It didn't work, so I put a new battery in the remote. Worked for several days, but then not today. Motor of opener did not engage (not a problem w/rollers etc.) I already checked the sensors and power source etc.
the most common issue with a garage door that just suddenly stops working is the motor capacitor. Its an easy and cheap replacement part. a usual symptom if a capacitor going bad, is a garage door that starts to get slower to open. sometimes this gradual slowing happens at such a slow rate that most people don't start to notice until it finally stops working. The best place to find a capacitor for you particular opener is inline or at your local Garage door repair shop. I can bet the repair shop will charge you FULL RETAIL price. I can't promise you that's whats going on with your particular situation, but I can say that most our issues with a sudden stop of an opener has been the capacitor. I hope this helps. Good luck to you
