I installed my second door opener today and it hasn’t gone well. The first was flawless and works awesome. The second is have the following problem.
When closing, the last section of the door appears “bind” and put a huge amount of pressure on the trolley system/travel rail. It puts enough pressure that without the down pressure maxed out, it won’t close and starts heading back up.
Here are the steps I’ve tried to troubleshoot this:
Verified centered on door.
Door does not stick when trolley system is dis-engaged.
Measured trolley mount location is within 1/8th of an inch of working system.
Decreased down travel setting and increased door to trolley connection rod length.
Now once i’ve got the door closed, there appears to still be a large amount of tension/pressure on the trolley travel rail. So much it’s arched. Working door does not have this problem. Lastly, when I disengage the trolley manually and run the door up and down, doesn’t seem to bind, so I don’t think the door is out of whack.
So, any experts out there who can help the mechanically challenged.
