Questions and answers
Gear broke off fixed it now door closes to far and goes backup to far gets jammed
If a Chamberlain 1260 - 1/2HP garage door closes too far and gets jammed after fixing a broken gear, possible causes include:
1. Travel limits not properly adjusted—travel limits may need to be decreased to prevent the door from closing too far.
2. Force adjustment set too high—excessive force may override the safety reverse system and cause jamming.
3. Binding or unbalanced door—if the door is not properly balanced, it can cause issues during closing.
4. Installation errors—such as incorrect positioning of the header bracket.
Travel limits and force settings should not be used to compensate for mechanical problems with the door.
