Admiral Dryer Error Code hE: Heater Element Circuit... | appliancefaults.com

Technical Background:

The MCU (Microcontroller Unit) on the dryer's control board monitors the heater element circuit. It expects to see a certain resistance range. When the resistance falls outside this range, or an open circuit is detected, it triggers the hE error, indicating a potential fault within the heating circuit. Voltage is typically 120V AC from the breaker panel through the control board to the heater element.

Symptoms:

The dryer is running, but not producing heat. The hE error code is displayed on the control panel.

Possible Causes:

Open heater element
Faulty heater relay on the control board
Wiring harness issue (open or short) in the heater circuit
Defective thermistor or high-limit thermostat
Blocked vent causing overheating

Solution:

1

Disconnect power to the dryer at the breaker panel.
2

Access the heater element housing, typically located at the rear of the dryer. Use a 1/4-inch nut driver.
3

Inspect the heater element for any breaks or visible damage. Use a multimeter to test for continuity across the element terminals. An open circuit indicates a failed element.
4

Check the high-limit thermostat and thermistor for continuity. These are often located near the heater element. Replace if open.
5

Inspect the wiring harness connecting the heater element, thermostat, and control board for any loose connections or damage. Repair or replace as needed.
6

Test the heater relay on the control board. If possible, check for proper voltage (120V AC) to the relay when the dryer is calling for heat. Replace the control board if the relay is faulty.
7

Clear any lint buildup from the venting system to ensure proper airflow.

Safety Warning:

Disconnect power to the dryer at the breaker panel before performing any repairs. Use proper Lock Out Tag Out (LOTO) procedures. The dryer uses 120V AC, which can cause serious injury or death.

Prevention:

Clean the lint filter after every load. Inspect and clean the dryer vent annually to prevent lint buildup and overheating.

Expert Tip:

Some Admiral dryers have a service mode. Entering service mode (refer to the service manual) allows you to run diagnostic tests on individual components, including the heater element circuit.

Frequently Asked Questions

•How do I access the heater element on my Admiral dryer?

Typically, you'll need to disconnect power, remove the rear access panel using a 1/4-inch nut driver. The heater element housing will be visible. Be careful when disconnecting wires.

•What resistance value should I expect to see on a good heater element?

A typical heater element resistance is between 8 and 12 ohms. An open circuit (infinite resistance) indicates a bad element.

•How do I know if the control board is faulty?

After checking all other components, if the heater relay on the control board is not sending voltage (120V AC) to the heater element when the dryer calls for heat, and all wiring is good, the control board is likely faulty. You can check the relay with a multimeter while the dryer is calling for heat (use caution!).
