Safety first: Use caution when working around electrical outlets. Unplug the transformer before handling wiring.

Step-by-step checks:

• 1. Verify outlet:
  • Test the outlet with another device.
• 2. Check transformer:
  • Ensure the transformer is firmly plugged into the outlet and the low-voltage plug is fully seated in the control.
  • If available and qualified, measure transformer output (typically 24V AC). Replace if no output.
• 3. Control board:
  • If transformer output is good but display is blank, replace the electronic control board.
