1. First, check for power. Make sure the power supply hasn’t been disrupted by verifying the motor is plugged in. Also, check the circuit breaker, fuse or Ground Fault Circuit Interrupter.

2. If a power disconnect doesn’t seem to be the problem, look into the remote.

  • You may be out of range and need to move closer to the garage.
  • The antenna on the motor unit should be hanging down.
  • Replace the battery in the remote if the unit functions properly when using the wall switch.
  • Try reprogramming the remote.
  • Still no luck? You may need a new remote.

3. You may want to check the safety sensors for an obstruction or misalignment. An object in your garage may be interfering with the path of the laser beam. This will disengage operation of your door. Sometimes these sensors can get bumped and throw off alignment of the sensors which will cause your garage door opener to disengage operation too.

4. If the garage door will not open or close properly, Limit controls can be adjusted to ensure complete opening or closing. The limit switch may also be responsible if the door reverses immediately after hitting the floor or if the door opens but the motor won’t stop running.

5. Keep in mind that the hardware connecting the operator to the door can become loose over time and may affect the smooth operation of the door. It is important to periodically check and tighten this hardware before it becomes a safety hazard.

6. Another good maintenance practice is to lubricate the traveling mechanism of the garage door operator. This will minimize excessive noise and extend it’s operating life considerably.
