Microwave runs but does not heat.

My microwave has stopped heating yet still runs. Now this happened the same day and time my rifridgerator quit!! In my town we have had a few power outages, one lasting 30 mins, but this problem did not occur until two days after the outage. Is this a fixable problem or should the microwave be tossed. It is dated August of 2001 so it is 6 years old.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board

What causes a ge spacemaker above the range microwave to quit heating and makes a deeper pitched noise?

This louder, 60 cycle hum is usually caused by a bad magnetron. The unit will not heat when this happens. Repair cost can exceed $100.

DANGER WARNING! Potential Hazard if your microwave was working and now doesn't...

If you have this model microwave and it was working fine, then one day it stopped heating items placed inside there are a handful of different issues that could be the problem. In my case it was intermittent, over a period of a few days it would sometimes work (heat) and sometimes not. NO MATTER if this is what your's is doing or if it stopped heating all together. If you decide to let it dry out, or not use it for a while to see if it was a one time occurrence, or whatever the reason, the first time you put something in and probably for the next 10 times at least (this assumes it starts to work again), make sure you are right there with it while it is cooking. Don't assume you can put something in, go do something and come back when the timer is beeping. There is a chance (as this happened to me) that your food inside will CATCH FIRE! Normal food item placed inside, no metal, nothing different than the numerous times before when this had been cooked but when we smelled smoke we came running. Fortunately it started and finished inside the microwave but that's not a guarantee, it could spread. Play it safe. Never had a problem like this before and never heard of a microwave cooking something until it caught on fire (especially since the time entered for the cook was 30 seconds) but it did.

Microwave doesnot heat anything

6 years is a good run for a microwave to keep working
as it is basically a high frequency radio transmitter, take it in for a proper diagnosis and a quote
mostly after 6 years there may be a shortage of parts available for repair so keep in mind that it may be cheaper to junk it and get a later model

The microwave stopped heating. Everything else is working fine.

Ok, concerning the heating issue. you will need to replace the Magnetron to restore the heating feature in this unit. this device is damaged.

Concerning the motor(circulation). If the motor is not working, this will damaged the Magnetron, due to poor circulation. i recommend replacing the motor asap.

In conclusion, you will need to replace the Magnetron and the circulation motor as well. replacing these two vital devices will fix your issues. the total cost for these parts are estimated at $87.90

Microwave won't heat anything

Yeah, it's time to invest in a new oven. The magnetron tube in yours most likely just finally wore out. It's the source of the microwaves, and like any tube it gets weaker with age and finally just quits altogether. It would cost more for a new magnetron than it would for a new oven these days.

Microwave appears to work fine but will not heat at all.

Sounds like the thermal protector on the mag tube quit. It may have gotten too hot and opened up. That is the lesser of all the evils that can happen to a Microwave.

GE SpaceMaker Microwave suddenly stops while heating

I had same problem last week. My GE JVM1650 Spacemaker stopped after a few seconds of heating. Owned 16 months, manufactured Jan 2005. It was the magnetron, which was replaced yesterday. The magnetron has a 10-year warranty, but I had to pay $161.00 for labor by a GE technician. The call-out fee was waived at my request. I don't know what that amount would have been, but I can't believe the $161.00 for what was about 1/2 hour labor once diagnosed. Good Luck!
