Ao Smith 100111741 Sse Control Board Kit

Product Description

The AO SMITH 100111741 is a single-element control board kit designed for SSE-series electric water heaters. The kit integrates an on-off switching function with a low water cutoff (LWCO) safety control, providing both operational management and protection against dry-fire conditions in a single assembly. Licensed plumbers and water heater technicians install this kit as a direct service component when restoring proper control and safety function to a unit. It is a factory-specified assembly intended to return the heater to OEM operating standards.

This control board kit is suited for residential and light commercial SSE-series electric water heater applications where a single-element heating configuration is used. The LWCO feature is critical in installations where low water pressure or intermittent supply is a concern, as it cuts power to the element before a dry-fire condition can occur. Service technicians use this kit during board-level replacement when troubleshooting control or safety circuit failures.

Key Features

• Integrated on-off switching control and low water cutoff (LWCO) in one kit

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician. Disconnect electrical power to the water heater at the breaker before removing the existing control board or handling any wiring. Verify the water supply is fully charged to the tank before restoring power, as the LWCO circuit requires adequate water presence to allow element operation. Follow all applicable local electrical codes and manufacturer service documentation during installation.
