Gaggenau Dryer starts on its own

If your Gaggenau dryer powers up or starts running on its own, the most likely culprit is a failed motor relay that sends power to the motor when it should not; check that first. Next most common causes are a faulty timer or faults on the control board or main control board, which can close circuits at the wrong time. Less likely but still possible are problems with the touchpad or user control and display board, especially if the start/cancel button is intermittent — that will make the dryer behave like the dryer start button not working or the dryer controls not responding. Before swapping parts, verify the symptom with a multimeter and the wiring diagram, inspect boards for burned components, and rule out simple issues with the touchpad. If testing confirms a failed relay, timer, or control board, replacement will stop the random starts. Enter your model number on RepairClinic.com to see the exact replacement motor relay, timer, control board, or touchpad that fits your dryer.

01 - Gaggenau Dryer Motor Relay

If the dryer touchpad is working appropriately, it's possible the motor relay is defective. However, this is not that common of a problem. Before replacing the motor relay, check all the more commonly defective parts. If you determine that all of the other components are working properly, you can test the motor relay by using a multimeter and consulting the wiring diagram to help determine if it is malfunctioning.

If the dryer touchpad is working appropriately, it's possible the main control board is defective. However, this is not that common of a problem. Before replacing the board, check all of the more commonly defective parts. If you have determined that all of the other components are working properly, replace the main control board. (The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component.)

05 - Gaggenau Dryer Touchpad and Control Panel

If the dryer's start/cancel button is only working intermittently, it's likely the user control and display board is malfunctioning and causing the dryer to start running. A new board will need to be installed to resolve the problem.
