if he just turned the cams over by hand then i doubt that he damaged anything as if a valve was open when the piston came to top dead center then it would have stopped moving.the noise isn`t uncommon because the valves springs will make some noise as they are compressed and the rockers will make some noise as they move against the cam lobe and and the valves will make some noise as the valve spring forces the valve shut.if when you aligned the cam marks and they didn`t hit the pistons and stopped you from moving the cams and all timing marks are aligned then you should be okay to start the motor.

Chamberlain chain gdo. goes all the way up until it hits gdo box and gets stuck. unstick it and it works for awhile then it happens again


Unstick it and close the door. While the door is closed locate the 'up limit' control on the side of the motor unit. Turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Should be good to go.

Chamberlain GDO light turns on randomly at any time of day or night. (Whisper Drive with Motion-Detecting Control Panel 935CB.)


If you don't have any puppies or strange animals running around your garage I would disconnect the wall control for a couple days. If your problem stops I would suspect that control. If you have a heated garage I would also make sure there is nothing that could be moving from the air movement from the furnace.

If your door is stuck in the open position the trolley is most likely jammed against the bolt just in front of the motor unit. You should be able to loosen the chain enough that it releases the pressure on the trolley and then close the door. While the door is closed, locate the 'up limit' control which is on the side of the motor unit. Turn this control 2 full turns in the opposite direction of the arrow printed on the cover and then tighten the chain.

Loosen the chain enough that you can remove it from the pulley on top of the motor unit. Now with the door closed run the motor until the pulley turns in the clockwise direction and stops. Put the chain back on the pulley and tighten. You may have to tweak the up and down limits now.

Sears Craftsman Gar. door opener won't respond


There isn't a fuse. You are going to need to remove the cover on the opener and find out where you are losing the power. Maybe a neighbor has a volt meter you could use. I would check the power cord and then the logic board. Makes no sense but I would check for burnt or missing traces on the printed circuit board especially around that small transformer.

Liftmaster gdo won't operate with door or remote


Hi there, when the problem first started was the door being used frequently? If your GDO was used quite a few time's in a short period of time the "overload" may have triped. The makers of all GDO's now adays install an overload witch is an electrical safety device protecting the motor. This prevents over heating in turn burning up the motor. To rectify unplug for 15-20 mins. If you have Model number 1270 turn to pg. 7 in owners manuel. Insure all door locks are free. Insure power to electrical outlets by pluging desk lamp in same out as GDO. what model do you have?

Receiver frying noise


I have the same unit and discovered there's 2 cooling fans inside.
one is not working at all and the other is turning very slow.
With that said I'd open the cover and see if it's the fans.
