The F23 error code on a Whirlpool Duet Dryer indicates that the exhaust thermistor is shorted. The thermistor is a key component that monitors the exhaust temperature and helps regulate the dryer's heating element. When the thermistor is shorted, it can no longer accurately measure the temperature, which can prevent the dryer from heating properly or cause it to overheat.

When the F23 error code appears, it means that the machine control electronics have detected that the thermistor is providing a shorted signal. This typically results from a fault within the thermistor or its associated wiring, which can interrupt the dryer’s ability to function correctly and safely.

If you encounter the F23 error code, it's essential to address the issue promptly to avoid further damage to the dryer and ensure safe operation. A shorted thermistor can cause erratic dryer behavior and may lead to safety concerns if not resolved.
