GE spacemaker microwave turns off during cooking and display goes black


Step 1:


Door Switch




If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently

Step 2:

Main Control Board




If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.


Touchpad and Control Panel




If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad




If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer




If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermostat




If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

My microwave oven just stopped cooking. The light comes on and the Motor is running, but much louder than normal.


The magnetron in your microwave has probably gone out. The magnetron is the part of the microwave oven that produces microwaves. If you unit is a built in model, it will likely cost more to fix than a new one. Same thing goes for a countertop unit.

Door will not open. Button release does not release the door latches.


The plastic lever release is more than likely broken. You can order the part from

It's about twenty dollars.

Neff Microwave H5470SOGB


if appliance runs for approx twenty seconds this is nearly always a magnetron fault usually a cracked magnet or burnt out anode the electronics are detecting an unusual power fluctuation and shutting appliance down for safety you will need service tech to sort.

Microwave shutsdown after 24 seconds, does not heat up


Classic symptom of a defective inverter. It it's under warranty, you're probably in luck. If not, expect repair costs of about $120-150. If you can find a servider who will repair the inverter instead of just replacing it, you can save some money. If you or a friend can replace it yourself, you'll really save, assuming you follow safe procedures. You can find my file "safety.txt" via a Yahoo search. It is part # A606Y5X00AP for model NN-T993S and runs $62.83 plus shipping. The inverter can be gotten from Panasonic at http://www.pasc.panasonic.com/epartr
