Chefmate microwave will not heat up anything

Microwave is less then 2 years old and all of a sudden yesterday it stopped heating up food that was put in there. I know this is not a top of the line microwave oven but it should last more then 2 years.

A microwave not heating up is caused by one or more of the following -

1) Failed controller board (unlikely if you are getting a clock readout and you can get the various functions to work, just no heat)
2) Failed door switch
3) Failed thermal fuse, when used
4) Blown power fuse that is dedicated to the microwave circuit
5) Bad diode
6) Bad capacitor
7) Bad magnetron
8) Bad transformer

Door switches insure the microwave circuit will not engage when the door is open. Slamming the door of the microwave is hard on the switch.

The thermal due is wired into the microwave harness, and is a melting allow type, based on heat buildup within the oven. Always replace with a fuse of the same thermal rating.

The power fuse is a special type and should only be replaced with that same type and rating. It is easily tested.

The diode is a relatively inexpensive part, and is not easily tested. If a grumble is heard coming from electrical area of the unit, then the diode could be shorted.

A shorted capacitor will blow the fuse immediately. And open capacitor will cause a "no heat" condition.

A bad magnetron will also cause a low level hum or grumble from the transformer. But is may also cause no other identifiable symptom of failure.

A bad transformer will exhibit a grumble or hum, and may or may not blow the fuse. But be careful here, the secondary of the transformer produces very high voltages, up to 2.5Kv. Few people own a meter capable of measuring such voltages.

Service and repair of microwave ovens is dangerous work. If you don't know what your doing, DO NOT ATTEMPT TO SERVICE A UNIT WITHOUT INSTRUCTION.

My Sunbeam Microwave SGB8901 lights up and seems to be working, but it doesn't heat anything. Is this fixable?


Only 2 years old? Hopefully you still have owner's manual, troubleshooting section should help you look for the problem. Hopefully, there is a circuit breaker, or perhaps a fuse. I hope it was not used with a metal object accidentally. No help? Check with Sunbeam Customer service, be nice, they usually are helpful.

Why did my whirlpool microwave display quit, everything else works. less than 2 years old


Over the range ovens of all brands are prone to failure of the electronics due to heat and steam from the food that's cooked on the range below them. It's not extremely common, but you do see more of these types of failures on these as opposed to counter top models.

I have a neff combi microwave oven and it stops working after 20 seconds and doesn't heat the food


It is one of three things, the microwave oven, "heart of the system" inverter board, "if less than 7 years old" and the keypad control board. all parts mentioned are not cheap.

No Heat.


Hi dadedulitl,

When you say "putting out no heat", I take that to mean it's not heating the food up. When a microwave suddenly stops heating food, but still appears to run, it's usually a defective/dead magnetron. Prices for replacement/repair will vary, you will need to find out what that service costs in your locality before having enough information to decide on repair or replacement.

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 one's may have more power/less energy wastage, etc.

If it's ~ 3 years old, do you have an extended warranty?
If so, you might be able to use that (check the terms of the EW). Most standard warranties are for 1-2 years max, so unless you bought the EW, you're probably back to deciding between repair and replacement.

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,

Microwave not working, please suggest


Your magnetron tube has failed. According to the warranty on the Profile Series microwave ovens, the magnetron is covered for 5 years from the date of purchase, but labor is not included. I would call GE Customer Service and when they ask for the model number (which begins with JVM) and the serial number, be sure to give the date of purchase as the date you closed on your house. If they insist upon charging you for a service call and labor, I would call my builder's Customer Service Department and demand (very nicely) that they intervene with GE to waive the service and labor charges. That worked for me (Lennar Homes).
