Everything works on my ge jvm2070 microwave oven but it will not heat anything up
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 is required to heat 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. There are several websites that you can use that illustrate how the oven is assembled:
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 around $100.
4. Some model microwave ovens have a thermal cut-out (TCO) associated with the magentron circuit, and/or oven cavity. If these small thermostats trip, they usually render the ENTIRE oven inoperable. The lights would not work and the carousel would not turn. You will need to remove the thermostat from the oven (if equipped) and take a resistance check across the component terminals to determine if it is good or not. A low resistance reading indicates a good thermostat. An infinite reading, indicates a blown thermostat and needs to be replaced. The average replacement cost is about $10. I would recommend you check any fuses associated with the oven before assuming the magnetron has failed.
NOTE: In the model you have listed, here is a list of components you may want to check (refer to the parts diagrams listed at the websites provided):
Item 88 Magnetron part# WB27X10735
Item 90 Thermal Cut-Out part# WB27X10166*
Item 111 Thermostat part# WB27X10195*
*I would recommend checking the Magnetron TCO and Thermostat, first. These parts are fairly inexpensive and are more likely to cause the symptoms you're experiencing. If these components don't solve the problem, then you probably have a blown Magnetron.
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.
If you have any questions, please post back and let me know. I hope you find this information helpful.
