Electrolux Dryer Error Code E68 — Heater Relay Stuck Closed on Control Board
What this means
The E68 error code on Electrolux dryers is a safety alert indicating the heater relay on the main control board has welded shut (stuck closed). This means the heating element could remain energized even when the board commands it off, creating a fire risk. The dryer will refuse to operate when this code is active. The control board must be replaced.
Alternate codes: E 68
Step-by-step fix
4 stepsStop using the dryer immediately
Do not attempt to run the dryer with this error code. A stuck heater relay means the heating element could stay on continuously, which is a fire hazard. Turn off the circuit breaker.
This is one of the few error codes that should never be ignored or bypassed.
Confirm the error by checking the heating element
With the breaker off, use a multimeter to check continuity between the heater relay output terminals on the control board. If there is continuity even with the board powered off, the relay is welded shut. This confirms the E68 diagnosis.
Do not attempt to run the dryer to see if the heater stays on — the safety risk is not worth the test.
Replace the main control board
Turn off the breaker. Remove the top panel and locate the main control board (usually mounted on the left or right side). Disconnect all wire harness connectors (photograph them first), remove the mounting screws, and install the new board.
Transfer any settings or configuration labels from the old board to the new one if applicable.
Test the dryer
Restore power and run a timed dry cycle. Verify that the heater turns on and off appropriately during the cycle. Monitor the first cycle closely.
If the dryer heats normally and stops heating when the target temperature is reached, the repair is successful.
When to call a professional
Given the fire safety risk, if you are not confident in the diagnosis or the board replacement, have a qualified technician handle this repair.
