My LiftMaster garage door opener was working fine, so why is it suddenly beeping? Is this normal, or should I call a technician? A garage door opener may start beeping for various reasons. Some are simple to troubleshoot with a basic understanding of its components.
However, some issues may require professional assistance to resolve. Some garage door opener beeping sounds may indicate a need to replace parts. However, this is really only common in older units that have already exhausted their lifespan.
If you are looking for replacement parts, visit All Security Equipment and browse our product lists. We provide authentic garage door replacement parts, such as sensors and batteries, to fix problems with beeping door openers without having to replace the entire unit.
Why Does My LiftMaster Beep?
Garage door openers communicate through blinking lights and beeping sounds. The number of beeps is the indicator of what the unit is trying to process.
Here’s what those beeps typically mean:
Normal Beeps
- Once: The garage door is opened/closed, or the timer-to-close has ended and the door is closing
- Twice: Connecting to the server
- Slow beeping three times: Connecting to a network
- Fast beeping three times: WiFi has been erased from the garage door opener
- Beeping six times: The garage door opener failed to connect to the server
Constant Beeping
A constant garage door opener beeping sound is likely due to a battery problem or system errors. These auditory signals are accompanied by visual indicators or blinking garage door opener lights.
Battery Backup
If your LiftMaster garage door opener starts beeping after a power outage, it usually means it is using its battery backup. This will cause the opener to beep every two seconds, and the LED light becomes solid orange.
Low Battery
After using its battery backup for a while, it will begin running low. This will cause your LiftMaster garage door opener to beep every 30 seconds, and the solid orange LED will start flashing.
Dead Battery
If a solid red light accompanies the beeping instead of a flashing orange, it could mean that the battery is dead. Reconnect it to a power supply to recharge. If, after recharging, the solid light and beeping do not go away, your battery may need to be replaced.
Needing a Reset
If the LiftMaster garage door opener keeps beeping even after addressing the battery problem, it probably needs to be reprogrammed.
If necessary, follow these steps to reset your LiftMaster garage door opener. Resetting the unit erases the motor memory, so you may need to reprogram your remote control and keypad connection.
