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

Technical Background:

The dryer's Main Control Unit (MCU) monitors the heater circuit. The 'hE' error indicates the MCU detects an unexpected voltage or current reading in the heater element circuit, often pointing to a fault with the heater, its associated components, or the wiring. The MCU relies on feedback from thermistors and thermostats to manage the heating cycle. Voltage to the heater is typically 240V AC in the US.

Symptoms:

The dryer displays the 'hE' error code and does not heat. The drum may still tumble, but clothes remain wet after a cycle. You might notice a burning smell if the heater element is shorted.

Possible Causes:

Open or shorted heater element.
Faulty heater relay on the control board.
Wiring harness issue between the control board and the heater element.
Tripped thermal fuse or thermal cut-off.
Failed high-limit thermostat.
Blocked exhaust duct restricting airflow.

Solution:

1

Disconnect power to the dryer at the breaker panel. Verify 0V AC at the dryer receptacle using a multimeter.
2

Locate the heater element housing at the back of the dryer. Remove the rear access panel using a 1/4-inch nut driver.
3

Disconnect the wires from the heater element and test for continuity using a multimeter. Resistance should typically be between 9-15 ohms. An open circuit indicates a failed heater element.
4

Check the thermal fuse and high-limit thermostat (located on the heater housing) for continuity. Use a multimeter set to continuity testing. Replace if open.
5

Inspect the wiring harness for any damage or loose connections. Pay close attention to the connectors at the heater element, control board, and thermostats. Repair or replace as needed.
6

If the heater element, thermal fuse, and wiring are good, suspect a faulty heater relay on the control board. Visually inspect the board for burned components. Replace the control board.
7

After repairs, reconnect power and test the dryer operation. Monitor the heater element for proper heating. Check the exhaust temperature with a thermometer; it should gradually increase.

Safety Warning:

Disconnect power to the dryer at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures are recommended to prevent accidental energizing of the circuit. The dryer operates on 240V AC, which can be lethal.

Prevention:

Clean the lint filter after every load to ensure proper airflow. Regularly inspect and clean the exhaust duct to prevent blockages. Avoid overloading the dryer, which can strain the heating system.

Expert Tip:

Some Amana dryers have a diagnostic mode. Consult the service manual for your specific model to access it. The diagnostic mode can provide more specific error codes or allow you to test individual components, such as the heater relay. Often you can initiate this mode by pressing and holding specific buttons simultaneously while powering up the dryer.

Frequently Asked Questions

•What is the resistance range I should expect on a good heater element?

A typical heater element should read between 9 and 15 ohms. Anything outside this range indicates a likely problem.

•Where is the thermal fuse located and how do I test it?

The thermal fuse is usually located on the heater housing. To test it, disconnect power, remove the fuse, and use a multimeter set to continuity. A good fuse will show continuity (a reading of 0 ohms or a beep). An open fuse will not show continuity.

•If the heater element and thermal fuse are good, what else could be causing the 'hE' error?

If the heater element and thermal fuse are good, the problem likely lies with the high-limit thermostat, the wiring harness, or the control board itself. Check the thermostat for continuity and the wiring for damage. If both are fine, the control board may be faulty and require replacement.
