Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old


If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

MOST LIKELY YOU HAVE WHAT IS CALLED A MAGNETRON THAT HAS FAILED... IT IS THE PART THAT DOES ALL THE HEATING ...YOU DO ALSO HAVE A HIGH VOLTAGE TRANSFORMER THAT SEND POWER TO THE MAGNETRON BUT IT SOUNDS LIKE A MAGNETRON.... to be honest with you unless you are servicer it normally cost more to repair and for a few dollars more you can purchase a new one..... good luck to you.....

MICROWAVE NOT HEATING


Most likely you have a magnetron problem. Easy to replace (DYI) but make sure the high voltage capacitor is fully discharged first against the case.

Microwave does everything that it is supose to do just that it does not heat and the noise to heat increased. This happend yeaterday.


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Microwave JE1650AA 002 Light, timer, panel display and beeper all work but the microwave nor the turntable work.


Hi worzelh,

When a microwave suddenly stops heating food, but still appears to run (the control electronics and light are usually a separate circuit), it's usually a defective/dead magnetron.

The turntable _may_ or may not be on the same circuit as the magnetron, that's hard to say without a wiring diagram or schematic.

Prices for replacement/repair will vary, you will need to find out what that service costs in your area before having enough information to decide on repair or replacement. If you tell the repairer that you suspect the magnetron, they should be able to quote you a fairly accurate estimate.

When my first microwave lost it's magnetron (~20 yrs ago), it was 5 years old at the time, and the cost of buying a new oven was only a little more than the repair - but I had the repair done anyhow. Since then, we've replaced the entire oven instead (twice). Newer ones may have more power/less energy wastage, etc.

If I can be of further assistance, or if you have questions about any of my response(s), please let me know before rating me.

If this solves the issue, please rate it accordingly. My goal is to earn a "FixYa" rating from everyone I help.

Thanks for using Fixya.com,

Jon

Whirlpool Microwave no longer heating


Sounds like the magnetron has failed. It is the magnetron that generates the microwaves that heat the food. If it or the circuit that powers it fails then it stops heating. There are some high voltage circuits that feed the magnetron and you can potentially get hurt if you don't know what you are doing. Would recommend you have it serviced by a professional if you want it fixed, otherwise look for a new one since the cost of repair can come close to the price of a new microwave oven.
