My Mother In Law recently passed away and we acquired her home in Northern Arizona. It came with a Heatilator pellet stove which was working great until last week. Seems as though the auger motor is no longer working. This stove was installed in 1990 and I need help locating a new motor. I called a company in Prescott Arizona, and they told me that Heatilator only made this stove for a year or two. The numbers off the motor are: ECM 5817 9/90 120V 60 Hz 1 RPM .55 AMP MOD 734. The model number from the stove is SX. Growing up in Phoenix, my husband and I know nothing about pellet stoves. Any help would be greatly appreciated.
