Whirlpool Dryer Error Code F:22

If your Whirlpool dryer displays the error code F:22, it signifies that the control panel has detected an electrically open outlet thermistor, which is essentially a temperature sensor. This issue can impact the dryer’s ability to regulate temperature effectively. Here’s a more detailed explanation of the error and steps to address it:

What Does F:22 Error Mean?

The F:22 error code indicates that the thermistor, responsible for measuring the temperature inside the dryer, is not providing the expected electrical resistance. This can affect the dryer’s performance and its ability to maintain the desired temperature during the drying process.

Troubleshooting Steps:

To address the F:22 error, follow these steps:

a. Safety First: Ensure the dryer is unplugged from the power source before conducting any checks or repairs.

b. Locate the Thermistor: The thermistor is typically found near the dryer’s blower housing. Refer to your dryer’s manual for the exact location.

c. Check Resistance: Use a multimeter to measure the electrical resistance of the thermistor. A functional thermistor should have a resistance of about 10,000 ohms at room temperature.

d. Replace the Thermistor: If the resistance measurement deviates significantly from the expected 10,000 ohms or shows as “open” (infinite resistance), it indicates a defective thermistor. In such cases, the thermistor should be replaced.

Replacing the Thermistor:

When replacing the thermistor, follow these steps:

a. Obtain a compatible replacement part from a reputable supplier or the manufacturer.

b. Disconnect the wiring harness attached to the old thermistor.

c. Carefully remove the old thermistor from its housing.

d. Install the new thermistor and secure it in place.

e. Reconnect the wiring harness.

Testing:

After replacing the thermistor, plug the dryer back in and run a test cycle to ensure that the F:22 error has been resolved and the dryer is operating at the desired temperature.

If you’re uncomfortable or unsure about performing these checks and replacements, it’s advisable to seek assistance from a professional appliance repair technician. They can diagnose the issue, replace the faulty part, and ensure that your Whirlpool dryer operates efficiently once more.
