What hE means on a Amana dryer

The hE error code on an Amana dryer indicates a heating error caused by an invalid heating temperature detected while the dryer is actively running. The control board monitors temperature through a thermistor and expects the drum temperature to rise and stabilize within a defined range during a cycle. When the sensed temperature falls outside acceptable parameters, whether too low due to inadequate heat or too high due to restricted airflow, the board flags the hE fault and may halt or limit the heating element's operation.

The two primary areas to investigate are the vent system and the thermistor itself. A restricted or blocked exhaust vent is one of the most frequent causes of heating errors in dryers. When airflow is reduced, heat builds up abnormally and the thermistor reports temperature readings that fall outside expected thresholds. Lint accumulation in the vent line, a crushed duct behind the unit, or a clogged exterior vent cap can all produce this condition.

The thermistor is a resistive temperature sensor whose resistance value changes predictably with temperature. If the thermistor has drifted out of calibration, developed an open circuit, or has a wiring harness fault such as a loose connector or damaged lead, the control board receives a signal that does not match expected temperature behavior. This can trigger the hE code even when the vent system and heating element are functioning correctly. Checking thermistor resistance with a multimeter and comparing it to the specified range is a key diagnostic step.

Common causes of hE

  1. 01

    Restricted or blocked exhaust vent

    Wiring / connection

    Lint buildup in the vent duct, a kinked flexible hose, or a blocked exterior vent cap reduces airflow and causes abnormal temperature readings. Disconnect the vent and run the dryer briefly to check if airflow improves.

  2. 02

    Faulty thermistor

    Part replacement

    The thermistor can fail by going open-circuit, short-circuit, or drifting out of its correct resistance range, causing the control board to read an invalid temperature. Test the thermistor with a multimeter and replace it if resistance readings are out of spec.

  3. 03

    Wiring harness issue at thermistor connector

    Wiring / connection

    A loose, corroded, or damaged connector at the thermistor or along its wiring lead can produce erratic voltage signals that the board interprets as an invalid temperature. Inspect the connector and wiring for damage, corrosion, or disconnection.

  4. 04

    Failed heating element

    Part replacement

    If the heating element is open or partially burned out, the dryer cannot generate adequate heat and the thermistor never registers expected temperature rise, triggering the hE code. Verify continuity across the heating element with a multimeter.

  5. 05

    Faulty control board

    Part replacement

    If the thermistor, wiring, vent system, and heating element all test correctly, the control board itself may be misreading the thermistor signal due to a component failure on the board. Control board replacement is typically a last resort after other components are ruled out.

Frequently asked questions about hE

What does hE mean on a Amana dryer?
The hE code on an Amana dryer stands for heating error. It means the control board detected an invalid temperature reading from the thermistor while the dryer was running. This can be caused by a blocked vent system, a failed thermistor, or a wiring problem. The dryer may reduce or cut off heat until the issue is corrected.
Can I fix the hE error on my Amana dryer myself?
Some causes of the hE code are DIY-friendly. Cleaning a clogged lint trap, clearing a blocked exhaust vent duct, or reseating a loose thermistor connector are tasks most homeowners can handle safely. Testing and replacing the thermistor requires a multimeter and basic appliance repair skills. Heating element and control board replacements are more involved but are within reach for experienced DIYers.
Is it safe to keep running my Amana dryer with the hE error showing?
It is not recommended to continue running the dryer while the hE error is active. A restricted vent is a fire hazard because trapped heat and lint can ignite. A faulty thermistor means the control board cannot accurately monitor temperature, which removes a key safety layer. Diagnose and resolve the error before resuming normal use.
Will resetting my Amana dryer clear the hE error code?
A power reset, such as unplugging the dryer for a few minutes, may temporarily clear the hE code, but it will return if the underlying problem has not been fixed. The error is triggered by an active fault condition, so the code will reappear once the dryer runs and the control board detects the invalid temperature again. A reset is useful for confirming whether the fault is intermittent but should not be used as a substitute for diagnosis.
How much does it cost to repair an Amana dryer with the hE error?
Repair costs depend on the root cause. Vent cleaning is typically low cost, ranging from no cost if done yourself to around $75 to $150 for professional duct cleaning service. A replacement thermistor is generally an inexpensive part, with total repair costs often falling in the $50 to $150 range including labor. A heating element or control board replacement tends to be more costly, with professional repair estimates typically ranging from $150 to $350 depending on the part and local labor rates.
