Tools and Hardware Reviews of Chamberlain PD432D 1/2-Horsepower Screw Drive Garage Door Opener

Customer Review: Smooth and quiet
Summary: 5 Stars

I bought this unit to replace a 10yr old chain drive who's sprocket axle snapped.

The new unit is about the same speed as the old chain drive, but much quieter. It's installed on a double wide door w/ central located torsion spring (i.e. twisty spring not pull spring.)

It doesn't work with pre-2005 rolling code remotes which is a bummer as I'm still using my 10yr old chain drive on the single bay door, so now I've got two remotes to deal with. I had no problem programming it for the wife's '09 Impala are a new exterior security remote I added.

Install was a breeze since there was an existing garage door opener that was installed well and the mounting brackets on the door and header above the door where identical I simply reused them as well as the safety sensors. I tossed the new ones in my junk pile just in case one fails at some point in the future.

The only thing that was a bit negative on was the force sensitivity adjustment screws for how much force is applied at max when opening/closing the door before reversing direction when it binds or something is blocking it. I'm guessing they used cheap POTS for this. I made a turn of less than 5 degrees and it goes from not sensitive enough (would crush a box)to being to sensitive where the slights pressure causes it to reverse and about 50% of the time the door wouldn't close before reversing from the pressure of typical shifting.

That being said, I did a few more tests as I had read about how some people claimed it wouldn't open there doors. I stood on the inside lip of the door (275lbs in addition to the door itself) and turn the sensitivity adjust up - not all the way and it lifted me 18" before I stepped off. Now this is a steel garage door, that in and of itself weights 240lbs, add me that's > 500lbs. Panel wood doors are in the 350-400lb range.

If this garage door opener is having problems opening you're door, you need to either adjust the lifting force sensitivity screw up or adjust/replace your springs. If you have torsion springs (mounted on the wall above the door) then take some graphite or Teflon spray lube and spray it along the spring (try aiming more for the top) and it will reduce the friction of the touching surfaces as the spring is twisting and untwisting.

One final piece of advice. If you're replacing the side springs - use a guide/retention cable down the center of the spring and attach it at each end. We had one of these springs break when I was a kid back in the 70's and it was stuck in the back wall from the force. A cable would have kept it from flying around the garage and may save someones life.
