Product Overview

The Dometic™ Atwood 33301 OEM Heat Exchanger is a genuine factory replacement heat exchanger designed specifically for DFM Series medium RV furnaces.

The heat exchanger is one of the most critical components in an RV furnace. It transfers heat from the combustion chamber into the airflow system while keeping exhaust gases completely separated from the interior air supply. A damaged or cracked heat exchanger can lead to furnace shutdowns, poor heating performance, and potentially unsafe operation.

Replacing a compromised heat exchanger with OEM Part 33301 restores safe heat transfer, proper furnace efficiency, and reliable operation.

Manufactured to Dometic’s original equipment specifications, this heat exchanger ensures precise fitment and long-term durability.

Please Note: This is a Special Order item and typically ships within 7–14 business days.
