Craftsmangarage door opener problem

misfitMay 10, 2009

Model # 139.53638SRT

When I hit the remote control the door moves about a foot. It then stops and comes back.

It sometimes stops between limit switches. If I push the remote a few times it will come back to the limit switch and then work fine. Maybe a couple of hours later I can push the remote again & it is screwed up again.

I have checked the sensors and they are working fine.

I adjusted down force control, sometimes it helps and other times it does not.

The garage door moves freely when not attached to the opener.

Any suggestions?

TIA

It sounds like you may have a problem with the RPM sensor which is a small printed circuit board just in front of the motor. Check the small LED just to the left of all those white wires. It may be giving you a code. 5 flashes and a pause repeated over and over is the code for RPM sensor.
