    Yes, Both the light and the turntable come on. But we sense a burning smell when its on.



    A little louder then usual might be.



    GH7115xhs - That's the model number.



    Would it be easy to fix it on our own. Like replacing any part. Becuase some of the parts are still under warranty , but not the labour.

    When you hit Start to cook, do the inside light and turntable come on?

    Any unusual noises?

    Is it louder or quieter than usual?

    Do you have the model number?

I would suspect (in order) a shorted high voltage rectifier diode, a bad magnetron, or a bad high voltage diode.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Some manufacturers will send you the magnetron to do it yourself. If nothing else, you can save about $75 by taking it to the shop yourself.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/xformer.html

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

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

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.

GE Microwave PVM1790DR1BB light works but no fan and the turntable does not turn


I have this exact model with the same issue. I am a technician by trade on office equipment. I took the cover off where the door latches go in and there are 3 relay switches behind there. I adjusted the switches so the door latch would make better contact with them.

I have a KHMC106W Micro-Convect Hood - all of sudden when we used the microwave it didn't sound right and the food never heated up. I unplugged and waited about 2 min and replugged back in and it still...


the Magnetron has gone (yes it's really called that) that's the part of the microwave that emits radio waves and cooks your food... 30 years ago when this tech (Microwave cooking) was new and expensive it was cheaper to replace that part than buy new... now it's the other way around... at least you still have a working electric convection oven.
it's very rare that a Magnetron go bad, so look for an old one of the same model and use that one for parts if it's that loved.

Turns on but not heating food sounds a bit louder


Hi, this is common in most microwaves. this abnormal noise is coming from a faulty Magnetron. this device is responsible for the heating process and, it is damaged and not heating at all at this point.Simply replace the Magnetron and, this unit will start to heat once more.

3 year old unit, oven works, microwave does not


hi,

You may need a new magnetron, contact sharp or the store you got it from; most microwaves have a 3-5 year warranty on the magnetron. If it's not in warranty, find a good appliance repairman, this is a difficult and dangerous repair job.

Microwave does not heat/cook


hi

power spikes are very damaging to a microwaves internal parts, it sounds like your transformer and/or magnetron are blown. if the unit is out of warranty I would recommend calling a repairman or getting a new microwave (the transformer & magnetron are expensive and dangerous to work on) also get a small single plug surge protector for the new one.
