Direct-replacement internal furnace core that slides into an existing SF-20F or SF-20FQ cabinet, restoring furnace performance without replacing the whole unit.
The Suburban Mfg 2606A (model RP-20FQ) is a replacement furnace core built for the Suburban SF-20F and SF-20FQ series furnaces. Rather than laboriously removing and repairing individual internal furnace parts - or replacing the entire furnace and its exterior installation components - this core lets you swap in the entire internal burner and heat exchanger assembly while reusing the existing cabinet and exterior venting already installed in the RV. It's manufactured to Suburban's original specifications for a reliable, direct OEM fit.
This core is designed specifically for SF-20F and SF-20FQ series furnaces. Suburban offers similar replacement cores sized for other furnace models and BTU ratings (for example, the RP-20Q core, part #2605A, for SF-20/SF-20Q furnaces), so confirm the exact furnace model before ordering.
