$60, all depends on the unit itself.i would love to help but i live in nsw australia.but i hope what i have told helps somehow.

If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is the heart of the microwave oven and produces the RF energy that heats your food. In order to replace a defective magnetron, you will need to consider the following:

1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).



2. Ensure the oven is UNPLUGGED before servicing anything inside the cabinet and remove the exterior case in order to access the magnetron. The High Voltage circuit in these ovens produces between 3,000 and 4,000 VAC and should NOT be worked on unless you are saavy with electronics. In addition, these ovens should NEVER be turned on, or serviced with the exterior cabinet removed, interlocks defeated or high voltage network protective cover removed.
Here are several websites that you can use that illustrate how the oven is assembled:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com


Repairclinic.com is another great website for parts, and has part illustrations/photographs, but does not have the exploded view to show how the appliance is assembled.


NOTE: If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.


3. The magnetron replacement cost will depend upon the MODEL NUMBER and generally costs between $100 and $200.


Use your appliance model number and review the parts illustrations at the recommended websites to identify and locate parts, and to see if this is something that you may be able easily take apart and reassemble.


NOTE: If your appliance is still under warranty, do not attempt to repair on your own, as this will void any warranty you may still have. Most manufactures have a one year limited warranty against any manufacturer defects, but may have extended warranties on certain parts. If in doubt, contact the manufacturer to find out what is covered.


If you have any questions, please post back and let me know. I hope you find this information helpful.

Not heating


If the oven is doing everything else properly (light comes on, fan runs, turntable goes around) but there's no heat, you may have a failed magnetron tube (the microwave source). There's also a relay that controls power to the tube that may not be working correctly, or the control circuit board is bad. It's also possible one of the door switches is not working (so the oven thinks the door isn't closed), although this usually keeps the turntable and fan from running.

Microwave oven service is not for do-it-yourselfers. There are potentially deadly voltages present even with power off, and a chance of microwave leakage if repairs aren't done properly. Let a professional give an estimate to repair it, or just replace it if it's under $100. (When I was servicing these things it wasn't unusual for a repair to cost over half the price of a new one. That's one of the reasons so few shops still work on small appliances.)

My microwave will not heat. Everything else works.


hello. i can help you.

When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.

If it is under warranty you are golden. If not, you should get an estimate, as many new microwaves are now in the 50 dollar to 99 dollar range

GE JVM1640 won't heat


These microwave ovens have a series of door switches. One of yours has gone bad or a plastic finger on your door mechanism that pushes the switches is worn or broken off. They are commonly called NC or NO swithes some ovens have up to 6 of these working together.If you have no expertise in this field consult a repair shop. Please rate me
Comment posted on Jan 12, 2009 there are two types ,normally open and normally closed, NO NC . u have to check continuity on each one and each switch will have a diagram on the side showing its in use position. I hope this has been helpful

Fisrt, check to be sure your missing cat it not inside the unit. IF the interior is dirty (splatters, grease, etc.) , it may inhibit the unit from working properly.
