We have a Craftsman 1/2hp opener. Back in October when the weather started getting cooler, the door would intermittently not close unless I held the wall-mounted button down. Now it won't close at all unless I do that each time. The door will barely move, then the light starts flashing as if there is an obstruction. It opens fine when using both the remote and the wall-mounted opener. I've lubricated all tracks and rollers. Any suggestions would be most appreciated!

Greetings Jaxbeach,
Check the lens on the door guard to see if they clean and are pointed right!
Good luck,
Jason
Your sensors probably think there's an obstruction. Also, check for a loose wire to/from the sensors at both the sensor and the opener unit.
If that's not the case, try opening and closing the door manually (with the opener disconnected). Do you detect a bind when closing?

Checking the sensors for a loose connection was a good idea, though it wasn't an obstruction problem. I have some wood stacked beside the receiving sensor and could not see that the green light wasn't on until I moved them out of the way. I disconnected it and plugged it into the other sensor's connection and it didn't work, so I now know it is a bad sensor. Thanks for the suggestions!
