Question:
My garage door makes a beeping sound every couple of seconds. What should I do?
– Richard L
Answer:
The garage door beeping function is a built-in alarm system commonly found in LiftMaster and Chamberlain DC models with a battery backup feature. It typically activates for the following reasons:
- Loss of Power: If your garage door opener is not receiving power due to a power outage or a non-functional outlet, the system will beep. Additionally, the garage door may operate more slowly than usual when powered by the backup battery.
- Backup Battery Failure: The beeping sound can also indicate that the backup battery is no longer functional and needs to be replaced. This typically occurs 1 to 3 years after the battery’s initial installation.
How to Fix Your Beeping Garage Door
If your garage door opener is beeping, follow these steps to resolve the issue:
1. Verify the Source of the Beeping
Before taking any action, confirm that the beeping is coming from the garage door opener and not from other devices in the garage, such as smoke detectors, battery chargers, or similar equipment.
2. Check for Power
Ensure that your garage door opener is receiving power. Test the outlet by plugging in a device, such as a phone charger, to confirm it’s working.
3. Address the Beeping Alarm
If the outlet is functioning, there are two ways to stop the continuous beeping of your garage door opener:
- Replace the Backup Battery: For instructions on how to replace it, click here.
- Remove the Backup Battery: Disconnect and remove the battery. Note that without a backup battery, the automatic garage door opener will not operate during a power outage.
If the issue persists after following these steps, consult a licensed garage door repair company or a certified dealer for assistance.
