Atwood Mobile 91547 ECO Thermostat & T-Stat Service Kit for XT Series RV Water Heaters

The Atwood Mobile 91547 is a front-mount ECO and Thermostat (T-Stat) Service Kit engineered specifically for Atwood XT Series RV water heaters. This OEM replacement kit restores proper temperature regulation and high-temperature safety protection to keep your water heater operating safely and efficiently.

The Energy Cut-Off (ECO) thermostat functions as a normally closed switch that supplies voltage to the solenoid valve during standard operation. If water temperature exceeds the safe threshold of 180°F, the switch opens automatically, cutting off gas flow and protecting the water heater from heat damage. A common symptom of a failed ECO thermostat is an ignition spark with no gas flow — replacing this kit resolves that issue.

Key Features:

• Front-mount ECO and thermostat combination service kit
• High-temperature shut-off activates at 180°F to prevent water heater damage
• OEM Atwood/Dometic replacement part — direct fit, no modifications required
• Designed for single-element Atwood XT Series water heaters

• Includes 90-day parts warranty through Atwood
