3 Repair Tips for Garage Door Photo Eyes


Filed under: Garage Maintenance

Photoelectric sensors, or photo eyes, are an innovative addition to garage door safety. They consist of two main parts: a transmitter and receiver placed low to the ground on both sides of your garage door. The transmitter projects an invisible beam of light to the receiver. If the beam is interrupted when the door is closing, it will trigger a system response to stop closing the door and return to the fully open position.

Sometimes this ingenious little piece of technology will stop functioning. The reasons vary, but usually it’s a simple fix. If your photo eye system isn’t working right, here are three things you can try to repair the problem:Precision Garage - 3 Repair Tips for Garage Door Photo Eyes

  1. Align the Sensors – The transmitter and receiver are generally mounted down low, just outside the garage door track. This makes them vulnerable to getting bumped on occasion by things like a bike tire, or the brush of someone’s foot. You can correct the problem by realigning the component eyes by hand. You can do this visually or use a measuring tape and level for accuracy, if needed.
  2. Clean the Lens – Garages get dusty and dirty, especially at ground level. If your photo sensors aren’t sensing, it may be just as simple as wiping down the lens eyes. Use a clean micro cloth and glass cleaning solution. Be careful to avoid scratching the lens.
  3. Shade the Photo Eyes – Occasionally, some homeowners note that their garage won’t close at certain times of the day. If this is the case, it could be sunlight blinding your photo eyes. For this particular problem, you may need a tech to help you install a sun shield over your lenses.

You can always test your photo eye by pressing the wall button or garage remote to activate the door closing sequence. If the garage door successfully closes, it means the photo eye problem is resolved, and you’re back in business as usual. However, just to be sure, go and disrupt the beam as the door is closing. The door should reverse back open.
