Lochinvar L100167803 Integrated Control

Product Description

The LOCHINVAR L100167803 is an integrated control unit designed for use in Lochinvar heating equipment. Integrated controls consolidate burner sequencing, ignition management, limit monitoring, and system safety functions into a single board assembly. This component serves as the operational brain of the appliance, coordinating inputs from sensors and thermostats to manage fuel delivery and ignition timing. Licensed HVAC technicians and boiler service professionals are the primary installers of this type of control. Its replacement restores full factory control logic to the heating unit.

The L100167803 is suited for residential and light commercial Lochinvar heating applications where the original integrated control has failed or been flagged during service inspection. Integrated controls of this type are commonly found in gas-fired boilers and water heaters. Installation typically takes place during a scheduled service call or as part of a warranty repair. No specific compatible model numbers were provided in the available product data.
