My garage door question has to deal with the safety beam. It has been real cold here lately, so my dog has had to stay in the garage instead of outside while we are at work. The other day my dog chewed up the wire and the connector piece for one side of the safety beam. Therefor, the safety beams circuit has been cut, and the door will not close now. I am looking for suggestions to fix my broken garage door beam. The garage door brand is "Builders Opener". Thank you very much. Aaron Wenburg
