2. Photo Eye Sensors

Garage door openers are equipped with photo eye sensors that ensure the door doesn’t close on objects or people. If these sensors are misaligned or obstructed, they can prevent the door from operating properly.

  • Alignment Issues: Ensure that the photo eye sensors are aligned and facing each other. If they are knocked out of place, the door may not close.
  • Dirt or Obstruction: Check for dirt, dust, or other debris on the sensors. Clean them gently with a soft cloth to ensure proper function.

3. Limit Settings

Your Craftsman garage door opener has limit settings that dictate how far the door travels when opening or closing. If these settings are misconfigured, it can lead to intermittent operation.

Like any mechanical device, garage door openers can wear out over time. Look for the following signs of wear and tear:

  • Worn Gears: If the gears inside the opener are worn, they may need replacement. Listen for unusual sounds during operation as a potential indicator.
  • Chain or Belt Issues: For chain or belt drive openers, inspect the chain or belt for signs of wear or slack. A loose or damaged belt can cause intermittent function.
