Merlin Garage Door Troubleshooting

In this topic of Merlin garage door troubleshooting, we’ll go over a few of the most common issues that users have and how to solve them…

How to reset the Merlin garage door after a power outage?

  1. First you must disconnect the garage door opener from the door itself. It’s best to unplug the opener from its power source beforehand.
  2. Pull the emergency disconnect cord hanging from the opener. This is the only way to disconnect the opener and allows you to fully open the door. This is especially important if you’re trapped in the garage.
  3. Manually close the door all the way. The opener will not reconnect properly if the door isn’t completely shut.
  4. After the power has been restored, press the button you typically use to close the door. Give the opener ample time to connect on its own. The chain of the opener will move the corresponding trolley to its correct position until it connects with the arm of the garage door.
  5. If the trolley of your garage door opener is not automatic, you will have to manually attach the trolley to the garage door’s arms after pulling the emergency release.

Your opener and door should be connected and functioning as good as ever!

To prevent further issues, consider investing in a surge protector for the outlet your garage door opener is plugged into.

Why won’t my remote open my garage door?

Remote Batteries Are Depleted: To check if your transmitter batteries are dead, try using your wall-mounted control panel to open the door — if the door responds, then dead batteries are likely the cause.

Remote Signal Disrupted: Stand within 20 feet of your garage door and attempt pressing the button — if your remote is further away from the door, the signal won’t be strong enough to prompt the door. If your remote works correctly, check that the opener’s antennae doesn’t have any excess debris buildup, is pointed toward the door and isn’t broken. If the antennae appear to be damaged, call your local repair professionals to inspect the problem and make repairs.

Lock Button Engaged: Another simple garage door fix is to make sure the lock button on your garage door’s wall mounted control panel hasn’t been engaged. You could accidentally press this button while performing normal daily activities, and you can easily disengage the door lock by pressing the lock button. After unlocking the door, test the door’s operations by pressing the panel’s open button.

Remote Needs Reprogramming: Before calling your local garage door repair technicians to inspect your malfunctioning system, you can also try reprogramming your garage door remote to the opener machine — sometimes, with regular use, the signal between your opener and remote can be disrupted and need re-association.

To reprogram your garage door remote, locate then press your opener’s learn button. Then, within 30 seconds, hold the button on your remote for three seconds or until garage door opener’s lights flash or the LED light on your opener blinks. Try using your remote to open or close your door to determine if the reprogramming was successful.

Door Control Wiring Malfunction: If the remote and wall-mounted panel method doesn’t raise or lower your door, then you may have a problem with your garage door system’s control wiring or the opener’s receiver board. Quickly test the quality of your opener’s wiring by following these steps:

  • Unplug the opener and disconnect the two wires from the motor
  • Reconnect your machine to power, then clear its memory and reprogram all remote controls
  • Unplug the device for a second time and reconnect the control wiring to the motor
  • Locate the wall mounted controls and disconnect the wiring
  • Use your garage door opener remote to test the functionality of your door

Do garage door openers have a reset button?

Newer garage openers usually contain a button that may be used to reset the system. If you have an earlier model, the garage opener is controlled by a dual in-line package (DIP). Radio frequencies and switches are used in DIP systems, however wireless signals are used in contemporary garage door openers.

How do I change the code on my Merlin garage door opener?

  • Check that it worked by pushing the garage door opener/closer button on the remote.
