How to Adjust Sensor Eyes on Garage Doors

How to Adjust Sensor Eyes on Garage Doors

While a lot of repairs your garage door might need aren’t possible for you to do on your own, adjusting the sensor eye is one that has little to no risk involved. We’ll walk you through this step-by-step.

Step 1: Where the Sensors are Located

You can find your garage door’s safety sensors in one of two places. They’ll either be on the rails of the door close to the floor or on the door itself. They’re most commonly found mounted to the rail of the door.

Step 2: Checking the Sensor Beams

It’s crucial that you don’t check the sensor with your own body. Instead, use something that you won’t mind getting damaged. You can use a clean cloth to clean the sensor. Be sure to wipe the sensor gently; don’t handle them more than necessary, as you could risk knocking them out of alignment.

Step 3: Checking the Wires

If your sensor gets knocked or banged, it can cause your wire to snap, come adrift, or just cause a slight misconnection. Misconnections can cause your sensor to work sometimes and appear broken others. If the wires are broken, you can unplug the unit from the outline and fix them with a soldering iron.

Step 4: Checking the Operator Batteries

If it still doesn’t work, have you considered checking the batteries in the control operator? People commonly forget that the garage door operates needs batteries to function properly; your problem could be as simple as that.

Step 5: Use the Force Adjustment Switch

If you get to the point that nothing else has worked, maybe it’s the wear and tear of the years taking their toll on the springs. Located behind your right sensor, under the light is the force adjustment switch. Turn it just a fraction – very, very slightly – and then test your garage door once more. Be sure to use an object that you wouldn’t mind being destroyed, like a cardboard box, to test it.

Step 6: Calling in the Reinforcements

If, after all of this, you still can’t pinpoint the problem, it’s time to place it in the hands of those more capable. Garage doors are very heavy objects held in place by wires and springs under an incredible amount of tension and pressure; it can be very dangerous to mess around with when you don’t know what you’re doing. Always remember safety first and foremost.

A lot of repairs garage doors require over the years aren’t capable of being handled by amateurs, given the dangerous nature and sensitive construction of the garage door. However, the sensor eye is something you may be able to fix yourself. We hope this step-by-step guide has helped you to identify and resolve whatever issue you were having with your sensor, or at least help you to confidently say that you need a repairman.
