The E2 error code on a Whirlpool Duet dryer is an indication that there is an issue with the thermistor, a crucial component responsible for monitoring the dryer's exhaust temperature. When the E2 error code appears, it means that the thermistor has shorted, preventing the dryer from functioning correctly and potentially leading to unsafe operating conditions.

What is a Thermistor?

A thermistor is a type of resistor that changes its resistance with temperature fluctuations. In a dryer, the thermistor is used to monitor the temperature inside the drum and to ensure that the drying cycle is operating within safe temperature limits. It helps in regulating the heating element and the high-limit thermostat to maintain optimal drying conditions.

Causes of the E2 Error Code

The E2 error code typically occurs when the thermistor becomes shorted. This short circuit can be caused by various factors, such as physical damage to the thermistor, moisture buildup, or electrical faults within the dryer. A shorted thermistor fails to provide accurate temperature readings to the control board, causing the dryer to stop functioning to prevent overheating or other potential hazards.

Implications of a Shorted Thermistor

When the thermistor is shorted and the E2 error code is displayed, the dryer’s ability to regulate temperature is compromised. This can lead to various issues, including:

• Inconsistent drying: The dryer may not heat up properly, resulting in clothes that are either over-dried or still damp after the cycle.
• Safety risks: A malfunctioning thermistor can cause the dryer to overheat, posing a potential fire hazard if not addressed promptly.
• Cycle interruptions: The dryer may shut down mid-cycle as a safety precaution when the control board receives incorrect temperature data.

What to Do When You See the E2 Error Code
