Common Microwave Problems Microwave Sparking
-
Microwaves are one of the most used appliances in modern kitchens. They heat food quickly, save time, and make life easier. However, just like any other appliance, they can run into problems. In this blog, we’ll cover some of the most common microwave problems and provide tips on how to try to fix them quickly before calling a technician.
-
1. Microwave Sparking (Arcing)
Issue:
You hear a crackling sound or see sparks inside the microwave.
Quick Fix:
● Stop the microwave immediately.
● Remove any metal objects (like forks or foil).
● Check if the waveguide cover (usually on the side wall) is dirty or damaged. Clean it gently or call a technician if it's burnt.
● Avoid placing dishes with metallic trim or foil in the microwave.
-
2. Microwave Not Heating
Issue: The microwave runs, but the food stays cold.
Quick Fix:
● Make sure the door closes properly. A loose latch can stop heating.
● Try a different power socket.
● If the microwave turns on but doesn’t heat, the magnetron (the heating part) may be faulty. You’ll need professional help for this.

3. Microwave Starts Then Stops
Issue: It runs for a few seconds, then shuts off.
Quick Fix:
● Check for overheating. Let the microwave cool down.
● Unplug for 10 minutes and try again.
● If it still stops, the control board or sensor might need repair.
-
4. Microwave Won’t Turn On
Issue: No lights, no sound — nothing.
Quick Fix:
● Confirm the microwave is plugged in properly.
● Check if the outlet has power (try plugging in another device).
● If there’s power and it still won’t start, the fuse or internal wiring might be the issue — time to call a technician.

5. Microwave Making Strange Noises
Issue: You hear buzzing, grinding, or clicking noises while the microwave is running.
Quick Fix:
● Ensure the turntable is positioned correctly on the ring.
● Remove any loose objects or spills inside.
● If the noise continues, the fan or motor may be worn out and needs servicing.
-
6. Microwave Plate Not Spinning
Issue: The turntable isn’t rotating.
Quick Fix:
● Check if the plate is securely positioned on the roller ring.
● Clean the ring and bottom area to remove any stuck food.
● If the motor below is not working, it may need replacement.
-
7. Microwave Heating Food Unevenly
Issue: One side of your food is hot, the other side cold.
Quick Fix:
● Stir or rotate your food halfway through heating.
● Use flat, round containers to help heat spread evenly.
● Clean the inside of the microwave to avoid blocked heat paths.
-
8. Microwave Takes Too Long to Heat
Issue: Your usual 1-minute warm-up now takes twice as long.
Quick Fix:
● Avoid overloading the microwave.
● Ensure the power setting hasn’t been accidentally reduced.
● If it’s still slow, internal parts, such as the magnetron, may be weakening.
-
9. Microwave Touchpad Not Responding
Issue: The buttons don’t work, or work only sometimes.
Quick Fix:
● Wipe the touchpad clean with a soft, dry cloth.
● Check if the child lock is on (refer to the user manual).
● If it still doesn’t respond, the control panel might need repair.
