I have a Stanly Opener that will only work when holding the wall mounted switch. Beam sensor appears to be working ok, but light flashes to indicate a fault (not referenced in ops manual). Tried calling 1-800-521-5262, constantly busy. Tried calling local dealers, no one knows how to get in touch with Stanley. Finally found someone on web that told me to call Innovative Home Products 877-723-1088. Couldn't speak to anyone, received an endless string of prompts (press one to hear.....) that ultimately led me back to 800-521-5262. Completely frustrated now, must be nice that Innovative Home Products has so much business rolling in that they can't support their current customers.
