What Causes the Liftmaster Wall Control to Blink Slowly?

Before we dive into the solutions, it’s essential to understand why your Liftmaster wall control is blinking slowly in the first place. The primary reason for this issue is a disruption in communication between the wall control and the garage door opener.
This disruption can be caused by a few different factors, including:

  • Dead Batteries: If the batteries in your wall control are dead or low, it may struggle to communicate with the garage door opener, resulting in a slow blinking light.
  • Electrical Interference: Sometimes, other electronic devices in your home can interfere with the communication between the wall control and the garage door opener, causing a slow blinking light.
  • Faulty Wiring: If the wiring between the wall control and the garage door opener is damaged or disconnected, it can cause communication issues and result in a slow blinking light.

Liftmaster Wall Control Blinking Slowly: How to Fix

Now that you know what can cause this issue let’s get into how to fix it.

Solution 1: Replace the Batteries

If the slow blinking light on your wall control is caused by dead or low batteries, the solution is simple: replace them! Follow the steps below to replace the batteries


  • Locate the battery compartment on the back of your wall control.
  • Use a small screwdriver to remove the cover of the battery compartment.
  • Remove the old batteries and dispose of them properly.
  • Insert new batteries into the battery compartment, making sure to match the polarity correctly.
  • Replace the battery compartment cover.
  • Test your wall control to see if the slow blinking light has been resolved.

Solution 2: Check for Electrical Interference

If you’ve replaced the batteries and the slow blinking light persists, the next step is to check for electrical interference. To do this, follow the steps below:

  • Turn off any electronic devices in your home that could be causing interference, such as TVs or radios.
  • When done, you should test the wall control to see if the slow blinking light has been resolved.
  • If the slow blinking light persists, try moving the wall control closer to the garage door opener. This can help to reduce the impact of any interference.
  • If moving the wall control closer to the garage door opener doesn’t work, you may need to install a garage door opener repeater to amplify the signal between the wall control and the garage door opener.

Solution 3: Check for Faulty Wiring

If neither of the above solutions works, there may be an issue with the wiring between the wall control and the garage door opener. Here’s how to check:

  • Turn off power to your garage door opener by unplugging it or turning off the circuit breaker.
  • Remove the wall control from the wall.
  • Check the wiring between the wall control and the garage door opener, making sure that all connections are secure and undamaged.
  • If you find any damaged or disconnected wires, repair or replace them as needed.
  • Reattach the wall control to the wall.
  • Turn power back on to your garage door opener.
  • Test the wall control to see if the slow blinking light has stopped.
