Autotrol softener display is blank and unit is completely unresponsive

Safety: Use caution when working around electrical outlets.

• Check outlet: Test the wall outlet with another device to confirm power is present.
• Test transformer: Measure the output of the Autotrol transformer (typically 24 VAC). Replace the 24 VAC transformer if no output.
• Inspect low-voltage plug: Ensure the transformer plug is fully inserted into the control head and that the cord is not damaged.
• Internal fuse/board: If power is present at the control but the display is dead, the internal fuse or control board may be blown. Replace the control module as an assembly.
