Dometic RV Water Heater Parts

Dometic acquired Atwood many years ago, so if your RV has an Atwood water heater, you're in the right place. The parts here cover both legacy Atwood units and current Dometic WH series models. These water heaters run on LP gas, 120V AC electric, or both, and most failures trace back to a small set of components rather than the whole unit needing replacement.

Common repairs include replacing the ignition control board, thermostat and ECO assembly, heating element, gas control valve, electrode assembly, or thermal cut-off. We also stock anode rods, drain plugs, wiring harnesses, pressure relief valves, insect screens, and access door hardware. OEM Dometic parts are available alongside quality aftermarket options from MC Enterprises and Dinosaur Electronics.
