The Atwood Mobile 93849 is an OEM replacement power relay designed for Atwood DSI (Direct Spark Ignition) RV water heaters. This relay serves as the critical electrical switching component that controls 110V AC power delivery to the water heater's heating element.
When the electric mode switch is activated, the control board sends 12V DC power through the yellow signal wire to energize this relay. Once energized, the relay closes and routes 120V AC power directly to the heating element, enabling electric-mode water heating in your RV.
