Well finally had to call the service people in to fix the door opener , after six weeks of intermittent working and going up and down (on occasion) by itsefl , it finally would not work at all last Friday. Seems it was my fault /forums/images/graemlins/crazy.gif /forums/images/graemlins/blush.gif, once a year (in the fall) i lube with WD40 all the rollers and pivot points, + a few shots on the chain, seems the oil on the chain dripped off and got into the head and destroyed the RPM SENSOR. So he replaced the sensor and Reprogramed all the remotes and seems to be fine now. so a word of advice DON'T SPRAY THE CHAIN /forums/images/graemlins/grin.gif
