If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. If you hear an unusual buzzing noise, the magnetron (the component that actually generates the microwaves) or other electronic module may be broken. If you hear nothing, you might have a defective transistor on the main printed circuit board. This is not easily fixed; contact a service technician. You can try the "find a microwave repair..." link from the product page. Good luck!

Sorry, I put the wrong warning there. Basically the same - WARNING: Microwave ovens are the most dangerous consumer appliance to
service due to up to 5,000 V at high current inside. Even with the
power off, there is a HV capacitor that can produce quite a lethal kick. This capacitor must be discharged before touching anything in the microwave generator circuitry.
DON'T remove the cover yourself unless you fully undertand the SAFETY issues involved in working inside a microwave oven. A microwave oven is possibly THE MOST DANGEROUS common consumer product to service.

Microwave timer works but will motor will not run/cook.

If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.

Do the inside light and turntable come on when you try to cook?

Is it making any unusual noise or is it louder or quieter than normal?

Do you have the model number?

Microwave oven does not heat anything. Clock, turntable, lights work. I turned the turntable off while the oven was cooking--heard a noise, now it doesn't heat anything.

Spacemaker XL 1400 worked for 7 years.Yesterday, no more heat. Also plastic door damaged.
will try Panasonic or something commercial

Microwave turns on, but no heat or turntable movement

The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck
