Ao Smith 100306849 Combination Control Display Board

Product Description

The AO SMITH 100306849 is an OEM combination control and display board designed for residential water heater systems. This board integrates the control logic and user-facing display interface into a single unit, managing system diagnostics, temperature regulation, and operational status readouts. It is an original manufacturer component, meaning it meets the same design and performance standards as the part it replaces. Installation is typically performed by licensed plumbers or HVAC technicians during routine service or component failure repair.

The 100306849 is suited for residential water heater applications where the original combination control display board has failed or requires replacement. Because it is an OEM part, it is engineered to fit the original mounting configuration and wiring harness without modification. Technicians servicing AO Smith water heater units will find this board a direct drop-in replacement for the factory-installed control assembly.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Always disconnect power to the water heater and shut off the gas supply, if applicable, before removing the existing control board. Handle the board by its edges to avoid damage to electronic components, and verify all wiring connections are fully seated before restoring power. Consult local plumbing and mechanical codes for any jurisdiction-specific service requirements.
