More than likely you have broken the item designed to protect the machine. Look for a hole in the hub of the sprocket as it was probably a shear pin try turning over the shaft until you can see the hole to knock out the broken bit. It may also be a key in the key way.

My l/m door goes down but come right back up help


This can be one of two problems ! First problem can be that their is something blocking the infrared sensors that would cause the door to go back to the up position but in most cases if their is something blocking one of the sensors the door should not even move and just make a click sound and you will see the lights flashing on the garage door opener , it can also be a mis aligned sensor not pointing directly at the recieving sensor or vice versa! Ok if that was,nt the issue then you can make shure that the door isn,t traveling further then where it needs to stop to be closed, sometimes the chain or belt depending on your opener loosens up and can add an extra inch of travel to the door causing it to return to the up position, to fix this you have 2 adjustments on your opener ...1 will be a pressure adjustment ...you can turn the adjustment to midway #6 to add some pressure so that the opener does not sense the xtra travel of the door , You can also backoff on the downtravel adjustment a turn or two and that will make the door not come down as far ...This adjustment is used to set how far the door goes up and how far you want the door to come down, you will see a picture of the door on both of these adjustments with an arrow letting you know which way to turn the screw ..remember each full turn of the screw equals 1/4" inch of travel to the door just follow the direction of the arrow or turn the screw counter clockwise for less travel !,,,Hope this helps you Sincerely Glenn

The garage door will open and then close then open and then the light starts to flash it's a Merlin 230t


This just happened to me. The issue was that the chain that the motor moves back and forth to open/close the door needed to be tightened as the tension had become slack, so the door was hitting the ground hard when it closed and the system automatically raised the door. I closed the door by adjusting the downward travel and then tightened the chain tension by twisting the bit at the of the chain (you'll see it and can use your fingers to do this), once done, then it was a matter of adjusting the upward and downward travel knobs and testing the door to make sure the door was back to normal.

Door closes all the way but then opens again


you can try adjusting the down force. what it sounds like when the hits the bottom the force sensor is saying there is an obstruction and is opening back up . just turn the down force adjustment higher on the logic board. if this isn't the problem you may have to adjust the down travel control, it maybe trying to force the door down to far and causing the force sensor to open door back up. if it is trying to force door to far in travel when the door goes down when it hit bottom you will notice the chain sag or the t bar will bend. good luck.

MY GARAGE DOOR KEEPS OPENING AND CLOSING. AND ONE OF MY SENSORS IS ORANGE INSTEAD OF GREEN. WHAT IS THE PROBLEM?


As I have mentioned in other post, re-program travel and force limits. Make sure that travel limit (down) does not go too far (thus excessive force). Apparently this system has a force sensor that senses if there is something in the way of the door. This is different from the safety sensor "eyes". The problem in your setup is that you have programmed the door to travel down too much and he system looses its ability to use force sensor. Adjust travel limit (down) to a little less travel and you will be fine.

Chamberlain 4200C doesnt open or close properly


You did not sync the chain correctly. If you have not touched the travel limits, take chain off sprocket and run door to either up or down position. Put chain back on with trolley in up or down, accordingly. Tension and make final travel adjustments.

Adjusting front derailer


Typically adjusting the front derailleur is a matter of adjusting the two adjusting screws on the derailleur. So turn the bike upside down. It should sit on its seat and handle bars. Find the two adjusting screws one will prevent the derailleur from traveling too far out preventing the chain from coming off. The other screw prevents the derailleur from traveling too far in keeping the chain from falling off that way. Now once you have found the screws slowly start turning the pedals like it was being ridden. Move the derailleur out as far as it will go if you see the chain is about to come off adjust the screw. Do same for inside screw. Now move the back derailleur all the way in and retest front derailleur, repeater with rear derailleur all the was out. Hope that helps. Oh, the back derailleur adjusts same way.
