The AO SMITH 100110860 is a power harness kit designed to restore or replace the internal wiring harness that routes electrical power within a water heater unit. This kit provides the necessary wiring connections to ensure proper communication and power delivery between components such as the control board, heating elements, and other electrical assemblies. It is typically installed by licensed plumbers or HVAC technicians during a service call when the original harness shows signs of damage, corrosion, or failure. Replacing the harness with an OEM-spec kit helps maintain safe and reliable water heater operation.
This power harness kit is suited for use in residential water heater applications where the existing wiring harness has become compromised. It is intended for use during repairs where the power distribution wiring within the unit must be restored to factory condition. Installers working on AO SMITH water heater systems will find this kit a direct service replacement for the original harness assembly.
Designed as an OEM-style replacement power harness kit for AO SMITH water heater systems. Consult the equipment service manual or AO SMITH technical support to confirm fitment for a specific model before installation.
Installation should be performed by a licensed plumber or qualified water heater service technician. Disconnect all electrical power to the unit at the breaker before beginning any wiring harness replacement work. Verify that the replacement harness connectors match the existing terminals before finalizing the installation. Follow all applicable local electrical codes and manufacturer service instructions throughout the procedure.
