How to Fix E12 Error

UNPLUG THE DRYER IMMEDIATELY. This error means the heater relay on the main control board is stuck in the closed (on) position, which is a serious fire hazard.
The relay is a non-serviceable part of the main control board.
The only safe and correct repair is to replace the entire main control board.
Follow the procedure for code F01: Locate the board, photograph the wiring, label and disconnect all harnesses, swap the board, and carefully reconnect all wires.
