Kenmore Dryer Error Code: F24 & F25

Kenmore dryers are renowned for their reliability, but like any appliance, they can encounter issues. If your Kenmore dryer displays error codes F24 or F25, it’s indicating a problem with the inlet thermistor, specifically an electrical open or shorted thermistor. In this article, we’ll delve deeper into these error codes and guide you through the diagnosis and solution.

Understanding the Error Codes:

• F24 Error: This code signals an electrically open inlet temperature sensor, which is essentially the thermistor.
• F25 Error: It indicates a shorted inlet temperature sensor or thermistor.

The Diagnostic Process:

When faced with F24 or F25 error codes, it’s crucial to diagnose the issue accurately. Here’s how you can go about it:

1. Power Down the Dryer: Before performing any diagnostic or repair work, ensure the dryer is disconnected from the power source to guarantee safety.
2. Use a Multimeter: A multimeter is a handy tool for measuring resistance. Set it to the resistance (ohms) setting.
3. Check the Thermistor: Locate the inlet temperature sensor, commonly known as the thermistor. Measure its resistance by touching the multimeter probes to the thermistor’s terminals.
4. Resistance Measurement: A functioning thermistor should display a resistance of approximately 50,000 ohms at room temperature. If the reading is significantly different, the thermistor is likely faulty and should be replaced.

Important Note: It’s worth noting that in many Kenmore dryers, the inlet thermistor is integrated into the high limit thermostat. Therefore, when replacing the thermistor, you may need to replace the high limit thermostat as well.

Replacement Process:

Once you’ve confirmed that the thermistor is faulty, it’s time to replace it. Follow these steps:

1. Obtain the Replacement Part: Ensure you have the correct replacement thermistor for your Kenmore dryer model.
2. Disconnect the Dryer: Unplug the dryer from the power source.
3. Access the Thermistor: Open the dryer’s access panel to reach the thermistor. It’s often located near the dryer’s heating element.
4. Remove the Faulty Thermistor: Carefully disconnect the wires attached to the thermistor and remove it from its housing.
5. Install the New Thermistor: Insert the new thermistor into the housing and reconnect the wires as they were on the old one.
6. Close the Access Panel: Secure the access panel back in place.

Kenmore dryer error codes F24 and F25 may seem daunting, but with the right diagnostic tools and a bit of guidance, you can tackle the issue. Keep in mind that safety is paramount, so always disconnect the dryer from the power source before performing any diagnostics or repairs. If you encounter any difficulties or if the issue persists, don’t hesitate to seek professional assistance. For more complex problems or concerns, it’s advisable to contact an experienced appliance repair technician. They have the expertise to address intricate issues and ensure your Kenmore dryer operates seamlessly.
