Decko opener light does not turn on during operation or when using light button.

Safety first: Unplug the opener before changing bulbs or inspecting the socket.

Check bulb:

• Replace the bulb with a new, opener-rated bulb of the correct wattage (often 60W or less, or LED equivalent).
• Avoid CFL bulbs; use LED bulbs marked as garage-door-opener compatible.

Inspect socket:

• Look for corrosion or burned contacts inside the socket.
• Gently bend the center contact tab upward slightly (with power off) to ensure good contact with the bulb base.

Test light function:

• Restore power and press the light button on the wall control (if equipped).
• If the bulb and socket are good but the light never turns on, the light relay on the control board may be defective and the board may need replacement.
