Garage Door Opener



Question:
I have a Stanley opener that is acting up. Checked the beam sensor and they work on other door. This one will open a foot then stop, then it may go a foot again. You can hear what sound like a relay opening and closing coming from the main unit control board. The buttons that control the door are disconnected. The light doesn't come on like if the opener stops. Anybody have a guess what to check next. This morning it worked fine. Last night and now this afternoon stopped.

Answer:
If the door works by hand I would suspect one or more of the plastic parts are broken inside. Take the cover off & it should be obvious. Also sounds like your light bulbs are burnt out, since the clicking relay is probably the one that controls the light. The lights flash whenever the unit goes into overload. The overload cam (on the bottom of the drive shaft) trips a micro-switch whenever the door hits anything or when there is too much load being put on the operator. Parts are very difficult to find & you will be better off replacing the unit.
