Haier Dryer starts on its own

If your Haier dryer starts on its own, the fault is usually with an electrical control rather than the motor or drum. The most likely culprit is a bad motor relay, which can close the circuit and start the dryer without user input; next to check is the timer, which can send unintended start signals. If those test good, the problem often lies with the main control board or other control board components, which can short or fail and energize the motor. Less commonly a faulty touchpad, user control or display board will behave intermittently and effectively act like a stuck start button. You can test the motor relay and timer with a multimeter and inspect control boards for burning or shorted components, and replacing a defective user control assembly will stop random starts when the start button is acting up. Enter your model number on RepairClinic.com to find the exact replacement motor relay, timer, control board, or touchpad that fits your dryer and get step by step parts and repair guidance.

01 - Haier 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.)

04 - Haier Dryer Main Control Board

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 - Haier 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.

06 - Haier Dryer User Control and Display Board

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.
