Lift Not Working

Problem: When the furnace is turned on, the lift doesn’t move

Determine the cause

  • Check if motorĀ is bad ( IF furnace shuts down by itself, remove motor connector and turn furnace on)

  • Check if controller is bad.

Best way is to replace the controller card and fix the card later. These two relays are for motor. If the lift is stuck and the motor is drawing too much electric, the relays can jam.
