Remote Works but the Wall Switch Doesn’t

This is one of the most common problems with every Liftmaster Garage Door Opener unit. You may wonder that the remote response, but the wall switch doesn’t. This is probably because the wall switch may have a faulty unit or wiring.

  • Replace the wall switch and wires to fix this problem. You may need to replace either the wall switch or the switch wires.
  • Start with troubleshooting the problem to determine whether the switch or the wires are bad.
  • Unscrew the switch from the wall and touch the two inner wires together. If the opener runs, you may have a bad switch unit. It’s easy to replace the wall switch unit. Consider getting a new opener that has a light and a locking option on the switch.
  • If you touch the two wires and the opener doesn’t run, the problem is with the wires. To further diagnose the problem, use a small wire and jump the two wires at the opener terminal; the opener would probably run. The staples that hold the wire to the wall pinch can cause a short circuit. As a solution, you can replace the wire and install 18 to 22 gauge wire.

Wall Switch Works But the Remote Doesn’t

If the wall switch works but the remote doesn’t, the problem is with the remote unit or its batteries. Consider replacing the remote batteries before finding other solutions. If the remote works after replacing batteries, then you’re good to go.

  • If your remote doesn’t work even after replacing batteries, you should consider replacing the remote unit. The older remote, after continuous pressing, can lose its grip. The best option is to replace it altogether. You’d need to replace the receiver too that will change the radio frequency. This is good because it will automatically update the older opener with new rolling code technology.

The Garage door only goes down when you hold Down the Wall Switch

This is a relatively rare problem with Liftmaster garage door openers. When your garage door easily opens but only goes down when you hold down the wall switch, the problem is with the safety sensors. When the safety sensors aren’t in alignment, it will prevent the garage door from closing.

  • You can manually adjust the sensor’s alignment by checking if both the red “Source” and green “Sensor” light bulbs are working fine. Check if one or both of the lights are off, and then check for faulty fuses, breakers, and plugs for problems. Consider replugging the power source to reboot the sensor.
  • The photo eye sensors may need adjustments or realignment to fix the sight path. Ensure nothing is blocking the light between the electronic photo eye sensors. Clean the photo eye sensors with a microfiber cloth to remove debris from blocking the light.

Everything works fine except the lights

Every new Liftmaster garage door opener units come with corner-to-corner LED lighting. If everything works but lights, then you must have the wrong light socket.

  • Start with checking if the bulbs are OK. You’d need to replace the socket to solve this problem. Remove the circuit board from the motor unit to replace the socket that holds the light bulb and wire terminals. Use a 1/4-in. nut driver to open the screw.
  • Once you open the circuit board, remove the old socket and two wires by depressing the clip that holds it in place. Replacement socket may cost less than $15.

Remember to use the bulb with the correct wattage. Using light bulbs with higher wattage can cause sockets to fail and cause a fire in rare conditions.
