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

1 Answer

Remote My Chamberlain remote works sporadically. We have both the remote that came with the system and a built-in remote in one of our cars. At times it will open from the street in front of the house; other times you have to be almost touching the door with the car; and other times it doesn't work at all. Not a battery issue because the it happens in the car with the built-in system too. The antenna is not obstructed on the unit.

    Just after a recent thunderstorm I found my garage door up. Now I can get it to work only sporadically from the touchpad or the remotes. HELP!

    I have the same problem. I also have both remotes..both cars with built in remotes and sometimes I also have to almost touch the garage door with the car to open it. Other times it doesn't work at all. Even the remote keypad gives me problems. Sometimes I just press the open button repeatedly as I drive up to the garage and I get lucky and the door opens. Those times I feel like buying a lottery ticket because of how lucky I was to open the door. Is it possible that there are interfering frequency signals from other devices causing this. I have Brinks wireless components and 5.8Ghz cordless phones.

If it happens to both remotes and the built in system the problem has to be with the reciever in the unit or antenna, where you have this unit is it inside a metal building? if so you may need to move the antenna outside the building.
good luck

Check or change your batteries. Age and weather can effect a frequency change in the transmitters performance. Are the car remotes still functioning at their original distance? If there OK then the receiver in the garage is still "tuned in". I am assuming your describing a "remote" wall control unit.

Regards the remotes. One of them has reverted to an earlier technology and they will both work but not together. You will need to purchase a new remote (make sure it is the same model). Once you have the new remote you will need to program them. One of your old remotes will work with the new remote and the other will not. Remove the batteries from the bad one and trash it. You will have future problems if you don't.

For your car opener. If it is Homelink you can call this number and I am sure they will help you. You will need to be in your car and at your garage. 1-800-355-3515

Remote does not open garage door

It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.

didnt try everything cause if you did, it would work! Get two people and garage door opener. One read manual from car under Garage door" or Homelink while other pushes button. When manual says if this did not work or if you have security plus or rolling code, continue with other instructions. You will need a working remote and will need to pushh learn button on motor logic board.
