Chamberlain Stuck Light Relay or Misconfigured Light Timer

Opener light stays on constantly and will not turn off.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed relay on logic board, Wall control light button stuck, myQ app light control left ON, Timer-to-close/light settings

Safety first: Unplug the opener before opening the housing. Avoid touching live circuits.

Steps to fix:

Check wall control: Press the light button to toggle the light. Ensure the button is not stuck.
Check myQ app: If using myQ, verify the light is not commanded ON in the app.
Power cycle: Unplug the opener for 1 minute, then plug back in. If the light comes on immediately and stays on, the relay is likely stuck.
Replace logic board: A stuck light relay requires logic board replacement.
