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

Technical Background:

The Roper dryer's main control unit (MCU) monitors the voltage and current flow through the heating element circuit. The 'hE' error code indicates that the MCU has detected an abnormal condition, such as an open circuit or a short circuit in the heating element or its associated components. The MCU uses a relay to supply 240V AC to the heater. Thermistors and thermostats provide feedback to the MCU.

Symptoms:

The dryer is not heating up or takes an excessively long time to dry clothes. The dryer may display an 'hE' error code on the control panel.

Possible Causes:

Open or shorted heating element
Faulty wiring harness or connections to the heating element
Defective high-limit thermostat
Failed thermal fuse
Tripped breaker or blown fuse in the home's electrical panel
Malfunctioning motor relay on the control board

Solution:

1

Unplug the dryer from the wall outlet.
2

Remove the rear access panel of the dryer using a 1/4-inch nut driver.
3

Visually inspect the heating element for any breaks, burns, or shorts.
4

Using a multimeter, test the heating element for continuity. A reading of approximately 10-50 ohms indicates a good element.
5

Check the thermal fuse and high-limit thermostat for continuity. Replace if open.
6

Inspect all wiring connections to the heating element, thermal fuse, and high-limit thermostat. Repair or replace any damaged wiring.
7

Check the voltage at the heating element terminals when the dryer is running (approximately 240V AC).

Safety Warning:

Disconnect power to the dryer at the breaker panel before performing any repairs. Use proper lockout/tagout (LOTO) procedures. The dryer operates on 240V AC, which can cause serious injury or death.

Prevention:

Clean the lint screen after every load. Regularly inspect and clean the dryer vent duct to prevent overheating and lint buildup, which can damage the heating element and related components. Have a licensed technician inspect your dryer annually.

Expert Tip:

Some Roper dryers have a diagnostic mode. To enter diagnostic mode, simultaneously press and hold the Start and Cancel buttons for 3 seconds. Error codes can be retrieved and cleared in this mode.

Frequently Asked Questions

•What should the resistance reading be across the dryer's thermal fuse?

A functional thermal fuse should have a resistance reading close to 0 ohms, indicating continuity. An open thermal fuse will have infinite resistance.

•If the heating element has continuity but the dryer still isn't heating, what else could be the issue?

Even with continuity, the element may have a partial short to ground, reducing its heating capacity. Also check the high-limit thermostat, motor relay on the control board, and incoming voltage (240V AC).

•How do I test the dryer's motor relay?

The motor relay can be tested for continuity when the motor is activated. If there is no continuity, the relay needs to be replaced. Relays are usually located on the control board. You may also hear a clicking sound if the relay is working.
