This can happen when power is interrupted. Try this. Unplug, let it sit for a minute and plug it back in.

There are screws on the unit to adjust the opening and closing tension and place it stops. They are probably set for the previous installation and need to be adjusted for yours.

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.

Call Chamberlain and ask if the handheld opener is compatible with older syster

There should be a battery on your wall unit that needs replacement. God bless your efforts.

no, chamberlain openers require chamberlain, liftmaster, or craftsman safety eyes

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.

Chamberlain... | Answered on Sep 16, 2017

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
