Most common repairs needed to fix a whirlpool microwave

When your microwave’s display isn’t working, certain repairs are more commonly required than others. Below are the most frequent fixes:

Replace a Blown Fuse:
A blown fuse is one of the most common causes of a non-working microwave display. To fix it, use a multimeter to test the fuse for continuity. If it’s blown, you’ll need to replace it with an identical part. This is a relatively simple DIY repair that only requires basic tools like a screwdriver and a multimeter.
Replace the Microwave’s Thermal Fuse (If Equipped):
The thermal fuse acts as a safety mechanism, shutting off the microwave if it overheats. Use a multimeter to test the thermal fuse for continuity. If it has blown, replace it with a compatible part. Make sure to investigate the cause of overheating to prevent the new fuse from blowing again. This often requires disassembling the microwave to access the fuse.
Repair Power Supply Issues:
Sometimes, the issue with the microwave display may stem from a power supply problem. Inspect the power cord for any visible damage or fraying. You should also test the wall outlet with another appliance to ensure it’s providing a stable power supply. If the microwave is plugged into a power strip, try plugging it directly into the wall. If you suspect a deeper electrical issue, it’s best to consult a licensed electrician to inspect the power supply.
