Allister ARD II will not open.
(Sarasota, FL. USA)
My ARD II will not open. (It closes fine).
It makes a buzzing noise that is coming from a relay looking box on the circuit board. I manually rotated the motor to position the opener to simulate the door being half open. Press the button it will move to close, press again it stops, press again I get the buzz. The closing circuit works-the open does not.
Any suggestions to determine the bad component? I did see a post elsewhere that suggested the capacitor could be bad??? I hate to buy one without more insight into the problem.
THANKS for your help...
