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.

I have a Sunbeam Microwave Oven SMW777 - 120V-60Hz. It stopped working two weeks ago - - I can set the time for the clock function but it will not cook/heat anything - won't allow me to set a time to cook...

In all likelihood the mangnetron has failed, or perhaps even the Power Supply. You need to have it serviced by a reputable service centre/man.
Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Microwave will not stop

Sounds like you have a bad door switch.  Will have to take control panel off and test switches resistance to see if they are opening and closing properly.  If a switch is stuck in or bad the microwave thinks the door is closed.  This is where I would start.  Let me know what you find.

Will not heat

The loud pop was almost certainly the high voltage diode going bad. To find parts, I suggest you call the number on your owner's manual or check with the store where you bought it. Sunbeam may not make this part available, so be prepared. Maybe they have authorized servicers in your area. Ask them about that. Good luck.
