Potential Issues

Before replacing the control center, inspect the 12V power supply, wiring harness, connectors, ground connections, and water heater control board. A blank or unresponsive display can also be caused by wiring or power issues rather than a failed control center.

Check the wiring between the control center and the water heater for loose connections, corrosion, or damaged wires before replacing the controller.
