It could be the circuit board, or it could be the cable that attaches the keypad to the circuit board has come loose.

  1. Main control boardIf your microwave runs for a few seconds and stops, the first thing to check is the main control board to ensure that a shortage has not occurred. If the part is defective then it will need to be replaced to prevent continual shut offs. If this is not the issue, the next step would be to check for a faulty touchpad.
  2. Touchpad/Control panelIf the control board is not the issue and your microwave continues to shut off after running for only a few seconds, the next thing to check is your touchpad, which is also known as a control panel. Although uncommon for this issue, symptoms are usually that the display and some buttons are working properly; however, when selected some buttons are not functioning. If this is the case the touchpad will need to be replaced.

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

How do you replace the touchpad on a sharp


If one or more of the keys are not responding when you press them, it may need a new keypad, or it may just be that the connections need cleaning.

On some of these models, the display and keypad are connected to the circuit board via a conductive rubber zebra strip.

Sometimes steam (or spray cleaners!) can get in there and interfere with conductivity for the keys and/or display.

One would have to take it apart and clean the connections with high-grade alcohol, like 70% or better isopropyl from the drug store.

The attached photo is similar but not the same model.

If the keypad has been damaged or a cleaning does not do it, you will need a new keypad, and disassembly can be a bit tricky.
