Is your Whirlpool dryer showing the error code F43?

Don’t worry, we’ve got you covered! As experts in appliance troubleshooting, we understand how frustrating it can be when your dryer suddenly stops working properly. The F43 error code specifically indicates a problem with the heater thermistor, either it being shorted or grounded. But what does this mean, and how can you fix it?

Let’s dive into the nitty-gritty details and find a solution to get your Whirlpool dryer up and running again!

Understanding the Error Code F43

Before we jump into the solution, let’s first understand what the F43 error code signifies. The heater thermistor is an essential component of your dryer’s heating system. Its primary function is to monitor the temperature inside the dryer and ensure it remains within safe operating limits.

If your dryer’s control board detects that the heater thermistor is shorted or grounded, it will display the F43 error code on the screen. This error code indicates a potential issue with the heating system that needs your attention.

How to Fix the F43 Error Code

Fortunately, fixing the F43 error code is not as complicated as it may seem. Here’s a step-by-step guide on how you can resolve this issue:

1. Unplug the dryer: Before you begin any repairs, it’s crucial to disconnect the dryer from its power source. Safety always comes first!
2. Access the back panel: Locate the back panel of your Whirlpool dryer and remove it. This will give you access to the internal components.
3. Locate the heater thermistor: Once the back panel is removed, look for the heater thermistor. It is a small component usually located near the heating element or the blower assembly.
4. Inspect for damage: Carefully examine the thermistor for any visible signs of damage or wear. If you notice any frayed wires, burn marks, or other issues, it’s likely the root cause of the error code.
5. Replace the thermistor: If the thermistor appears damaged, it needs to be replaced. You can find the compatible replacement part from a reputable appliance parts store or directly from Whirlpool.
6. Install the new thermistor: Once you have the replacement thermistor, carefully install it in the same position as the faulty one. Make sure all connections are secure.
7. Reassemble and test: Put the back panel back in place and plug in the dryer. Turn it on and monitor for any error codes. If the F43 error code no longer appears, congratulations! You have successfully fixed the issue.

If, even after following these steps, the F43 error code persists, it may indicate a more complex problem with the dryer’s internal wiring or control board. In such cases, we recommend consulting a professional technician or contacting Whirlpool’s customer support for further assistance.

Check the wiring connections and the heating element for any damage or wear. Replace any faulty components to resolve the F43 error code on your Whirlpool dryer.

In Conclusion

The F43 error code on your Whirlpool dryer indicates a problem with the heater thermistor being shorted or grounded. By following the steps provided above, you can fix this issue yourself and have your dryer up and running in no time.

Remember, always prioritize your safety when dealing with any appliance repairs. If you feel uncomfortable or uncertain, don’t hesitate to seek professional help. Your dryer will thank you!
