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. Thanks Barry
