Whenever I have a service call that the customers are claiming they hear the motor but don't see the chain moving 9 times out of 10 it will be a stripped gear ! if this is the case call a professional to replace it , the cost should be around $100 to replace , if that's not the case look for a jammed carriage or trolley , this is the part that has the swing arm connected to it that is attached to the door and the trolley , Sometimes a machines adjustment can override it's travel limit simply by a loosening chain and travel beyond it,s original setting on the up travel only (never when the door comes down) When the door is going up and has added a few more inches of travel there usually is a stop bolt that is in place before the light cover of the machine , this bolt is there to protect the plastic light cover but I never install them because customers don't normally do maintenance on their garage door openers and tighten chains and adjust travel limits ,,,They call me ! if you do have a jammed carriage or trolley this bolt must be removed but since it is under pressure you must loosen the chain before doing so to take the pressure off , After you have loosened the chain you will need to unscrew the nut on the stop bolt which is a 1/2 inch standard socket,,,after the nut is removed you can whack out the bolt and the carriage will now be free from the jam , after tightening up the chain again remember to check the travel limit that got you jammed in the first place and back off a few inches in it,s setting ! Good luck and if I was any help to you please leave me a nice review , Thank you Glenn

IF THE MOTOR IS JAMMED (JUST HUMS) LOOSEN THE CHAIN AND ADJUST THE LIMITS AND TIGHTEN CHAIN.

IF THE MOTOR ACTUALLY RUNS AND THE CHAIN DOES NOT MOVE THE DRIVE GEARS NEED TO BE REPLACED. THEY SELL A KIT THAT INCLUDES THE BUSHINGS AND SHAFT. DO NOT BUY THE SMALLER KIT AND DO NOT REPLACE ONLY ONE GEAR (THE OLDER WORN GEAR WILL CHEW UP THE NEW GEAR) THIS MAY BE WHAT YOU HAD DONE - IF SO CALL THE SERVICE GUY THAT DID THE POOR REPAIR AND HE SHOULD REPLACE BOTH GEARS UNDER HIS SERVICE WARRANTY. ANYONE WORKING ON THESE SHOULD KNOW BETTER.

GOOD LUCK.

Why rear windows on 2001 chevy tracker won't work ?


Would seem your into the inner doors & have a partial
grasp on things

Now you fix all door windows one shot

#1 Test all switches,ohm meter unplugged or volt meter with power
#2 Test all motors with battery voltage direct -- DC motor will run either direction-- can't hook up wrong
#3 Window Regulators -you know about them (Unless they are broken-you said they are tight)
#4 Do you have good ground side wiring & battery voltage at all
switches & motors
#5 Last resort--unhook the cables & work on freeing up the
glass & window guides etc then you will have found out if the
regulators are the issue

All garage door openers have a quick release. Have you checked to make sure that is locked in place? Most have a cord hangin from it and you pull it which releases it from the chain. Make sure that is engaged and it should work.

Motor runs well but chain wont move,l it only 3 months old what next?


Make sure that you can move the chain by hand and that it is being properly oiled. Remove the bar and chain after releasing the chain brake. Clean the side of the engine where the bar fits to, then start the engine--oil should ooze out of the port. Wash out the interior of the clutch with spray carburetor cleaner to clean away excess oil accumulation. Clean the drive end of the bar small oil passages that run from the large holes out to the chain groove on each edge. If oil oozed out during the run test, reassemble everything making sure the chain teeth cut toward you on the bottom run. Adjust the chain up to the bar, but not so tight that you can't move the chain by hand. Tighten the cover fasteners and recheck the chain tension. Start the engine and run the bar tip near some cardboard--it should throw off a thin line of oil after several moments. Hope this helps!

Motor runs but chain does not move?


Check the chain drive sprocket to see if it moves when the motor runs. If not, there may be a sheared key between the shaft and sprocket or the teeth on the sprocket are badly worn off. Hope this helps!
