Possible Causes

Welded relay contacts on logic board, Shorted light control transistor, Miswired light circuit, Wall console light button stuck on (if equipped)

How to Fix / Troubleshooting

Safety first: Disconnect power before opening the housing. Avoid touching live terminals.

Steps to correct always-on light:

  • 1. Check wall console: If your Stanley wall console has a dedicated light button, press it to toggle the light. Ensure the button is not stuck.
  • 2. Test with bulb removed: Remove the bulb and verify that the socket is not shorted. If the light circuit still shows voltage when it should be off, the relay is likely stuck.
  • 3. Inspect logic board: Remove the cover and locate the light relay. Look for heat damage or discoloration.
  • 4. Replace logic board: Because relay replacement on the board is not typically a field repair, install a new Stanley-compatible control board to restore proper light timing.
