Garage Door Opener Troubleshooting

A garage door opener is a motorized device that enables the owner to open and close a garage door. It is controlled by switches on the garage wall or by a remote control. A garage door should be convenient to use, quiet and dependable. Sometimes, even with the best employed system and regular maintenance, garage doors break down. This could cause owners to have questions regarding safety, maintenance and cost.

Read below where Experts have answered questions relating to garage door opener problems.

What could be the issue if the garage door opener operates on its own?

A defective remote, a short in the wiring between the wall button and the opener or a defective wall button could cause the door to open on its own. Erasing all the codes from the remote by holding the LEARN button for 5-10 seconds and reprogramming the remotes could help resolve the issue. Rewiring, replacing the wall button and removing batteries from all remotes and keyless pads could fix the issue of self-opening.

How can one manually open the door with a Lift master 1/3 HP garage door opener which has one of its springs broken?

If the springs are broken, one needs to get help from two strong people to lift each side of the door. Another person needs to insert pieces of lumber measuring 2x4 in length under each end of the door and thereby slide it open. The type of springs to be used to replace the broken springs would be determined by the technician as there are springs of varied types. The broken springs should be replaced by a professional who is experienced in this field as the tension on the new spring could prove dangerous to an inexperienced person attempting to change it.

What could be the problem if the door closes only if the wall button is held down in a craftsman garage door opener?

This could be due to bad safety sensors or due to an obstruction between the safety sensors, condensation, dirty eyes, breakage of wires to the sensor and loose wires at the sensors or at the motor head. A red light instead of a green light or only one sensor light would be blinking in the event of a defect in the safety sensors.

To fix this issue, one would need to clean the eyes on the sensor, direct the eyes at each other and fasten the wire connections at the sensor and motor head securely. In order to reset the sensors, the garage door opener could be unplugged and plugged back into the outlet. For the breakage of the wires to the sensor, the wires need to be stripped off the plastic, twisted and taped together with electrical tape. If none of the above fixes the issue, then the sensors need to be replaced.

What could cause a craftsman garage door opener to stop after opening about 8 inches and has its lights blinking?

The blinking of lights could be indicative of a blocked path not necessarily in the literal sense that there is something blocking the eyes on the sensor. Even a minor friction along the track or misalignment on account of loose screws on the door panels could signal the circuit board (motherboard) to stop.

To check this, the screws and bolts on the door and track brackets need to be tightened, wire connections need to be fastened at the sensor securely and the wheels need to be lubricated with silicone or any other issues like a bowed track needs to be checked upon.

If all the stated checklists are clear, then it is an indication that the motherboard is giving out incorrect signals and needs to be replaced.

What could be done if a remote with new batteries works only when held close to the opener of a craftsman garage door?

  • Erase all codes and reprogram the remotes by following the manual.
  • Unplug and plug back the motor unit for a reset.
  • Check to see if the antenna has been fixed in the right direction and if it has been secured to the circuit board.
  • Next, check for a burnt solder connection on the board or a solder defect at the antenna.
  • If this is the issue, then the circuit board would require replacement.
  • A remote could also have range problems on account of satellite dishes, cell towers or wireless devices that may have been installed recently in the house.
  • In such a case, unplugging the device could help to see if the remote works.
  • Finally, using an extension cord to plug in the garage door opener into a different circuit could fix this issue.

The availability of garage door openers have increased and more sophisticated features have been made available over the years. Excellences in terms of quality and safety have been introduced to ensure there are no casualties in the event of an emergency. However, there could be issues that may require guidance. When questions arise turning to an Expert for help may prove to be useful.
