How to Fix a Whirlpool Microwave

Check the Power Source

Let’s begin with the initial step: ensuring that the power source for your microwave is functioning properly. You can perform this by following these steps:

1. Examine your household fuse box and ensure that the circuit breaker responsible for supplying power to your kitchen is in the “on” position. If it’s not, switch it on.
2. Carefully inspect all the fuses. If you come across a blown fuse, you’ll need to replace it.

Check the Turntable

The following step involves inspecting the turntable in your Whirlpool microwave. To do this, follow these steps:

1. Turn your microwave on (use any cycle) and carefully observe the turntable to check if it’s rotating. If it is indeed rotating, then this isn’t the root cause of the issue, and you should proceed to the next component for inspection.
2. However, if you notice that the turntable is not rotating, proceed as follows:
   • If possible, remove the rollers and hubs from the turntable.
   • Thoroughly clean these components.
   • Reassemble all the components, ensuring that the turntable is correctly positioned on the turntable support.
3. If, after cleaning and reassembling, the turntable still does not rotate, you’ll need to replace the turntable components.

Bosch microwaves are known for their advanced technology and precision. They may include innovative features like European convection, speed cooking, and more, often catering to users who seek high-performance appliances.

Alternative to Whirlpool Microwave

Panasonic Microwave

Panasonic microwaves are known for their heating and advanced inverter technology. They are available in various sizes and styles.

Check the Display Messages

Moving forward, it’s essential to check for display-related issues that can be easily resolved. Begin by:

1. Resetting the Clock:
   • Press the “clock” key on your microwave.
   • Use the number keys to set the correct time.
   • Press the “clock” key once more to confirm and set the time.
2. Ensure the Microwave Isn’t in “Locked” Mode:
   • Check the display, and if it shows “Locked,” the microwave is in lock mode.
   • To unlock it, press and hold the “off” key for five seconds.
   • Once unlocked, you should be able to use the microwave as usual.

Check the Line Fuse

If you haven’t resolved the issue with the above steps, you can proceed to check the line fuse. The line fuse can lead to a microwave malfunction when excessive current flows through the circuitry, causing the fuse to blow. Here’s how to check the line fuse:

1. Safety First:
   • Unplug the microwave from the wall to ensure your safety during the inspection and repair.
2. Access the Line Fuse:
   • Carefully remove the microwave’s case or cabinet to access the internal components. Locate the line fuse within your microwave.
3. Check Fuse Continuity:
   • Utilize a multimeter to test the fuse for continuity.
   • If the fuse shows continuity, it means it is not blown and is not the cause of your problem.
   • If the line fuse lacks continuity, it needs to be replaced. However, it’s crucial to identify the root cause of the problem to prevent future fuse blowouts.

IMPORTANT WARNING: Repairing microwaves can be extremely hazardous and should only be attempted by individuals with the proper training. Microwaves store thousands of volts of electricity in their capacitors even after being unplugged, posing a high risk of electric shock. If you’re not experienced in microwave repair, it’s recommended to seek professional assistance to ensure your safety.

Check the Thermal Fuse

The thermal fuse is a safety feature that cuts off power to the microwave in case of overheating. To check the thermal fuse, follow these steps:

1. Safety First:
   • Ensure that the microwave has been turned off at the wall to prevent any electrical hazards.
2. Check Thermal Fuse Continuity:
   • Use a multimeter to test the thermal fuse for continuity.
   • If the thermal fuse lacks continuity, it needs to be replaced. Note that it is not possible to reset the thermal fuse once it blows.
3. If Thermal Fuse Has Continuity:
   • If the thermal fuse shows continuity, it means it is functioning correctly and does not need to be replaced.

IMPORTANT WARNING: Microwaves are exceptionally dangerous to repair due to the high voltage stored in their capacitors, even after being unplugged. There’s a substantial risk of electric shocks. It is strongly recommended that only licensed technicians or qualified professionals attempt to test and replace electrical components in microwaves to ensure safety.

Check the Thermoprotector

Another critical component to inspect is the thermoprotector, which serves to interrupt the voltage to the microwave in the event of overheating. Here’s how you can check the Thermo protector:

1. Prioritize Safety:
   • Ensure the microwave is completely unplugged from its power source to prevent any electrical risks.
2. Check the Thermoprotector:
   • Use a multimeter to check if the thermoprotector has continuity.
3. Addressing No Continuity:
   • If the thermoprotector does not exhibit continuity, you can attempt to reset it. If a reset doesn’t resolve the issue, you will need to replace the thermoprotector.
4. Thermo protector with Continuity:
   • If the thermoprotector maintains continuity, it is functioning correctly and does not require replacement.

IMPORTANT WARNING: Repairing a microwave can be dangerous due to the risk of electric shock, as microwaves store high voltages in their capacitors, even when unplugged. It is highly recommended that only licensed technicians or qualified professionals handle the testing and replacement of electrical components in microwaves to ensure safety.

Replace the Main Control Board

The final component to consider if you’ve exhausted all other options and still can’t identify the cause of your microwave’s malfunction is the main control board. While it’s relatively uncommon for the main control board to be the root cause, it can sometimes be the issue.

If you’ve gone through all the previously recommended solutions and the problem persists, replacing the main control board may be necessary.

IMPORTANT WARNING: Microwaves are exceptionally hazardous to repair if you lack the proper training. They store high voltages of electricity in their capacitors, even after being unplugged, which poses a significant risk of electric shock.

Therefore, it is strongly advised that only licensed technicians or qualified professionals undertake the testing and replacement of electrical components in microwaves to ensure safety.

Conclusion

When faced with a Whirlpool microwave that is not working, there are several potential issues to consider. We’ve covered various troubleshooting steps in this guide to help you identify and rectify the problem.

It’s important to ensure your safety by following proper precautions and consulting licensed technicians when dealing with electrical components, as microwaves can store high voltages of electricity in their capacitors, even when unplugged.

By following the steps outlined here, including checking the power source, examining the turntable, assessing the display, and inspecting components like the line fuse, thermal fuse, thermoprotector, and main control board, you can systematically diagnose and potentially resolve the issue.

Remember that safety is paramount, and it’s essential to exercise caution when attempting any repairs or replacements within your microwave. If you’re uncertain or uncomfortable with these procedures, it’s always advisable to seek professional assistance. Your well-being is a top priority in addressing the “Whirlpool Microwave Not Working” issue.
