I know that it can be very frustrating to have issues with the garage door opener. When the indicator light flashes it is communicating an error in the opener. Five flashes means that the RPM sensors has most likely stop communicating. I'm sending information for this code. Also check the following.First verify that the trolley is against the stop bolt.Release the door from the opener by pulling the Emergency Release Rope.Manually bring the door to a closed position.Loosen the belt by adjusting the outer nut 4 to 5turns.

This relieves the tension.Run the motor unit from the remote control or door control. The trolley should travel towards the door and stop. If the trolley re-engages with the door, pull the Emergency Release Rope to disengage.Re-Tighten the outer nut until the trolley spring is approximately 1-1/4' (3.18 cm) in length. If the trolley does not move away from the bolt, repeat the steps above.Also make sure the safety sensors are correctly installed and aligned.If you need further assistance, please reply to this thread.

However, this is one of the most expensive parts on the opener. They can range from $80 to $100 depending on the model. Most of the time it is more cost effective to replace the whole unit.

I completely cleaned and re-lubricated all rollers and the rail, still broke. Read about 'replace the circuit board', so I'm thinking 'Maybe the circuit board is dirty?'

Removed both circuit boards, cleaned them with static-free cleaner, replaced them. THEN I THOUGHT OF THIS: MAYBE THE POTENTIOMETERS FOR THE LIMIT SWITCHES ARE DIRTY! Just how the volume control on your old radio gets dirty and causes crackling of the sound, these 'pots' can get dirty in your garage, too. All I did was rotate the limit pots all the way left then all the way right about ten times each. I reassembled the opener, and PROBLEM IS FIXED!! No parts replaced, just cleaning it.
