I have a garage door opener that clicks, then hums, then clicks again when trying to operate.
I've taken the opener apart and isolated the noise to the control cricuit board. I've unplugged the opener several times for long periods to reset it, but nothing changes. this opener has been working fine for over 8 years so I think it may be a component faliure on the control board.

• 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 chain by adjusting the outer nut 4 to 5 turns. 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. • Decrease the UP travel by turning the UP Travel adjustment screw 2 full turns away from the arrow. • Re-tighten the outer nut so the chain is a 1/2" (13 mm) above the base of the rail. (When the door is reconnected and closed, the chain will sag. This is normal.) • If the trolley does not move away from the bolt, repeat the steps above. Also check the led light by the learn button. Does it flash in succession and then rest.....then resubmit question, also include model # If this is not the problem then your next step will be the logic board since the motor rarely ever fails. We also recommend a surge protector 900 joules or higher on all openers. Thanks BB
