Description
The Bradford White 239-49791-00 is an OEM replacement wire harness designed specifically for the Flammable Vapor (FV) Sensor Switch assembly used in Bradford White water heaters. This harness provides the critical electrical connection between the flammable vapor ignition-resistant (FVIR) sensor switch and the water heater’s control system, ensuring safe and reliable operation in compliance with ANSI flammable vapor ignition resistance standards.
Product Overview
Bradford White’s FVIR technology is engineered to prevent the ignition of flammable vapors that may accumulate near the water heater.
