Repairing a GE microwave begins with performing a soft reset followed by a hard reset. If the machine fails to work when the power is on, check if the fuse is intact. It is prudent to troubleshoot in order to know the source of the malfunction. Some of the common problems that need repair include unresponsive buttons, failure to power on, and erratic behavior of the machine.
- Check the functioning of the machine controller
Problems associated with the malfunctioning of the machine controller include unresponsive buttons, blank display, touchpad malfunctioning and failure of the stat button to function. Another symptom of controller malfunctioning is the microwave starting by itself when the door is shut. To solve this problem, unplug the machine to perform a hard reset.
- Check if the machine powers up
Sometimes the microwave that has been recently repaired can fail to power up. Such a problem happens because of the failure of the interlocking screw to engage fully. To repair this problem, check the screws on the top, back and sides of the machine, and ensure the screws function.
- Repair the erratic behavior
Mechanical problems cause erratic behavior in microwaves. Most machines that do not have a rotating tray encounter this problem. To repair this problem, unclip the plastic cover found above the oven cavity, and check for broken or worn parts. If the problem persists, use a microwave power indicator to check for other problems.
