It has the "Protector System" (safety sensors). chec the sensor indicator light on the receivinng eye the green light had a slight flicker.cleaned both the sending eye and receiving eye lens of dust and cob webs, then realigned the receiving sensor for a steady green indicator light. then check the door function it now works fine.over time, temperature, and viberation the sensors become dirty and get out of alignment, as no one had tampered with the sensor alignment prior to this. Hope this works for you.

Will the remotes work in the garage? If yes but not outside with the door closed you might have radio interferace with your remotes. You might have to chage to a your reciever and remotes to a different brand (frequency). Sometimes it is less trouble to change out the operator. Chamerlain changed frequency from 390 (old) to 315 (new).

2 flashes is a safety eye issue, but you problen is most likely that the chain is not sync with the limit setting. Take the bottom off the gear and sprocket assemble and rotate center limit srew until it is in the same position as the trolley.

If you can not open the door sounds like you might have a broken spring. Call a professional do not try to repair the spring yourself.

Sounds like it might be a resistance (weight) issue. It's not the temperature since mine opens when my garage temperature is 15-20 degrees (outside temp even lower).
