my Sears craftsman 1/2 hp (model number 139.18874) garage door closes and opens fine with a remote. However, when i close the door via remote or the wall panel, the door goes down, hits the floor for a few seconds, and then comes back up.
Here is a video that may explain better: https://youtu.be/F5DQLjm5dxA
I’ve gone through the forums and have checked the following:
[list="margin-right: 0px; margin-bottom: 20px; margin-left: 15.4688px; padding-right: 0px; padding-left: 0px; box-sizing: border-box; -webkit-font-smoothing: antialiased; line-height: 1.42857; color: rgb(85, 85, 85); font-family: Lato, Arial, sans-serif; font-size: 10px;"]
[*]checked the 2 censors to make sure they are aligned and the green light is on,.
[*]I’ve cleaned everything around the sensors it to make sure there is no obstruction.
[*]I have also unplugged and plugged in the power to the motor
[*]I’ve played around with the up and down tension adjustments in the back
[*]I’ve tried holding the wall button to by-pass the sensor. The door still doesn’t stay down. Which makes me wonder if the issue is with the motor unit?
[/list]
I called a couple of repair guys and they both quoted me $150 to come check it out. I am hoping someone here can help from having this unexpected expense.
