I would suspect a shorted high voltage rectifier diode or failed magnetron, in the order.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first: (if it is NOT shorted, it's probably fine) (continuity can be good even though it is bad!)

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also 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.

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

My GE spacemaker II microwave won't heat what can I do

The main internal component of your microwave oven is called a magnatron. This is the device which generates the microwaves that heat your food up. If your oven appears to be working properly but it's not heating the food, it means the magnatron is not generating microwaves. It could be faulty itself or it could be a component linked to the magnatron. (high voltage capacitor) etc.
Have this component checked by a qualified technician.
Let me know if I can be of any further assistance.
Best wishes,

Model J VM1650BB1 Microwave will not heat anymore. Was working fine the day before. All other items working...light, turntable and fan. What is the problem and how can I fix it?

The model is GE JVM1650BB1. After searching information on the internet, it is almost 100% the Magnatron that has stopped working. Unless I can get GE to give me the part for free and try my hand at replacing it, it does not make sense to pay to have it fixed. Whether GE or another serviceman comes to fix it, it will cost as much as a new one. For this unit, the Magnatron is over $100 from what I can tell.

If you have another suggestion, I'd like to hear it. Seems like GE and perhaps other brands have planned obsolescence with the Magnatron part. Amazing how there is no recall on this part and the consumer groups do not go after this. Good thing our airplanes don't have parts like this that can break in months or years.

GE JVM1870 Runs, but won't heat up

use a high voltage probe to check high voltage, if present replace the magnatron if no HV replace the high voltage board this is the board that has the heavy wires to the magnatron
