Chamberlain Garage Door Opener Start Stop Switch - Defective Unit Shown

I was having trouble with my garage door opener closing all the way just to reopen. I called the tech support at Chamerlain and the guy told me to pull the cover off and see if I could see if the adjustment screws were working fine. they were. It was the switching unit that was bad. As you can see in the video, the motor did not shut off after making contacts. So I replaced the unit and it worked fine. Just wanted to show this incase it can help someone else out.

@yoshifan125 Yeah, it sure is. Once I got the problem fixed, its been a great door opener.

[daniel981]

Yep - Thats the one! ;) Being that you are well experienced with them, is that a good one?

You're going to need to replace the limit switch assembly, there around $15-20 on any online garage door dealer.

It was a brand new unit, so I just ended up swapping the whole motor assembly. problem solved.. I just posted the video so someone would see what it should not be doing. Thanks for the comment.
