the M0081904R utilizes a permanent magnet rotor to provide superior torque and energy savings over traditional PSC motors

regulating the ionization process required to capture airborne particulates

It is chemically identical to and directly replaces model variations MA-5210-0-0-2

allowing for targeted cleaning or replacement of the flame rod rather than trial-and-error part swapping

While it is a genuine Goodman Amana part
