I pressed the wall button and the door opened. When I went to press it again to close, it did nothing. The door remained opened and I had to manually close it. There are no noises from the opener.
The button I am referring to is the wall button as there is no remote.
The trolley is NOT stuck on the bolt. I had to pull the emergency release handle to close the door. Lights work and the "learn" button indicator lights up which is the only way I can determine there is power reaching the opener.
Holding the wall button makes the green indicator light flash.
Is there a numeric pattern to the blinking light near the LEARN buttton?
No pattern. Solid orange/yellow light.
The wall button in fact was bad and I have purchased a new one.
