Today’s blog will address a very common, but simple problem in the garage door industry. I get about 7-10 calls a week for photo eye related problems. Sometimes a professional is needed, but here are some simple steps a homeowner can take to possibly save a service call.
The photo-eyes (or sensors) are mounted on either side of the door near the floor. There’s an Emitter sensor and a Receiver sensor. These sensors have to “look” at each other so if they are knocked out of alignment (kids, lawn mowers, hoses, and garbage cans bumping into them can knock them out of alignment) they can’t “see” each other and the opener will refuse to close door. (Side note: if you want to override the unit you can hold the close button on the wall station until the door completely closes.) Here are some tips:
- Check & make sure sensors are aligned
- Make sure nothing is blocking sensors (garbage bag, broom, etc. – it happens more than you would think)
- Clean the lens on each sensor – sometimes dirt or grass clippings can interfere
- Check wires to the sensors & the ones going to the power head – make sure they didn’t come loose
- Check & see if sun is shining on sensors. Sometimes the sun can “blind” the sensors and cause them to think an object is blocking the opening. If this is the case the sensors may need moved further into the garage.
If you’ve tried the above mentioned tips and still have a problem with the garage door closing, then you need to give us a call. We love our customers, and always cover the basics over the phone before a service call is scheduled.
