Craftsman Garage Opener Clicks only and LED blinking 5 times
My 1/2 HP Model 139.53641SRT opener clicks to all my remotes open button (I have no wall mount) but the motor does not move.Â The LED next to the green "Learn" button blinks 5 times and pauses for 2 seconds continuously after I hit the open/close button on my 3 button remote model 139.53779 (LED does not blink right after I re-plug in AC power).Â http://ths.gardenweb.com/forums/load/garages/msg012015459574.html indicates a 5 blinks is a diagnostic for ""RPM sensor or motor overload".
I verified obstruction sensor works and aligned.Â I also opened the opener housing and verified the motor gear to be fine.Â Is there anyway to checkout the motor and the RPM sensor?
(Right before the opener stops working, I open the garage door and accidentally hit a button on the 3 button remote that I normally don't use to close it about 5 minutes later and the opener started to act that way.Â I tried holding the same button for 2 seconds just in case that is the "locked" button for vacation and the opener still behaves the same. I wanted to make sure that I did not accidentally lock up the opener by hitting a wrong button on my remote and end up replacing the opener if someone out there can tell me how to unlock it.Â I have no owner manual because the opener and remotes came with the house.)
Thanks for your help.
