Is your Whirlpool dryer showing the F42 error code? Here’s how to fix it!

As an expert in the field, I understand the frustration that comes with any error code on your appliances. Today, we will be discussing the F42: Heater thermistor open error code that you may encounter on your Whirlpool dryer. Fear not, for I have the knowledge and expertise to guide you through solving this issue and having your dryer up and running in no time!

The F42 error code is an indication that the heater thermistor is open. In simple terms, it means that there is an issue with the component responsible for monitoring and regulating the dryer’s temperature. When the thermistor is open, it fails to provide the necessary data for the dryer to function properly.

So, how do you fix the F42 error code?

1. Unplug your dryer: Safety first! Before attempting any repairs, make sure your dryer is completely disconnected from any power source.
2. Access the heater assembly: To fix the F42 error code, you’ll need to access the heater assembly. This requires removing the back panel of your Whirlpool dryer.
3. Locate the thermistor: Once the panel is off, you’ll easily spot the thermistor. It is a small device with two wires attached to it.
4. Check for continuity: Now it’s time to test the thermistor for continuity. Set your multimeter to the appropriate setting and touch the probes to the two metal contacts on the thermistor. If there is an open circuit and your multimeter reads “OL” or infinite resistance, it means the thermistor is faulty and needs to be replaced.
5. Remove and replace the faulty thermistor: If the continuity test confirmed that the thermistor is faulty, carefully disconnect the wires attached to it and remove it from the heater assembly. Replace it with a new thermistor specifically designed for your Whirlpool dryer model.
6. Reassemble and test: Once the new thermistor is installed, reassemble the back panel of your dryer and plug it back in. Turn on the power and run a test cycle to ensure the F42 error code is no longer present.

By following these steps, you should be able to fix the F42 error code on your Whirlpool dryer and have it working like new again. However, if you are unsure of your repair skills or the problem persists even after replacing the thermistor, it is always recommended to seek the assistance of a professional technician. They have the knowledge and tools to diagnose and solve complex issues with your appliances.

Remember, a little troubleshooting and some DIY skills can save you time and money. So don’t panic when you encounter the F42 error code on your Whirlpool dryer. Take a deep breath, grab your tools, and follow the steps outlined above to get your dryer up and running smoothly once again!
