Whirlpool Dryer Error Code hE

The hE code stands for Heating Error and means the dryer has detected an invalid temperature reading during a cycle. The control board monitors temperature through a thermistor, and when the reading falls outside expected parameters, it triggers this fault. Common causes include a blocked vent system, a faulty thermistor, or a failed heating element. Addressing it promptly is important to avoid poor drying performance or potential safety issues.

It is not recommended to continue using the dryer while the hE code is active. If a restricted vent is causing the fault, operating the dryer can create a fire hazard due to heat and lint accumulation. Even if the cause is a failed sensor rather than a venting problem, the dryer may not be heating correctly, which means clothes may not dry safely or efficiently. Diagnose and resolve the issue before resuming normal use.

Repair costs vary depending on the cause. Clearing a blocked vent yourself costs nothing beyond your time, while professional vent cleaning services typically run in the range of $75 to $150. Replacing a thermistor or high-limit thermostat is generally a lower-cost repair, with parts often ranging from $15 to $50 and labor adding $75 to $150 if a technician is involved. A heating element replacement or control board repair will fall on the higher end of the cost range.

Start by checking the exhaust vent for lint buildup, kinks, or blockages at the exterior termination point, as restricted airflow is a frequent cause of this code. Next, test the thermistor with a multimeter to verify it is producing resistance readings within the expected range for the current temperature. If the vent and thermistor are both in good condition, inspect the heating element and high-limit thermostat for continuity. Replacing the faulty component will typically resolve the error.

A reset may temporarily clear the hE code, but the fault will return if the underlying problem is not corrected. To reset, unplug the dryer or turn off the circuit breaker for about one minute, then restore power. If the code reappears after a short run time, the root cause, such as a blocked vent or a failed thermistor, still needs to be diagnosed and repaired.
