Why is one light orange on my LiftMaster?

 

A single orange light on your LiftMaster garage door opener can indicate a few different things, depending on whether it's solid or flashing:

Solid Orange Light:

• Battery Backup: If your LiftMaster has lost AC power and is running on battery backup, the light will typically be a solid orange. This is usually accompanied by a beeping sound every few seconds. Once power is restored, the light should turn green and the beeping should stop.

Flashing Orange Light:

• Low Battery: If the orange light is flashing, it usually means the battery backup is low and needs to be replaced. The beeping sound will typically be every 30 seconds in this case.

• Other Issues: In some cases, a flashing orange light can also indicate other issues with the opener, such as a problem with the safety sensors or the control board.

Here are some steps you can take to troubleshoot the orange light on your LiftMaster:

• Check the AC power: Make sure the outlet that the opener is plugged into is working properly.
• Test the battery: If the light is solid orange, try disconnecting the AC power and see if the opener works normally on battery power. If it doesn't, the battery likely needs to be replaced.
• Clean the safety sensors: The safety sensors are located near the bottom of the garage door track. Make sure they are clean and free of debris.
• Consult the manual: Your LiftMaster manual should have a troubleshooting section that can help you diagnose the problem and find a solution.

If you've tried these steps and the orange light is still on, it's best to contact a qualified technician to service your garage door opener.
