SOURCE: microwave dead

First, there is an outlet. Plug in something else. Inside the key panel, there are fuses and a thermo sensor. Either may be bad. The thermosensor is about the diameter of a dime, black and 3/8 inch thick...attached to the wall of the chamber. All should have continuity.

SOURCE: I would like to find an electrical schematic for a

Couldn't get a schematic from GE. CSR told me they consider the unit a throwaway if it fails. Only parts they stock are the glass turntable and the roller ring. I ended up probing and metering the 110v power circuit. I found an open thermal cutout that was preventing power to the control panel. I removed it and took it to a local parts store and matched it up with a generic cutout with the same specs. Installed new unit and the oven is working like new. Cost: $15.00.

SOURCE: completely dead. no light, no heat, electric plugs

some models have a glass fuse that may blow. take the two screws off the top holding the grill on and remove. also unplug the mw and rub a screwdriver across the plug ends to discharge the capasitor.there should be one screw holding the control pannel on remove it and slowly lift the panel up and off. look for a glass fuse. check it with a meter or bring it to a hardware store. hopefully it is your problem.if not you should call for service.

Need to know correct size of microwave door glass for LG model MG-604w mine is broken after a fall, can I still use without glass?

NO, do not use the microwave with a broken door glass, this glass is specially protected to stop any dangerous microwave leakage, it is also something you cannot replace yourself, take it to a reputable service centre so that once the glass has been repaire the oven can be tested for safety purposes.

Kitchenaid Microwave Oven model Kcms1555rss stuck on same cooking time. There is a line with 3 other lines also on the screen

Hello :

It could be a bad door switch or loose door switch mount . There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly .

Warning : A microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. I strongly recommend you seek the assistance of an appliance repair technician when conducting any microwave oven repair .

good luck .

please rate !

Replacement part number???

Use the linkk below to order a new part -

Uk £22 + the usual vat + delivery.

To be honest, you would be better watching Ebay. If you know the diameter of the runners, and overall size of plate, you should get one to your door for under £10 .

Hope this helps you.
