Craftsman Garage Door Replacement Sensors

Replacing the sensors on your Craftsman garage door is a relatively simple task that can be completed in about an hour. By following these step-by-step instructions, you can ensure that your garage door is operating safely and efficiently.

Step 1: Gather Your Tools and Materials

Before you begin, you will need to gather the following tools and materials:

Phillips head screwdriver
New Craftsman garage door sensors
Drill or power screwdriver (optional)
Level

Step 2: Safety First

Before you start working on your garage door, be sure to disconnect the power supply to the motor. This will prevent the door from opening or closing unexpectedly while you are working. You can do this by flipping the circuit breaker or removing the fuse that powers the garage door opener.

Step 3: Locate the Existing Sensors

The sensors on your Craftsman garage door are typically located on either side of the door, about 6 inches above the ground. They are usually mounted to the wall or the door frame. Once you have located the sensors, use the Phillips head screwdriver to remove the screws that are holding them in place.

Step 4: Install the New Sensors

Take the new sensors and hold them up to the wall or door frame in the same location as the old sensors. Use the level to make sure that the sensors are level. Once you are satisfied with the placement of the sensors, use the drill or power screwdriver to drive the screws into the wall or door frame.

Step 5: Connect the Wires

Next, you will need to connect the wires from the new sensors to the wires from the garage door opener. The wires are typically color-coded, so it is important to match the colors together. Once you have connected the wires, use electrical tape to secure the connections.

Step 6: Test the Sensors

Once the sensors are installed and the wires are connected, it is time to test them. Reconnect the power supply to the garage door motor and then use the remote control to open and close the door. The sensors should prevent the door from closing if there is an obstruction in the way.

Step 7: Clean Up

Once you have tested the sensors and they are working properly, you can clean up your work area. Be sure to dispose of the old sensors and any other debris.

Troubleshooting

If you are having problems with your Craftsman garage door sensors, there are a few things you can check:

Make sure that the sensors are aligned correctly. The sensors must be aligned with each other in order to work properly.
Check the wires. The wires from the sensors to the garage door opener must be connected securely.
Replace the batteries. The sensors use batteries to power the transmitter and receiver. If the batteries are weak, the sensors may not work properly.
Contact a qualified technician. If you are unable to troubleshoot the problem yourself, you should contact a qualified technician for assistance.
