GE Dryer Error Code E08

The E08 error code on a GE dryer indicates a door latch stuck condition within the hardware door switch detection circuit. Specifically, the control board has monitored the door switch signal across five consecutive drying cycles and has not detected the circuit opening, which would normally occur when the door is unlatched and opened between cycles. The door switch is part of a safety and operational detection circuit that tells the main control board whether the door is open or closed. When the board expects the door to open but never receives that signal, it flags E08 to alert the user and technician to a fault in this circuit.

The three primary components involved in this fault are the door switch itself, the wiring harness connecting the switch to the main control board, and the main control board. The door switch is a mechanical component that can fail in a closed or shorted position, meaning it continuously sends a closed-circuit signal even when the door is physically open. This is the most common cause of E08. A damaged or pinched harness can also cause a persistent closed signal to reach the board. In rarer cases, the main control board itself may be misreading the incoming signal from an otherwise functional switch.

Diagnosis should begin by opening the dryer door and checking whether the fault clears. If E08 persists after the door is opened, the switch is likely failed in the closed position or the harness is compromised. Testing the door switch with a multimeter for continuity in both the open and closed door positions will confirm whether the switch is operating correctly. If the switch and harness test within specification, the main control board should be considered as the root cause and replaced.
