ECO thermostat (91447): monitors operating temperature and provides the thermostat control and secondary safety cutout as intended by the original equipment. Designed to operate with the original heater wiring and mounting points for reliable fit and operation. Installation Intended as a direct replacement for the listed models. Basic electrical and appliance skills recommended. Follow the heater manufacturer's service manual and safety procedures: disconnect power and gas (if applicable) before servicing. If you are unfamiliar with appliance wiring or safety testing, consult a licensed technician. We recommend viewing manufacturer or reputable tutorial videos for guidance; the parts are matched to original specifications to simplify installation. Typical use scenarios 1) Safety restoration after a thermal cutoff trip: a failed thermal cutoff to restore the heater's automatic overtemperature protection after an overheat event. 2) Component replacement during routine service: Use the kit when performing preventive maintenance or replacing worn thermostat components to maintain safe operation. 3) after diagnostic testing: the ECO thermostat and cutoff after diagnostic confirmation of a fault to the heater to normal, safe function. Important notes before ordering Please doublecheck the product images, part numbers (93866 and 91447), and the model fitment list to ensure compatibility with your heater before . Confirm you are servicing an A*wood Gas/Electric EXT water heater and one of the listed models. If unsure, compare the physical parts and part numbers on your existing thermostat assembly to the images and numbers provided. Safety reminder Always disconnect electrical power and follow proper safety procedures. If you do not have the required skills or tools, hire a qualified service technician to perform the replacement.
