    Hi Brian,
    If this is a new installation then I would double check the wiring.
    See How to Test Electrical Wiring, and check the switch wiring, compared to the switch wiring diagrams section.
    If this is an existing unit then I would check the motor paying special attention to the blower where dust can accumulate and cause the motor to spin slower and overheat. Pull out the fan blower assembly unit, clean and lubricate as specified.
