RV Furnace Parts & Accessories

Which RV furnace parts fit Atwood and Hydro Flame models?

This collection covers replacement parts for Atwood, Hydro Flame, and Suburban furnaces, including sail switches, control boards (also called circuit boards or modules), igniters, blower motors, limit switches, and gas valves. Atwood and Hydro Flame share many part numbers since Atwood acquired the Hydro Flame line, so a part listed for one often fits the other. Confirm your furnace model and serial number before ordering to make sure the part matches your specific unit.

How do I know if I need a new sail switch, control board, or igniter?

The symptom usually points to the part. A furnace that runs the blower but never ignites typically has a failed sail switch or igniter. A furnace that does nothing when the thermostat calls for heat usually has a bad control board or blown thermal fuse. A unit that lights briefly then shuts down often points to a dirty flame sensor or weak igniter. For broader 12-volt diagnostics, the RV Electronics collection covers fuses, relays, and converters that can also affect furnace operation.

Are these OEM parts or aftermarket replacements?

The collection includes both. Original Dinosaur Electronics boards and Atwood/Suburban OEM components sit alongside quality aftermarket sail switches, motors, and igniters. Each product page lists the manufacturer and any cross-reference numbers it replaces, so you can match a legacy part number directly. If you are sourcing multiple components during a system refresh, the RV winterization essentials collection pairs well for fall maintenance.

Can I replace an RV furnace motor myself?

Yes, blower motor replacement is a common DIY repair on Atwood, Hydro Flame, and Suburban furnaces. The motor pulls out with the burner assembly after disconnecting the gas line, 12-volt leads, and mounting screws. Plan on 60 to 90 minutes for a first-time job, and replace the sail switch at the same time if the original shows soot or wear. Text or call 817-984-1852 if you need help confirming the correct motor for your furnace model.

Does United RV Parts offer free shipping on furnace parts?

Yes. Orders over $100 ship free within the contiguous United States. Most furnace control boards, sail switches, and igniters ship the same or next business day from in-stock inventory.
