Kolter Homeowner Guide

4. Check the garage door owner’s manual for instructions on conducting the reversal test and for making necessary adjustments.

SERVICE TIP: If the door still fails to reverse have it serviced by a professional. Until it’s repaired, close the door and disconnect it from the opener. Don’t use it until it’s repaired.

Checking the photocells The photocells on your garage door are located on either side, about five inches above the floor. They project a light beam from one side to the other. Check them monthly.

On properly functioning photocells, there is one constant red light and one constant green light.

On improperly functioning photocells, there is one flashing red light. Common reasons include non-aligned beams, a loose wire, or a blocked beam. If the beam is broken and you use the remove control or wall button to shut the door, it will reverse. The door will close if you hold the button until it’s fully closed but that doesn’t solve the issue. Clear the lens of the photocell of anything that may be obstructing it such as cobwebs or leaves. Contact a professional if the problem persists.

5. Repeat the first two steps after making the proper adjustments. The door should reverse immediately upon contacting the wood.
