You will need to test the wiring to determine if the Lift Motor # MA10-20270 is getting power when you press the remote. This will help you determine if the motor is bad or the Printed Circuit Board # MA10A04751KS on your MaxxAir fan.

A Test Light # PTW2993 will allow you to check the wiring without having to disconnect the wiring.
