Opener light does not turn on when door operates.

Safety first: Disconnect power before changing bulbs or touching the socket.

Steps:

• Replace bulb: Install a new bulb of the correct wattage and type recommended by Henderson.
• Check socket: Inspect the light socket for corrosion or heat damage. Gently bend the center contact up slightly if it is flattened.
• Test with known‑good bulb: If the new bulb does not work, the light relay or triac on the Henderson control PCB may have failed. Replace the board if light function is required.
