RESOLUTION
Turn off power to control box and make sure safety eyes are not blocked, open button is not stuck in, car wash controls are not sending an open signal. Turn power back on. If error code is still present, contact Airlift Technical Assistance.
Determine reason for low incoming voltage. Supply voltage to control boxmust be 110v-120v.
Check counterweight system (Premium model only). With thedoor in the open position, the counterweight strap should be completelyunwound with the weights towards the bottom of the guide tube. Check thatthe strap is not frayed or broken. Replace strap and/or adjust weights as necessary. Consult installation manual for proper weight adjustment.
Make sure there are no loose bolts, worn bearings, ice, or any other obstructionpreventing the door from traveling properly in the track. Also make sure doorroll has not shifted to one side and is rubbing against either bearing plate.
If counterweights and obstructions have been ruled out, the motor may beexcessively worn. Consult with factory for troubleshooting.
