Securalift garage door opener wont lift the door

The motor works fine when it is not trying to lift the door but when it is it gets about an inch of the ground and then to act like it is jammed and can't lift it any further. The door will open manually no problem. It appears that when trying to operate the door like this it is skipping on the gears somehow because after trying a couple of times it affects the open and close limits. I tried to readjust these and also the force limits but this did not seem to help. Any ideas? Thanks Shane

SOURCE: garage door close but motor keeps running

The close setting limit switch needs adjusted. Once it is adjusted it should work just fine.

SOURCE: Sear 1/2 HP Garage door opener with replaced gears

The actual problem is after power on the opener, its initial state is uncertain. It may be in ready to close or ready to open state.

If the garage door is in closed position, likely the opener will still try to close it, because its initial state is uncertain. That's why you guys see it travels 2 seconds and reverse.

In order to fix this problem, after you power on the opener, do NOT hook up the chain, and do NOT mount the sprocket cap(so you can see the sprocket travel direction). While you watch carefully at the sprocket, press trigger button on remote control or ask someone press wall control button. Make sure the sprocket turns clockwise and stop. If the sprocket turns counterclockwise, press the control button again, so it will turn clockwise. Let it finish clockwise turn. At this moment, the opener is in ready to open state.

Cover sprocket cap and hook up chain. Mount door bracket and adjust. Your door must be in close position.

You are ready to go.

SOURCE: Craftsman Garage Door not working, motor seems fine

I have similar jerkiness problem and have gone through all the nine yards of possible causes. The motor stops at random position and at random time. Even when I unhook the door from the carriage, it still showed this symptom. It started when I had one torsion spring broken. I replaced both torsion springs and adjusted for weight balance. Make sure the two cables windup properly along the thread of the pulley; Checked the photo eye sensors; checked/test capacitor; cleaned rpm sensor; adjusted all possible force settings; make sure limit switch at sound; re-programmed my remote just to check if the logic board somehow still work on this side and it did;
One important observation I have is that when I adjusted the carriage chain, I've noticed that the opener unit turns off and on as if there's a loose connection/contact. This I pursued more. The more I investigate, I spotted a "tiny" spark on one logic board soldering at the transformer footing as I **** the back panel (where the board is mounted) back and forth to simulate the on/off due to the loose contact observed earlier. This one solves everything! All I had to do is take the logic board out and re-solder that failed connection and Hooray - it fixed the problem!
Hope this helps someone with similar issues,

SOURCE: Garage Door Goes down 5 inches and then up 5 inches.

Okay here we go.

Make sure you put the black cup back on the end of the motor shaft and that it is pressed all the way on. Make sure the RPM sensor is plugged in. If neither of these is the issue, then you probably did not have the motor shaft pushed all the way back when you tightened the coupler after replacing the worm gear. Loosen that coupler up and from the front of the motor (opposite end in which the coupler is on) push the shaft back as far as it will go. Hold it there while you tighten the coupler back up and then give it a try.

Garage door moves few inches and stops, springs are fine, sensros are fine.


If it is not blinking when it stops, then the capacitor is blown. Replace the capacitor and it should resolve the problem.

You have either a broken door spring or the drive gear in the motor unit is bad. The drive gear is a white nylon gear just in front of the motor and it will be obvious if it is bad.

My garage door wont open more than 6 inches with the door attached to the belt, but when I releasae the door load the belt works just fine. It worked fine for 6 months but now i have this problem....


YOU MAY HAVE A BROKEN SPRING

CHECK TO SEE HOW THE DOOR WORKS MANUALLY - DISCONNECTED FROM THE OPENER. IF YOU CAN'T LIFT IT EASILY THE SPRING MAY NEED TO BE ADJUSTED OR REPLACED.

IF IT LIFTS EASILY BY HAND THEN LUBE (WHITE LITHIUM OR WD-40) THE SPRINGS, HINGES AND OPENER RAIL - TRY IT AGAIN, IF IT STILL REVERSES ADJUST THE OPEN SENSITIVITY 1/8 TURN AT A TIME IF IT TAKES MORE THAN 3/4 OF THE ADJUSTMENT RANGE OR STILL DOESN'T WORK I WOULD HAVE IT LOOKED AT BY A PRO. SOME THINGS YOU CAN LOOK RIGHT AT AND NOT SEE.

HOPE THIS IS HELPFUL

Hi there. I have a Chamberlain Whisper Drive


I just had that problem this morning and the cause was that the springs that help hold the weight of the garage door were broken. This caused the garage door opener to raise the garage door a fe inches and then drop again. We called in a professional and $200 later we had new springs and everything works fine now.

Craftsman garage door does not open all the way stops @12 inches


You most likely have a broken door spring. Release the door from the opener and try lifting it by hand. Look above the door for the springs.
