To program additional remotes, locate the "Learn" button on the back or side of the motor unit. Press the "Learn" button until the indicator light starts blinking. Within 30 seconds, press the button on the remote you wish to program. The indicator light will stop blinking when the remote is successfully programmed.
First, check the batteries in the remote control. If the batteries are fine, try reprogramming the remote. If the problem persists, check for any obstructions or misalignments in the sensors, and ensure the opener is receiving power.
Locate the force adjustment dials on the motor unit. Use a flathead screwdriver to turn the dials clockwise to increase the force or counterclockwise to decrease it. Adjust until the door opens and closes smoothly without reversing.
Regular maintenance includes checking and tightening hardware, lubricating moving parts, inspecting the door balance, and testing the safety reversal system. It's recommended to perform these tasks every six months.
To reset the opener, unplug the unit, wait about 30 seconds, and then plug it back in. This will reset the system. Note that you may need to reprogram remotes and keypads afterward.
This issue usually indicates that the travel limit is set incorrectly. Adjust the down travel limit by turning the appropriate screw on the motor unit until the door closes completely without reversing.
Yes, you can manually operate the door during a power outage. Pull the emergency release cord to disconnect the door from the opener, allowing you to open and close it manually.
Ensure the opener is unplugged. Remove the light lens cover by releasing the clips or screws. Replace the bulb with one of the same wattage and type, then reattach the lens cover and plug the opener back in.
Excessive noise can result from loose hardware, lack of lubrication, or worn parts. Tighten any loose bolts, apply lubrication to moving parts, and inspect for worn components that may need replacement.
Place a 2x4 board flat on the ground in the door’s path. Close the door using the remote. If the system is working correctly, the door should reverse upon touching the board. If not, adjust the down force or contact a technician.
