Whirlpool Dryer Error Code F01 — Main Control Board Failure
What this means
The F01 error code on Whirlpool dryers indicates the main electronic control board has an internal failure. This is a common error on Whirlpool Duet and Cabrio dryer models. The code typically appears due to a power surge damaging the board's relay or processor, or from component degradation over time. The dryer will not start or will stop mid-cycle when this code appears.
Alternate codes: F1
Step-by-step fix
4 stepsPower cycle the dryer
Unplug the dryer or turn off the circuit breaker for at least 5 minutes. Restore power and try running the dryer. If the code clears, a temporary glitch was the cause.
If you recently had a power outage, the board may just need a full reset.
Access the control board
Unplug the dryer. Remove the top panel (2 screws at the rear on most models). The main control board is typically located at the top rear of the machine inside a housing box. Remove the housing cover.
Take a clear photo of all wire connections before disconnecting anything.
Inspect for visible damage
Look at the control board for burned components, darkened areas on the circuit board, or swollen capacitors. Also check that all wire connectors are firmly seated.
A solder joint that has cracked can sometimes be re-soldered by an electronics-savvy person as a temporary fix.
Replace the main control board
If the board shows damage or the error persists, replace the control board. Transfer all wire harnesses from the old board to the new one, matching connector positions exactly.
Install a surge protector on the dryer outlet to protect the new board.
When to call a professional
If you're not comfortable working with dryer electronics or if the new board doesn't resolve the issue, professional diagnosis is recommended.
