My craftsman garage door sensor receiver not works time by time, may because of the winter cold? I opened the receiver's box and plugged into the connector, the green led is on, disappear after few times open and close test. Should I buy a set of new sensor or fixable? Or is it OK to exchange the left right side of transmitter and receiver?
