Garage Door Sensor Repair in Amherst, MA

Garage door sensor repair in Amherst

A door that will not close is an open door. That is a security problem overnight, and a heating problem in a January cold snap. The common shortcut is worse. People twist the two sensor wires together to force the door down. That deletes the entire reversing system. Anything under the door (a kid, a dog, a bicycle) stops the door only after it is crushed. Photo eyes sit within six inches of the slab by federal opener rules, so they catch what is low to the ground.

Most failures here are not the eyes themselves. Frost heave lifts the slab and tilts the brackets out of aim. Snowbanks pushed in against an open door shove one eye off line. Plow spray and road salt creep up the bell wire and corrode the splices. On south- and west-facing openings, low sun can wash out the receiver in the afternoon only.

Check it yourself first. Look at the two indicator lights. A dark or flickering light means broken beam or broken wire. Wipe both lenses. Sight down the beam line.

Insulated 16x7 sectionals on post-1970 attached garages usually have wire stapled along the jamb, easy to trace. Older detached garages on 8x7 and 9x7 doors often have splices buried behind trim. That run decides whether this is a bracket job or a rewire.
