Description

This is a motor only and will fit into the existing housing of your stove or insert. Early versions of this motor were variable speed and would have had four wires; Red, Blue White, and Black. Harman always wired this blower for maximum output at line voltage using ONLY the Black and White wires. Requires two (2) 1/4" female wire terminals (not included) to be crimped to the wire leads at the time of installation.

Harman Product Bulletin: March 15, 2011

The replacement blowers for the Super Magnum Stoker, Invincible, and Accentra pellet inserts are now one-speed blowers. Previously these replacement blowers were three-speed with two speeds made inactive. (Red and Blue not connected) All production models beginning with serial number 008600509 for the Super Magnum Stoker and serial number 008248445 for the Accentra pellet insert have been changed to the one-speed blower. This new wiring is invisible to the consumer since it still only operates at one speed like it always had.

  • If the serial number on your Harman Invincible Insert falls between serial number 1556 - 2128, this blower is not compatible with your stove. During that time Harman was using part number 3-21-08619. This part is now obsolete.
  • Wire Connectors Link, requires QTY (2)
  • A motor only replacement requires the fan to be swapped from the old motor to the new one. If you need a new fan you need to order the whole assembly, 3-21-47120
  • The blower for the Super Magnum Coal Stoker was optional. If you do not have the blower but would like it, order the full OEM assembly, part 3-21-47120.

  • does the new motor come with a adaptor ring for the stove ?

    For the Harman Accentra Insert Distribution motor, part number 12189M (motor only), you will not need an adaptor ring. The mounting arms are the same length as the OEM motor that you are replacing. S

  • what is the small rectangular box attached to the motor, and what does it do? my blower motor does not have this appendage.
