Last fall, I had problems closing my garage door and discovered that the sun was hitting the 'eye receptor' causing a false reading. I switched the sensors and the problem cleared up...until this spring. Same problem. In the short term, I'm switching the sensors, but does anyone know of a more permanent solution? I've thought of moving them back inside the garage, but that solution limits my already limited storage space. Thanks for your help.

Thanks Jack for your input... but wanted to give an update so if theres anyone else that comes across this same situation they will have some ideal what to ck. My husband and I were able to fix the 9 yr old garage door opener and it works like new. If your at all handy and have this problem where the door seems to just slide down the screw drive when it closes it is most likely the CARRIAGE has worn down the metal teeth inside it. Just take the track apart close to the carriage (not hard just a couple of bolts) and slide the carriage out..you will be able to see if the teeth are worn down..after calling a couple of pro installers for the part and them telling me that on a screw type opener that the carriage is usually the first thing to go and for 10 bucks and 10 minutes to install the part the opener works great! Even if we only get another yr out of it..it was worth it. Also the pro said that our opener has most likely lasted for 9 yrs because my husband has always greased the track every yr. So guess that was one of the most important parts of the instructions...hope this helps someone else out there..Have a good day!
