If it is not working at all and no lights are lit then check the power source. Try plugging a lamp or small radio into the outlet.

Try reprograming the opener to each remote, if this doesn't work then the command/radio module in the opener is damaged and needs to be replaced. Hopefully you can find one or you will have to replace the whole garage door opener. Good luck.

You can try programming the keypad using the procedure below.

To program the keypad, first unplug the garage door opener from the electrical outlet. Next, remove the nameplate from the console that the keypad plugs into and locate the program/operate switch. Flip the switch to program. Next, enter your desired four-digit PIN number into the keypad. Slide the switch back to operate and plug the garage door opener back in. The keypad should be programmed.

My Chamberlain garage door opener works fine except when the sun is shining, then it acts like something is blocking the sensor. How can I make the door opener work in the daytime?


There are a couple easy solutions for this. You can try switching the sensors side to side or use the cardboard tube that comes inside toilet tissue to shade the lens.
