Question about Chamberlain Powerdrive PD422D 1/2 HP Security Plus Screw Drive Garage Door Opener

Red LED light remains on and beep sound

Chamberlain Whisper Drive Model 248754 is less than two years old.
The red LED stays on and a beep sounds every 30 seconds or so.
The manual only says "contact for service".
Any suggestions/advice so that we can fix ourselves or at least know what's happening before calling for service?
Thanks!

My battery is bad. I knew it, but did not feel like it was worth any of my attention. The beeping started yesterday and this was worth my attention. Everyone in the family complained. I suspected it was the battery.

I unplugged the unit. Disconnected the battery. Waited for 30 seconds. Plugged it back in. It works fine and no beeping.

I suspect it is a warning to replace the battery.

There is a beebing sound coming from the unit every 60 seconds. What can I do?


This sounds like the unit may be running on its battery and the battery is running low. Is the orange light also blinking? (The LED is on the side near the worklight so it's easiest to check if the light is off.) First check if the power is on to the house and then to the garage area. Next check if the garage door opener is plugged into the outlet. Make sure that the battery is properly connected to the wiring harness (and the opposite side of the harness is fully seated as well).

If the LED is red and the unit is beeping, then replace the battery for the opener. The battery kit is part 41A6357-1 for the WD962KD Chamberlain Evercharge model. The Chamberlain 4228 is a substitute battery kit and is available at Amazon and other vendors. It is a little harder to put in the opener (and then remove later).

If a new battery doesn't solve the problem (after 48 hours of charging), then the opener's recharging circuitry has failed and can't recharge any battery. Depending on the age of the opener, you may be better off replacing the entire unit.

The manual for the WD962KD opener is available from Chamberlain here: http://www.chamberlain.com/doityourself/pdfdocs/114A4249.pdf .

Please add a comment with your garage door opener model or check your manual to get the correct battery for your opener.

I hope this helps.

I ahve a beeping sound that is coming from my garage door opener.


If you have an opener with battery backup this may help. BBU stands for 'battery back up.'

This is battery related. On top of your unit is a battery pack with three colored led lights. You can tell what is going on by looking at these. This information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing GREEN LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.

I have a Chamberlain Whisper Drive and it started beeping. Reading the manual, it seemed that I needed to replace the battery. It is about 5 years old. Replaced the battery and the LED is no longer red but...


On the back of the garage door opener there is a red button. Depress this button and sync your keypad to the opener. This will re-establish the code and reset the remote.

Chamberlain silent 3/4 hp red led on side and hear beeping sound garage door opens and closes, but the beeping sound is annoying? what is causing it


This beeping is actually the battery back up unit making this sound. It either means there is no power to the outlet and it is using stand by power or that something is wrong and the battery is not charging correctly or will not take a charge. You can order replacement parts at chamberlain.com. Thanks BB
