Sensors on the Craftsman garage door opener provide safety and are required for the proper operation of the opener. If the old wiring has become corroded or damaged, you can replace it with new wires rather than purchasing another sensor kit. The sensors cannot be opened, so you will be cutting and splicing wire. If the damage is in the sensor, the sensors will have to be replaced. Does this Spark an idea?
Instructions
1. Disconnect the power to the garage door opener by either unplugging it from the ceiling electrical outlet or by turning it off at the circuit breaker.
2. Remove the plastic lens door on the right side of the Craftsman garage door opener by inserting a small flat-head screwdriver between the motor head and the cap. Carefully unsnap the lens cap and move it out of the way.
3. Disconnect the sensor wires from the quick connect terminals by pushing in on each terminal and pulling the wire out. There will be two black wires and two white wires.
4. Cut the wire 8-inches from the safety sensors using wire strippers. Trim the insulation 7/16-inch from the ends of the wire still connected to the sensors using wire stripper.
5. Measure from the floor to the ceiling using a tape measure. Then measure from the garage door to the opener head. Add those two measurements together and add another 24-inch. This is the length you need to cut the low voltage bell wire for each sensor.
6. Remove 7/16-inch of insulation from one end of the replacement bell wire using wire strippers. Twist the black wire together with the black wire from the sensor using a plastic wire cap. Twist the white wire together with the white wire coming from the sensor using a plastic wire cap as well.
7. Tack the wire to the outside jamb using insulated staples and a hammer. Be careful not to pierce the wire with the staple. Continue attaching the wire to the jamb all the way to the ceiling using insulated staples at every 18-inches. From the ceiling, tack the wire directly above the center of the door. From the front center run the wire straight back to the opener head tacking the wire at every 18-inches to the ceiling.
8. Repeat the wiring process for the opposite side sensor. Allow the wire to hang from ceiling to just below the opener head and cut off the excess with wire strippers.
9. Remove 7/16-inch of insulation from the ends of the wire. Twist the two black wires together and then twist the two wire wires together. Insert the wires into the appropriate quick connect terminal.
10. Restore the power to the garage door opener by either plugging it back into the ceiling outlet or turning on the circuit breaker.
