H0021800035WA Genuine Motor Controller Board for Haier Appliances

Part H0021800035WA is Haier's genuine motor controller, the electronic module that drives and regulates a motor. Our record for this number doesn't name a model or appliance, so the part number is the key to getting it right. Read the label on your existing controller, or send us your appliance's model number and we'll check whether this is the match before you order.

Signs of a failing Haier motor controller

A motor controller takes instructions from the main control board and turns them into the power the motor needs, adjusting its speed and, where needed, its direction as the program calls for. When it fails, the motor may not turn at all, may jerk or run at the wrong speed, or the appliance may stop mid cycle and show a motor or communication error. Scorch marks, a burning smell or swollen components are telltale signs. Check the motor, its wiring and plugs before replacing the controller, since a shorted motor can damage a new board.

Replacing the controller

Unplug the appliance and wait several minutes before opening it, as controller boards can hold a charge. Photograph every plug and earth connection, and handle the new board by its edges to avoid static damage. Make sure each connector clicks fully home, then run a test cycle while watching for any error codes.

Questions about this part

Will a controller with a similar number work?

Not reliably. Haier controllers that look alike can carry different software or connectors for different models. Only order H0021800035WA if your existing board or your appliance's parts information shows this exact number, or once we've confirmed it from your model number.
