Rheem-Ruud SP20127 Pilot Assembly

The Rheem-Ruud SP20127 Pilot Assembly is a critical replacement component designed for high-efficiency natural gas water heaters. This OEM pilot assembly serves as the direct successor to the AP14317B-1, ensuring a seamless fit and electrical compatibility with existing gas control valves. Precision-engineered for consistent ignition, this pilot burner assembly includes the integrated thermopile and thermocouple leads necessary to maintain a reliable pilot flame and safety circuit. When diagnosing water heater pilot light won't stay lit issues, replacing the entire assembly eliminates intermittent failures caused by oxidation or sensor degradation. It is built to withstand high combustion chamber temperatures while providing the millivolt signal required for the gas valve to operate Rheem-Ruud gas water heaters safely. Selecting this genuine Rheem replacement part ensures the unit meets original manufacturer specifications for flame stability and ignition timing, preventing frequent service calls and ensuring long-term operational uptime for commercial and residential installations.

• Direct Replacement Compatibility: Specifically engineered to replace AP14317B-1 without the need for mounting bracket modifications.
• Enhanced Ignition Reliability: Optimized natural gas burner orifice ensures a stable flame for consistent sensor heating.
• Integrated Safety Sensors: Includes high-quality thermopile components for accurate millivolt output to the gas controller.
• Durable Construction: Built with high-grade alloys to resist corrosion and thermal stress within the combustion chamber.
• Simplified Installation: Features pre-terminated leads that match Rheem-Ruud wiring harnesses for faster field service.

Is the SP20127 compatible with LP gas units?
No, this specific assembly is calibrated for natural gas water heaters. Using this in a liquid propane system will result in improper combustion and potential safety hazards.

Will this fix a water heater that won't stay lit?
If the gas valve is functional but the pilot flame is weak or the thermocouple is failing to hold the magnet open, replacing this assembly is the standard professional solution.

Are there specific tools required for this replacement?
Standard HVAC hand tools, including a 7/16" and 3/8" open-end wrench, are typically required to disconnect the pilot tube and sensor leads from the gas valve.
