Suburban Furnace SF-Q Access Doors

What is the Suburban SF-Q furnace access door?

The access door is the exterior panel that covers the SF-Q furnace burner compartment on the sidewall of your RV. It provides combustion air intake, exhaust venting, and service access to the burner assembly. Replacing a damaged or warped door restores a proper seal and protects the furnace internals from road debris and weather.

Which Suburban furnace models use the SF-Q access door?

The SF-Q series access doors fit Suburban SF-20Q, SF-25Q, SF-30Q, SF-35Q, and SF-42Q furnaces. The Q designation indicates the quiet-series models. Always confirm your furnace model number on the rating plate inside the burner compartment before ordering, since door dimensions vary by BTU rating.

How do I install a replacement SF-Q access door?

Remove the screws around the perimeter of the existing door, disconnect any wiring harness if equipped, and lift the door away from the sidewall opening. Transfer the gasket or apply fresh sealant per the Suburban service manual, position the new door, and reinstall the screws. The job takes about 20 minutes with a standard Phillips driver. If your furnace also needs internal parts, see our 10 gallon RV water heater and RV winterizing kits collections for related cold-weather components.
