Since the light comes on and the turntable rotates, I would suspect a bad magnetron, a loose connection at the magnetron, a failed high voltage transformer, or shorted high voltage rectifier diode.

If it's less than one year old, it should be fully covered under warranty.I'd suggest contacting the manufacturer to get it fixed free.

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

If you or a friend want to work on it, please see these links first:http://www.microwavedisplay.com/safety.txt& http://www.microwavedisplay.com/disassembly.txt

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)
http://www.gallawa.com/microtech/mag_test.html
http://www.gallawa.com/microtech/xformer.html

Thereshould also be a "mini-manual" hidden inside the unit behind thecontrol panel or hidden on the left side behind the grille, which isvery helpful when troubleshooting & testing.

Makes grinding sound when turned on---does not heat---turntable does turn


Grinding sound may be the turntable not sitting properly on its support. Regarding the heat issue, check the door safety interlock switches for proper function.

As you use your oven, open the door while it is running, arcing occurs on the little contacts and they eventually burn. When they cannot make contact, the oven doesn't know if the door is closed or not. Forget what YOU know about the door ... the oven must know and it knows by the information it gets from these switches. Door open, the oven will not turn on the heat.

Won't heat and turntable doesn't turn


In all likelihood the mangnetron has failed, or perhaps even something in the Power Supply. or a fault that is shutting the system mangnetron down, for safety reasons 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.

Turntables doesn't work and makes horrible noise


Replace turntable motor. Not really that hard to replace or expensive. Remove all screws holding bottom panel (usually three across each side and one to three in front) to gain access to the turntable motor. The panel will hinge in the back.

TURNTABLE DOESN'T TURN.


Does the rest of the oven's functions work? Does the front panel controls work? Does it heat up the food? If yes, this indicates that you might have a problem with the motor that turns the turntable.

If you try to turn the turntable manually (gently), does it turn freely or is there resistance? If it turns freely, the mechanical mechanism between the turntable and motor may be broken and the motor may be ok.

The oven's microprocessor also controlls the motor. There could be a problem there.

You'll need to have it looked at by a service center. Although its not that difficult to determine which of the reasons I mentioned above is the cause, it can be however, dangerous to operate a microwave oven with the cover off and with high voltage circuits exposed.

Please let me know if I can be of further assistance to you.

Good luck!
