Gliderol garage door opener light does not turn on when the door operates, but the opener otherwise works normally.

Safety first: Turn off power before changing bulbs or touching the lamp holder.

Steps to restore light:

• 1. Replace bulb: Fit a new bulb of the correct type and wattage recommended by Gliderol.
• 2. Inspect socket: Check for corrosion or heat damage; clean contacts or replace socket if necessary.
• 3. Check wiring: Ensure the two light wires are firmly connected to the control board terminals.
