The Atwood Mobile 93849 is an OEM replacement element power relay designed for Atwood DSI (Direct Spark Ignition) RV water heaters. This relay serves as the critical switching component that controls 110V AC power delivery to the water heater's heating element.
When the electric mode switch is activated, a 12-volt DC signal is sent via the control board's yellow wire to energize this relay. Once energized, the relay closes and routes 110V AC power to the heating element, enabling electric water heating in dual-source (gas/electric) RV water heater units.

Compatible Water Heater Models:
Atwood Mobile Products, now a Dometic brand, has been a trusted manufacturer of RV appliances and components for decades. The 93849 relay is a small but essential component — a failed relay will prevent the electric heating mode from functioning even when AC power and the control board are working properly.
