Designed as a direct supersession for \u003cstrong\u003eAP13447-3\u003c\/strong\u003e, this \u003cstrong\u003eflammable vapor sensor\u003c\/strong\u003e (FVS) monitors the environment for volatile substances, triggering a safe shutdown via the \u003cstrong\u003egas control valve\u003c\/strong\u003e if high concentrations are detected. A common indicator for a malfunctioning or tripped sensor is the \u003cstrong\u003eseven-flash error code\u003c\/strong\u003e (7-3 lockout) on the status light. Unlike standard thermistors, this sensor requires a specific \u003cstrong\u003eresistance level\u003c\/strong\u003e—typically 13k ohms or higher—to allow the burner to fire. Installation of the \u003cstrong\u003eSP20172 water heater sensor\u003c\/strong\u003e restores safety protocols and prevents nuisance lockouts caused by moisture or environmental contaminants. This kit includes the necessary \u003cstrong\u003eFV sensor assembly\u003c\/strong\u003e, terminal connectors, and a cap plug to ensure a secure, sealed interface with the existing harness on models like the PDV40 and PDV50 series.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits:\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCritical Safety Compliance:\u003c\/strong\u003e Restores \u003cstrong\u003eFVIR safety\u003c\/strong\u003e standards by detecting volatile gases to prevent accidental ignition.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect Drop-in Replacement:\u003c\/strong\u003e Identical to \u003cstrong\u003eAP13447-3\u003c\/strong\u003e and \u003cstrong\u003eAP19452\u003c\/strong\u003e, ensuring seamless integration with original \u003cstrong\u003eRheem-Ruud\u003c\/strong\u003e gas valves.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTroubleshooting Solution:\u003c\/strong\u003e Specifically engineered to resolve \u003cstrong\u003esoft lockout\u003c\/strong\u003e conditions and persistent 7-light pulse error codes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision Resistance:\u003c\/strong\u003e Factory-calibrated to meet the exact \u003cstrong\u003etechnical specifications\u003c\/strong\u003e required for modern digital gas controls.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know if the SP20172 needs replacement?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf your \u003cstrong\u003ewater heater status light\u003c\/strong\u003e flashes seven times with a three-second pause, the gas valve has detected an \u003cstrong\u003eFV sensor lockout\u003c\/strong\u003e. Use a multi-meter to check the \u003cstrong\u003eresistance\u003c\/strong\u003e; if it reads below 13k ohms or shows an open circuit, the sensor is likely compromised and requires replacement.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I reset the sensor after it trips?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile some \u003cstrong\u003egas valves\u003c\/strong\u003e allow for a manual reset sequence (cycling the temperature dial), the manufacturer recommends total replacement of the \u003cstrong\u003eSP20172 kit\u003c\/strong\u003e if the sensor was physically exposed to high concentrations of flammable vapors or high moisture to maintain system integrity.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhich models are compatible with this kit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis \u003cstrong\u003eHVACR\u003c\/strong\u003e specialized part is compatible with various \u003cstrong\u003eRheem, Ruud, and Richmond\u003c\/strong\u003e residential gas water heaters, particularly power vent (PDV) and atmospheric models manufactured after 2019 that utilize the updated \u003cstrong\u003eFV sensor\u003c\/strong\u003e resistance profiles.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
