Williams P323074 Pilot Assembly

The Williams P323074 Pilot Assembly is a critical OEM replacement component engineered specifically for high-efficiency natural gas heating systems. This natural gas pilot assembly with igniter is designed to restore factory-spec performance to Williams Comfort Products, ensuring a stable pilot flame and immediate main burner ignition. As a direct Williams furnace replacement part, it eliminates the need for field modifications, allowing for a clean drop-in installation during service calls. The P323074 pilot assembly features a precision-calibrated orifice and a durable piezo igniter lead, providing a reliable ignition sequence even in demanding residential or light commercial environments. By maintaining consistent thermocouple millivolt output, this assembly prevents nuisance lockouts and ensures the safety shut-off remains fully operational. For technicians troubleshooting frequent pilot outages or fouled igniters, migrating back to this genuine HVAC ignition component is the standard professional solution to ensure long-term system reliability and heat exchanger integrity.

Common Questions

Is the Williams P323074 compatible with propane (LP) units?
No, this specific assembly is calibrated only for natural gas heating systems. For LP conversions, a separate pilot orifice or assembly matching the specific BTU requirements of the furnace must be used.

What are the symptoms of a failing P323074 pilot assembly?
Typical failure points include a cracked ceramic insulator on the igniter, a clogged pilot orifice, or a lazy, yellow flame that fails to properly heat the thermocouple or powerpile.

Does this assembly include the thermocouple?
This part number is primarily the pilot burner assembly with igniter. Technicians should inspect the existing thermocouple or thermopile and replace them simultaneously if they show signs of oxidation or low millivolt output.
