Assembly Instructions For Harman Distribution Blower Fits The Accentra Insert (2003-2012) 3-21-47120-AMP

Accessing the distribution blower on the Harman Accentra (2003-2012) can be a challenge. It is located under the unit. I've found that the easiest way is to pull the stove out from rack, lay a bag of pellets on the floor in front of the hearth, after disconnecting the brown, white and green wires from the power supply and disconnecting the room sensing probe, simply allow the stove to fall forward on the pellets (across the door). You can then access the blower from bottom.

Right part at right price. Thanks!


I bought the blower from another website and had to return it because they sent me the wrong one and kept telling me to wait until they get it in stock again
Ordered the blower from you guys and the right one came and came promptly


As described. Quick, detailed service and part was perfect. Great experience!

Perfect fit.

It was exactly what I needed perfect fit, and very fast just normal shipping, Thanks guys! Look forward to doing more business with you!!

Worked Great

Distribution blower fit great, easy I stall and surprisingly quiet compared to our original. The bigger issue was that dealing with stove and grill parts for less was nothing short of great. Fast shipping, worked hard to clear up a minor issue. I’d deal with this store again as their customer service was top notch


Ask a Question
  • I note that you offer an NBK motor at $149.99 replacing harmon part #3-21-47120. What is price for the motor only shown in SKU: AMP20063?? This second motor offer higher RPM and amp rating almost double of the $149.99 motor.

    AMP20063 is $189.00, Blower Complete and 12189M-AMP is $149.00. Complete comes with a housing (which cannot be used because the existing housing is welded into the stove cavity) and comes with a blower wheel. Differences between the OEM and the NBK replacement are, the NBK is a sealed bearing and is capacitor start and driven. The OEM is a simple induction motor without sealed bearings. The OEM is also a variable speed motor but only the high-speed poles are used. If there are confusing specs with the Aftermarket offering that's our fault, the AMP motors are the same.
