Hey there! Are you facing a problem with your Whirlpool Microwave WMH31017FS0? Specifically, is the exhaust fan not working as it should? Well, fret not, because in this blog post, we’ll dive into the possible causes and solutions for this issue. We’ll guide you through the troubleshooting process, step by step, so you can get your exhaust fan up and running again. Let’s get started!
1. Understanding the importance of the exhaust fan
The Role of the Exhaust Fan
When it comes to microwaves, the exhaust fan plays a crucial role in maintaining a comfortable cooking environment. It helps to remove smoke, steam, and odors from your kitchen, preventing them from lingering and affecting the air quality.
2. Check the power source
Power Source Check
The first thing you should do is ensure that your microwave is properly connected to a power source. Check the power cord and make sure it is securely plugged into an outlet. If the cord appears damaged, it may need to be replaced.
3. Inspect the fan motor
Fan Motor Inspection
To determine if the issue lies with the fan motor, you’ll need to inspect it. Start by unplugging the microwave and removing the vent cover. Locate the fan motor and visually inspect it for any signs of damage or debris. Clean the motor and surrounding area, removing any dirt or dust that may be obstructing its function.
4. Test the fan motor
Fan Motor Testing
After inspecting the fan motor, it’s time to test its functionality. Plug the microwave back in and turn it on. If you hear a humming sound but the fan isn’t spinning, it could indicate a problem with the motor. In this case, the motor may need to be replaced.
5. Check the fan blade
Fan Blade Check
Sometimes, the issue may not be with the motor itself, but rather with the fan blade. Inspect the blade for any signs of damage or obstruction. If the blade is bent or damaged, it may not be able to spin properly, resulting in the fan not working. In such cases, replacing the fan blade should solve the problem.
6. Examine the control board
Control Board Examination
If the fan motor and blade appear to be in good condition, the problem might lie with the control board. The control board regulates the functions of your microwave, including the exhaust fan. Inspect the control board for any visible signs of damage, such as burnt-out components or loose connections. If necessary, replace the control board to restore the fan’s functionality.
7. Check the fan switch
Fan Switch Check
Another possible culprit for the exhaust fan not working could be a faulty fan switch. The switch controls the fan’s operation, and if it’s malfunctioning, the fan may not turn on. Test the switch by disconnecting the power and using a multimeter to check for continuity. If the switch fails the continuity test, it will need to be replaced.
8. Verify the wiring connections
Wiring Connection Verification
Loose or faulty wiring connections can also cause the exhaust fan to stop working. Carefully inspect the wiring connections, ensuring they are secure and free from damage. If you notice any loose or damaged wires, they will need to be repaired or replaced.
9. Reset the microwave
Microwave Reset
Sometimes, a simple reset can fix minor issues with your microwave. Unplug the microwave from the power source and leave it unplugged for a few minutes. Then, plug it back in and test the exhaust fan. This can often resolve temporary glitches and restore the fan’s functionality.
10. Seek professional assistance
Professional Assistance
If you’ve tried all the troubleshooting steps mentioned above and the exhaust fan still isn’t working, it may be time to seek professional assistance. Contact Whirlpool customer support or a certified technician who can diagnose and repair the issue for you.
