Check the back panel for a breaker reset. If none, remove the case cover (pull the plug) and look for any blown fuses. If look ok, then check the interlock switch(es) for function when the door is closed. They are micro-switches and should make a distinct 'click' when operated. If you find a blown fuse, replace the high voltage diode in the magnetron power supply and replace the 'stirrer' (a fan-like device located under the sheet metal wave guide where the microwave energy enters the cooking cavity). It has a plastic bearing that can arc across inside it and short the energy out.

Unplug the Micro for about 5 minutes and plug it back in this will reset the board,it may have picked up interference from other electronics.If the issue continues have a technician look at it.

Hello. check to be sure that you have power to the outlet where your microwave is plugged in. If you do then plug your microwave in and attempt to set the clock. IF you can not set the clock you most likely have a blown internal fuse. Call around to the various repair shops and tell them what you need. get an estimate from at least three shops.

It sounds like you may have accidentally set the child safety lock. Some ovens have this feature as a safety device to prevent children from manipulating the controls.

If the model number is not correct, post back with your correct information, or refer to your owner's manual under the "Operating Instructions" section.

make sure you loads are balanced, put heaviest clothes in first... if you can rock it by hand then the legs are not adjusted properly. If you stand 2 feet away from front of machine, jump up and down and see it move the floor is soft and you need 2 sheets of plywood to make 1 1/2 inches put under the machine

Damage to the magnetron tube.

The spindle (called a turntable shaft) sits atop a small motor shaft from the turntable motor. You either have a weak turntable motor, stripped shaft (which allows the motor shaft to free spin when it has any weight on it), or both.

The turntable motor is located under the bottom panel of the microwave oven. You do not have to uninstall the oven for this repair.

First, unplug the unit, remove the glass carousel tray, and pull straight up on the turntable shaft to remove it. Next, locate and remove the series of screws along the bottom panel underneath the oven. The bottom panel will open exposing the drive motor. The motor comes out by disconnecting the connector plug and a couple of mounting screws.

If the model number you have this listed under is correct, you can view these parts at searspartsdirect.com. Locate items 11 (turntable motor) and 14 (shaft) under the "Cavity" heading. Other sites you may try are pcappliancerepair.com, appliancepartspros.com or repairclinic.com to see if you can find these parts any cheaper.

If you have any questions, please let me know. I hope you find this information helpful.

HI. this is called Magnetron failure. you will need to replace this failed device. it is responsible for the heating of the contents.

may i please ask you if you have a meter? check that 120 volts is going in? check the buttons that you press. also check the fuse check the mains cable for any breaks. also you may want to test the display to see if any power going in?

Test the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.
