Softener display is blank; unit appears completely dead

Safety: Use caution when working with electrical outlets. Disconnect power before removing the control cover.

Steps:

• Check outlet: Verify the outlet has power by plugging in another device. Reset any tripped breakers or GFCI outlets.
• Inspect power adapter: Whirlpool Pro Series softeners typically use a low-voltage transformer. Check for damage to the cord and plug. Ensure it is firmly plugged into both the outlet and the control.
• Measure output (if equipped): Using a multimeter, verify the transformer outputs the correct low voltage (often 24 VAC). Replace if no output.
• Check control connections: Remove the control cover and ensure the power connector is fully seated on the board.

Resolution: If the transformer is good and connections are secure but the display remains blank, replace the electronic control board.
