Lochinvar & A.O. Smith 100110788 Kit

The Lochinvar & A.O. Smith 100110788 is a critical switch and harness assembly designed for high-recovery gas-fired water heaters. As an OEM-spec component, this assembly integrates the thermal switch and specialized wiring to maintain precise communication between the burner controls and the safety limit circuits. For technicians troubleshooting intermittent ignition or lockout codes, replacing the 100110788 water heater part ensures the system accurately monitors internal temperatures and prevents thermal runaway. Constructed for durability in high-heat environments, this replacement switch and harness is essential for restoring the reliable operation of commercial and residential Lochinvar units. The plug-and-play design utilizes factory-correct HVAC wire harness connectors to eliminate high-resistance connections that often plague universal field repairs. By installing this specific Lochinvar 100110788 kit, you ensure the appliance maintains its original safety listings and operational efficiency without the risk of component mismatch.

Key Benefits:
  • Optimized Signal Integrity: High-grade copper conductors in the harness assembly reduce voltage drop and signal noise in the control circuit.
  • Direct OEM Compatibility: Engineered specifically for Lochinvar and A.O. Smith gas-fired systems, ensuring exact fit and thermal switch calibration.
  • System Protection: Actively prevents overheating by terminating the heating cycle if temperatures exceed safe operational parameters.
  • Simplified Installation: Designed for rapid field replacement with standardized connectors that match the original factory control board interface.
Common Questions:

How do I know if my 100110788 harness assembly is failing?
Failure typically manifests as inconsistent burner firing, "open limit" error codes, or visible heat damage to the wiring insulation. Multi-meter testing for continuity across the thermal switch is recommended during diagnosis.

Is this switch and harness kit compatible with other brands?
While A.O. Smith manufactures for several brands, this part is specifically validated for Lochinvar and A.O. Smith gas water heaters. Always verify your specific model number against the technical manual.

Does this assembly include the cartridge switch?
Yes, the 100110788 is a complete integrated assembly including the switch, harness, and necessary connectors for a full circuit restoration.
