Hope helps.

I checked the owners manual and it does not list the fault codes. Manufactures leave this information out of the manual most of the time so you have to call them for service.

Call 1-800-4-my-home (sears) and tell them the problem. You will also need to provide the m# so have that ready when you call.

Good Luck

You're going to have to replace the keypad module and possible the control module (do the keypad first). You can try contacting these folks: http://www.appliancepartspros.com/search.aspx?model=jem31sa%20001%20ge%20spacemaker%20microwave
And see if they have a keypad for your unit. Depending on the age of your microwave, you may be best off replacing the whole microwave.

If your microwave has a turntable its probably just burnt food inside or above the oven chamber that has carbonized. If it doesn't have a turntable its possible the stirrer above the oven chamber is stuck and not moving the microwaves around, therefore causing over heating and arcing. It also could be that the stirrer blades are hitting inside. Hope this helps

Sometimes a keypad may not work because the door switches are faulty. When the door switches are working correctly it will allow the keypad to operate. They tell the microwave that the door is closed and the unit is dafe to use.

Many models have 3 door switches, it's wise to get all 3 replaced at once.

control panel is hung up - replace panel and keypad.

It may possibly be locked, in which case holding the enter/start pad for over 3 seconds may unlock it.

Otherwise, you may want to call Maytag / Amana at:
