The Atwood Mobile 91873 is a replacement Thermostat and E.C.O. (Energy Cut-Off) kit designed for Atwood 110-volt AC electric RV water heaters. This two-component kit provides both temperature regulation and high-limit overheat protection, keeping your RV water heater operating safely and efficiently.
The thermostat uses a thermo disc style, back-mount design and is rated for single-element, 110 VAC systems. The integrated E.C.O. (Energy Cut-Off) device acts as a high-temperature reset shut-off, automatically cutting power to the heating element if water temperature reaches an unsafe level — an essential safety feature for any electric water heater.
