There is a button on the side of the wall-mounted remote. It has a pic of light bulb next to it. Press it once - the motion sensor is on and the lights will be on once it senses the motion; press it again and the motion sensor will be off.

Battery is bad. I removed it and garage door opener is still beeping. It is driving me crazy. Help

as long as garage door is powered(plugged into outlet), then with a removed battery backup or a bad backup battery, the unit will beep to alert you to the issue. replace the backup battery with a new/good one.

I recently bought a Chamberlain 3/4 hp belt drive MyQ garage door opener. I had an old garage door that I thought was bad, I'm not sure now. The old door opener would lift the door about a 1ft to a 1 1/2ft...

How is the door balanced currently? In manual setting (without the opener) can it be raised by hand, will it hold at it's halfway point, and will it hold at fully open?

These all have to be be in balance before adding the opener.

I just replaced my rollers (Ideal Security SK7123 1 7/8-in Deluxe Nylon Rollers Commercial Grade 11 Ball Bearings) and they made a world of difference to quietness and opening. Plus, more importantly, they gave me clues as to the RHS being misaligned.

There are several videos out there dealing with door side to side imbalances also.

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: .

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.

You will need to research your particular model--there's probably a model number listed on the opener.
