Troubleshooting Your Whirlpool WMH53521HV Microwave Problems

When your microwave starts acting up, it can be a major inconvenience, especially if you rely on it for warming meals quickly in your busy life. The Whirlpool WMH53521HV is a popular over-the-range microwave known for its reliability and advanced features like sensor cooking and a steam function. However, like all appliances, it can occasionally run into problems. In this post on TheKitchenApplianceDad.com, we’ll guide you through some common issues with this model and how to troubleshoot them.

1. Microwave Not Starting

Check the Door:
First, ensure that the microwave door is firmly closed. Microwaves have safety switches that prevent them from operating if the door is not properly latched.

Examine the Power Source:
Ensure that the microwave is plugged into a working outlet. You might want to try plugging another appliance into the same outlet to test for power.

Inspect the Fuse:
If your microwave is completely unresponsive, there could be an issue with the fuse. The fuse for the Whirlpool WMH53521HV is located behind the control panel. Replace it if necessary, but remember that if it blew, it might be a sign of a more significant problem.

2. Microwave Not Heating

Magnetron Issues:
The magnetron is responsible for generating the waves that cook the food. If it fails, the microwave will run but not heat. This component should be serviced by a professional due to the high voltage it handles.

Check the Diode:
The diode converts A/C power to D/C, doubling the voltage to nearly 5,000 volts. This powers the magnetron. If the diode burns out, the microwave won’t heat. Testing and replacing the diode should be done by a professional.

Door Switch:
If the door switch isn’t working, the microwave might not realize that the door is closed and won’t start the heating process. Check the door switches and replace them if they are defective.

3. Microwave Runs and Then Stops

Overheating:
If the microwave runs for a few seconds and then stops, it might be overheating. Make sure there is enough clearance around the microwave for proper airflow, and check if the internal cooling fan is operating correctly.

Faulty Thermoprotector:
This safety device can cause the microwave to shut off if it overheats. Test the thermoprotector for continuity and replace it if necessary.

Control Board Issues:
Sometimes, the electronic control board may be faulty. This problem is less common but can cause a variety of operational issues.

4. Unusual Noises

Turntable Motor:
If you hear grinding or other strange noises during operation, check the turntable motor. It might need to be replaced if it’s no longer working smoothly.

Roller Guide:
The roller guide under the glass tray can sometimes become gummed up with food particles or other debris, causing strange noises. Clean it thoroughly and check if the noise persists.

Magnetron:
If the noise is more of a buzzing sound, it could be an issue with the magnetron. As mentioned, servicing the magnetron should be handled by a professional.

5. Display Issues

Check the Display Panel:
If the display on your Whirlpool WMH53521HV is not working correctly, first check to see if any of the buttons have been locked or if the unit is in a demo mode.

Connection Issues:
Loose connections can also cause display issues. Unplug the microwave and remove the control panel to check all connections. If you’re not comfortable doing this, contact a professional.

Control Board:
If other troubleshooting steps don’t resolve the display issues, the problem might lie in the control board, which might need replacing.

Preventative Maintenance Tips

To keep your Whirlpool WMH53521HV microwave in top condition, follow these maintenance tips:

• Clean Regularly: Keep the interior free from grease and food splatter. Use a microwave-safe cleaner or a mixture of vinegar and water for natural cleaning.
• Turntable Maintenance: Ensure the glass turntable and its support are always clean to avoid uneven cooking or excessive noise.
• Door Seals: Check the seals around the door for any food particles or degradation that could prevent the microwave from functioning correctly.

Key Takeaways

• Check Simple Solutions First: Always start with the basics like ensuring the microwave is plugged in and the door is closed properly.
• Safety First: When dealing with high-voltage components like the magnetron and diode, it’s best to consult with or hire a professional.
