The Furrion Replacement Pilot Flame assembly (Part #[phone removed]) is the correct and compatible igniter assembly for the FSRE21SA-SS oven model. This OEM-quality part includes the complete pilot light assembly with the spark electrode, thermocouple, and gas pilot tube. The mounting bracket is the same, ensuring proper fit and function. When installing, handle the thin copper thermocouple wire with care to avoid sharp bends or kinks, which can prevent the oven from staying lit. You can purchase this replacement part directly from Elkhart RV Parts for reliable performance.
