A closing problem that appears only in direct sunlight is useful information for diagnosis. Record the time and which side of the opening is exposed. Do not cover, disconnect or bypass the safety sensors to force the door to close.

Observe without reproducing the fault repeatedly
Tell us whether the door stops before moving or starts down and reverses. Note existing sensor indications from a safe position. A fault that happens at the same time most days should be described as a pattern, not diagnosed from one photograph.
Use the instructions for the installed system
Linear’s LDCO documentation includes sunlight at the receiver among possible sensor concerns. Other models need their own guidance. Ask the technician to evaluate alignment, connections and any manufacturer-supported solution. The goal is dependable operation with the protective system functioning.
Frequently Asked Questions
Can I tape over the receiver to keep sunlight out?
Do not block or defeat the beam. Ask for an appropriate solution for the actual sensor system.
Should I replace the opener if the issue happens only in the afternoon?
The timing does not establish that the opener is beyond repair. Have the complete symptom and sensor arrangement assessed first.
