PROBLEM #1: Garage Door Remote Doesn’t Work
If the garage door opens and closes properly using the wall switch, the garage door remote control is obviously not working. Check the remote by holding it within range of the garage door opener. Is the remote battery down? Check the battery in your remote operator by pressing the button while walking towards the door and check for a small blinking red light on the box where the chain enters and exits. If the door opens as you get very close to the box, but fails to open as you back away, the battery is low and needs to be replaced. If there’s no blinking red light, the battery is dead. Try to replace the batteries and check. Still not working? You might need a new garage door remote that’s compatible with your garage door opener.
PROBLEM #2: Door Doesn’t Open with Remote or Wall Switch
If your garage door does not open with both remote or wall switch, check for power connections. Is the garage door opener unit receiving power, and in the right voltage. Check for loose electrical connections, circuit breaker, fuse or ground fault circuit interrupter (GFCI) to determine whether there is any electrical problem.
If the garage door opener won’t work, use the emergency release chain to disengage the opener system and allow the garage door to function manually as a short-term solution.
PROBLEM #3: Door Doesn’t Close Fully or Reverses
Inspect the close limit switch and try re-adjustment. If this doesn’t fix the problem, get professional assistance.
PROBLEM #4: Garage Door Opener’s Motor Continues to Run
Check the close limit switch and try adjustment. Try moving it away from the garage door opener motor unit.
PROBLEM #5: Door Reverses Before Touching the Floor
Check for any possible obstruction blocking the door’s smooth close. Adjust the close force.
PROBLEM #6: Garage Door Sticks when Opening or Closing
If the garage door sticks, it requires lubrication. Check if the metal rollers and hinges probably needs lubricating. The garage door tracks may also be dirty, clogged or out of alignment. So, clean the tracks for any obstruction.
Problem #7: Garage Door Won’t Close All the Way
The garage door close limit switch needs adjusting. See if the door is binding when operated manually.
Problem #8: Garage Door Reverses Immediately After Hitting Floor
Once again, the close limit switch probably needs to be re-adjusted for proper functioning. It might also require checking the close force and re-adjusting it.
Problem #9: Garage Door Doesn’t Open Completely
The open limit switch probably needs to be readjusted. Ask for assistance from a trained garage door technician.
Problem #10: Photo Eye Out of Alignment
On either side of your garage door are photo eyes that serve as sensors. Between the two photo eyes is an invisible beam that serves as a safety measure. When the two photo eyes cannot create one single unbroken beam, it prevents the garage door from closing. If your door won’t close, check if these photo eyes are misaligned or dirty. Clean the photo eyes for any dirt. If it is misaligned, you will have to fix it in place again.
