Lochinvar & A.O. Smith 100327085 Pilot Assembly

The Lochinvar & A.O. Smith 100327085 Pilot Assembly is a critical OEM component designed for high-performance natural gas water heater and boiler systems. Specifically engineered to maintain a stable standing pilot light, this assembly ensures consistent burner ignition and reliable flame rectification across residential and commercial platforms. As the direct replacement for 100165804 (formerly PLT1017), this part integrates the thermocouple, pilot tube, and spark igniter into a single, durable housing to streamline field repairs. For technicians troubleshooting ignition failure or erratic flame signals, this assembly provides the precision required for tight tolerances in modern combustion chambers. This genuine OEM replacement part is built to withstand high-temperature environments, preventing the premature degradation often seen in aftermarket alternatives. Proper installation involves secure compression nut seating and terminal connection to the gas valve to ensure safety circuit continuity. Rely on this factory-spec pilot burner assembly to restore system efficiency and meet manufacturer-specific operational requirements.

• Universal Compatibility: Serves as the factory-authorized direct replacement for 100165804, ensuring a perfect fit without field modifications.
• Natural Gas Optimization: Specifically calibrated for natural gas water heater and boiler applications to maintain optimal flame characteristics.
• Integrated Reliability: Consolidates the thermocouple and pilot burner into a rugged assembly for improved durability under heavy thermal load.
• Contractor Grade: Designed for an easy installation process, reducing labor time during service calls for ignition-related diagnostics.

Is the 100327085 compatible with older PLT1017 models?
Yes, this pilot assembly is the current manufacturer-recommended upgrade and direct replacement for 100165804 and the older PLT1017 part numbers.

What are the signs that the pilot assembly needs replacement?
Technicians should look for a pilot that will not stay lit, heavy carbon buildup on the thermocouple, or a weak standing pilot light that fails to bridge to the main burner.

Can this unit be used for Propane (LP) systems?
This specific part is configured for natural gas. Always verify the orifice size and gas type of the existing appliance before installation to ensure safe combustion.
