Description
The Rheem-Ruud AP15172 is an OEM replacement flammable vapor sensor (FVS) harness designed to restore the flammable vapor ignition resistance (FVIR) safety system in compatible Rheem and Ruud water heaters and HVAC appliances. This harness connects the flammable vapor sensor to the control system, enabling the unit to detect the presence of flammable vapors near the appliance and shut down operation before ignition can occur — a critical safety function required by current ANSI and ASHRAE standards.
Key Features

Why Replace the FVS Harness?
A damaged, corroded, or broken flammable vapor sensor harness can cause nuisance lockouts, prevent the appliance from operating, or — more critically — disable the FVIR safety system entirely. Using a genuine OEM harness from Rheem-Ruud ensures the sensor circuit maintains proper continuity and the safety system performs as designed.
