20 Most Recent Chamberlain 1/2-HP Whisper Drive Belt Drive Garage Access System Questions & Answers

Hello Pat Remus,

Chamberlain... Has been around for a very long time
... type of door... presumed to be OVER-HEAD...
Operation issues .... (were okay (?) sudden fialure

EASY to check...
CAUTION: doors can be EXTREMELY heavy.

FROM the closed position... (to avoid a door crash)...
You should be able to disconnect your GARAGE
opener... and feel the well balanced motion rom the
full open to FULL closed.

If you hear any chatter of springs.
THEY need to be lubed (often)...


That "chatter"
will turn into "SHATTER"...
Those springs will break... and need to be replaced
( pretty RISKY job best done by a SERVICE company )...

If the door is quiet & well balanced...
Then it is time to check the "travel" contacts...
and adjust them the the proper HEIGHT is achieved.

>> READ THE MANUAL... OWNERS (model??)
No exact matches found Try these results

Hope this helps...

Do you have a security system in your home? Sometimes the door shut sensors get out of alignment and the door strikes the sensor. This is the exact same problem I had with my door.

You may need to replace the battery in the remote control. Most usually these will be double A ones. You may have to reprogram it when you try it again. You should be able to get the information on Google by typing in the make of the inside unit in your garage. Your remote may have this info on it as well. You should be able to pull up instruction on how to reprogram your unit.

could be that the remote operation or cycle operation needs reprogramming as it indicates that the program has a corruption in it and the action is lost by that corruption
follow the user manual and do the reprogram sequence

I just installed this opener 1 week ago and the same thing happened. I remembered there is a "Belt Cap Retainer" that covers the motor sprocket and is held on with 2 screws. I removed the cover and the squeaking stopped. There is a small dab of grease (silicone?) that the instructions did not mention. I spread the grease around the cover next to were the belt travels and put the cover back on careful not to over tighten the screws. No more squeak!

Seems like you either have your photo cells out of alignment or disconnect from operator or a short in the photo cells wires.... make sure the you can see the green LED light on one and a amber/red on the other at the same time with no flashing or flickering. The green represents power supply to units and other color represents alignment, both are a must! so make sure you see them on solid without blinking or flickering.

I'm not familiar with the whisper drive but I would start with the most obvious place for a problem. There are two units at teach side at the bottom of the door jam. They have to be lined up for the door to work. This is the most frequent problem I have found because they are close to the floor and can be bumped out of alignment. Check to see if one of them have been moved. Most of these little plastic units have a plastic locator pin in the top of the unit. these pins snap into the mounting bracket. If the unit has been bumped just move the pin until it snaps back into the bracket. I'm not a contractor but I have seen this happen a lot with friends and family. Ask the easy questions first. Is it plugged in? Is the breaker in the power panel tripped? Good luck

There's a lot of things that can cause range issues. Wireless routers to close to the garage. Bad LED or CFL bulbs. Faulty circuit board. A faulty motion detector on a light. Sometimes if you turn all of the breakers off except to the garage you can isolate it. If that doesn't help call a garage door company to come out.

Yes but certain brands have been reported to cause range issues with the remotes.. If you contact Chamberlain that have a list of the brands and wattage to use.

Make sure the dip switches on the transmitter match those of the receiver
