If your ThinAir dryer is not functioning properly, and you have determined that the issue may be the motor, don’t worry! With the right tools and a little know-how, you can replace the motor yourself. In this blog post, we will provide you with a detailed step-by-step guide on how to replace the motor on your thin air dryer. So, let’s get started!

Step 1: Disconnect Power to the Unit

The first step to replacing the motor on your ThinAir  dryer is to ensure that there is no power running to the unit. You can do this by disconnecting the power source to the dryer.

Step 2: Remove the Cover

Remove the cover by removing the tamper-proof bolt located on the bottom of the dryer. Gently lift the cover upwards to remove it.

Step 3: Disconnect Wires from the Motor

Check for power to the unit, and then disconnect the wires from the motor. To do this, remove the black wire from the low side of the terminal block followed by the white wire.

Step 4: Remove the Dryer Pre-Filter and Blower Housing

Remove the dryer pre-filter, and then locate and remove the six screws which hold the blower housing front. Once the screws are removed, grasp the motor along with the bottom muffler housing output, and remove the old motor.

Step 5: Replace the Motor

Replace the motor followed by replacing the top and bottom mufflers. Route the white and black wires from the motor through the notch in the blower housing front and press in place to the notch in the blower housing back. Secure with the six screws.

Step 6: Reconnect the Wires

Reconnect the white wire from the new motor to the white connector, and the black wire to the low side of the terminal block where previously removed.

Step 7: Reinstall Cover and Test Dryer

Replace the pre-filter, reinstall the cover and the cover screw, and return power to the dryer. Test dryer for proper operation by operating for more than 10 seconds.
