Gliderol opener’s safety beams work intermittently; sometimes the door closes, sometimes it reverses with no obstruction.

Safety first: Do not bypass beams; fix the underlying issue.

Steps to stabilise safety beams:

• 1. Tighten terminals: Re‑terminate the beam wires at both the beams and the Gliderol control board.
• 2. Secure brackets: Tighten beam mounting screws so they cannot move when bumped.
• 3. Shield from sun: If direct sunlight hits the receiver, fit a small shade or reposition slightly.
