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.

Our Sunbeam microwave is plugged in. It turns on and the clock works but the heating inside isn't working...Help!

microwaves are cheap, get a new one. There is a capacitor inside every microwave which can store thousands of volts so it is unsafe to pull cover by homeowner and it costs more than it is worth to have it repaired.

Sunbeam microwave not heat

Place a glass pie plate in the oven with about 1/8" deep water in it. Turn the oven on high for about 30 seconds. If you get one small spot with intense boiling, the stirring antenna at the top of the oven is not rotating. It's usually driven by a small 60 RPM synchronous motor. To get at it, look for a pull-out plastic locking pin that holds the plastic dome or plate to the tope of the oven cavity. You may need to rotate the cover counter-clockwise a fraction of a turn to unlatch it. Sometimes greasy food vapor gets in there and gums up the bearings. Clean very thoroughly, but be careful not to bend the antenna blades. When you reassemble, make sure the antenna is properly seated in its bushing and engaged on its drive shaft. Repeat the test to see if you have even heating.

If you see no evidence of heating anywhere in the oven, check to see if the door switch in series with the transformer is malfunctioning. If the door switch is OK, you'll need a high-voltage measurement probe to determine whether the magnetron has failed, or (more likely) the high-voltage capacitor or diode is bad.

How do i replace a fuse on sunbeam microwave

If it does not heat, the magnetron tube died. Not worth repairing unless under warranty. Generally the only fuse is a main fuse. If it blew, the entire microwave would be dead.

My delonghi microwave mm821aan-x2 is not heating. the turnstable is working and the light it a part i need to make it work?

Could be several things. Fuse blown to the magnetron circuit. Bad magnetron or fuse and HV diode blown to magnetron circuit. The fuses are only about $5 at . If the unit is extremely old the magnetron could be bad but generally it is the fuse and HV diode. For the cost of the parts it would certainly be worth fixing if you have the ability. Let me know how it works out.
