My Lift Master (Chamberlin) does not work all the time. It will stop and return without activation. There is also a clicking noise, like a loud clock, when this happens.

1995 GMC SONOMA makes a loud sqeaking noise when i take off in the first to third gear, after third gear it stops, but when i get to a stop sighn it starts all back over, loud noise.


This type of noise is likely to be a universal joint that is worn out in the drive line. have a shop put it on a lift and inspect the joints.

Chamberlin garage door opens to top limit bounces back to return down about 6 inches and then returns to open limit. What adjustments are neccessary?


The limit switch of both the sides are not reached. The drive must be realigned to work till the door closes fully so as to touch the limit swittch to switch off.
Similarily the open door must go to the extreme point to cut off with the activation of the limit switch.

Chamberlain Lift Master Pro Formula 1 only makes click sound


Is the door stuck in the open position? If so the trolley is probably jammed against the bolt just in front of the motor unit. Loosen the chain enough to free the trolley and then run the opener until the door is closed. While the door is closed locate the 'up limit' on the side of the motor unit and turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

LOUD NOISE


Hard to tell without hearing it. But, if it is doing it all the time it is turned on but not in use most of the time that would be a fan making the noise. The other suspect would be a fault toner cartridge or the fuser. you may need to have a tech look at this.
Hope that helps...
