The AO SMITH 100293704 is a conversion kit designed to transition a 5040-series water heater from an Energy Smart electronic control system to a standard thermostat control configuration. This kit provides the necessary components to complete the control system swap at the unit level. It is intended for installation by licensed plumbers or water heater service technicians who need to revert or replace the control type on a compatible residential water heater. The conversion addresses situations where the Energy Smart control system requires replacement and a standard control setup is the preferred or available solution.
This kit applies to AO SMITH 5040-series water heaters originally equipped with the Energy Smart electronic control package. Typical install scenarios include service calls where the existing Energy Smart control board or interface has failed and a like-for-like replacement is unavailable or where a standard control configuration is operationally preferred. Installation is performed at the appliance level and does not require modifications to the water supply or flue system.
Designed as an OEM-style conversion kit for AO SMITH 5040-series water heaters equipped with the Energy Smart control system.
Installation should be performed by a licensed plumber or qualified water heater service technician. Disconnect electrical power and shut off the cold water supply to the unit before beginning any disassembly. Follow all applicable local plumbing codes and the manufacturer installation documentation included with the kit. Do not restore power or water supply until all connections have been inspected and confirmed secure.
