Whirlpool Dryer Error Code F:25

When your Whirlpool dryer displays Error Code F:25, it means that the control system has detected an electrically shorted inlet thermistor, which is essentially a temperature sensor. Resolving this issue is crucial to ensure your dryer operates efficiently. Here’s a detailed guide on how to diagnose and troubleshoot this error:

1. Safety First:

• Before you begin any troubleshooting, safety should be your top priority. Unplug the dryer from the electrical outlet to ensure your safety during the inspection and repair process.

2. Locate the Inlet Thermistor:

• In most Whirlpool dryers, the inlet thermistor is combined with the high-limit thermostat. You’ll find this component attached to the heating element housing, often accessible through the rear panel of the dryer. Consult your dryer’s user manual for the exact location.

3. Check the Thermistor’s Resistance:

• To determine if the inlet thermistor is defective, you’ll need to measure its resistance. A functioning thermistor typically reads around 50,000 ohms at room temperature.
• Use a multimeter to measure the resistance. Set the multimeter to the ohm (Ω) setting.
• Disconnect the wires connected to the inlet thermistor to isolate it from the circuit.
• Place the multimeter leads on the thermistor’s terminals. It’s essential to measure the resistance at room temperature (approximately 77°F or 25°C).
• If the resistance reading significantly differs from the expected 50,000 ohms, it indicates a faulty thermistor, and it should be replaced.

4. Replacement of the Inlet Thermistor:

• If the inlet thermistor is found to be defective, you will need to replace it. Ensure that you have the correct replacement part for your specific Whirlpool dryer model.
• Carefully follow the instructions provided in your dryer’s user manual or consult a professional technician if you are unsure about the replacement process.

By following these steps, you can diagnose and address Error Code F:25 on your Whirlpool dryer. However, if you’re uncomfortable with the troubleshooting process or need assistance with part replacement, it’s advisable to contact a professional appliance repair technician. They can ensure a thorough and safe resolution to the issue, getting your dryer back in working order.
