Dometic 9610008168 DFMDH30121 Essential Medium 30,000 BTU Doorless RV Propane Furnace

The Dometic DFMDH30121 is the Essential Series doorless version of Dometic's DFMDH30 medium furnace, delivering 30,000 BTU of propane-powered forced-air heat for RVs, travel trailers, camper vans, and similar applications. As a doorless model, it installs without requiring an exterior access door, eliminating the need to cut a large opening in the sidewall of the vehicle and allowing servicing from inside the RV instead.

The DFMDH30121 is part of Dometic's upgraded Essential Series, featuring several key advancements over previous-generation Atwood/Mojave furnaces, including a patent-pending Hall Effect Sensor ignition system and integrated Soft Start technology for more reliable, quieter startups.

Key Features:

• 30,000 BTU output — powerful propane heating for medium-sized RV living spaces
• Doorless design — no exterior access door required; unit is serviced from inside the RV
• Hall Effect Sensor ignition — automotive-grade, debris-resistant ignition for dependable starts
• Integrated Soft Start — reduces in-rush current by up to 80%, resulting in quieter and smoother startups
• 18–22% more airflow — advanced air baffle system distributes heat more evenly throughout the space
• One-piece tubular heat exchanger — seamless, weld-free construction maximizes air distribution and long-term durability
• Radius tubing — promotes smooth airflow and reduces turbulence for quieter operation
• 12V DC powered — compatible with standard RV electrical systems
• LP gas (propane) fuel type
• Low-profile, compact design — approximately 7-3/8 in. H x 16-1/2 in. W x 20 in. D
• Installs horizontally or vertically for flexible placement

The DFMDH30121 is well-suited for travel trailers, fifth wheels, and motorhomes where a mid-range BTU furnace is needed and a clean, doorless installation is preferred. The thermostat and access door (if desired) are sold separately. Professional installation by a qualified technician is recommended, as this unit operates on propane gas.
