Completely transformed my pellet stove experience!
I bought my first pellet stove, a used Harman P43, last winter. I couldn’t be happier with it, however starting it for the first time this season I could tell something wasn’t right. It was making a metallic grinding sound. After some research I came to the conclusion it was the fan and bought this replacement. I am blown away, It’s so quite I actually thought I might have installed it wrong. Seriously I was just expecting to get it back to the sound level it was at last winter. But this far exceeded my expectations. It’s no louder than a ceiling fan! Additional insight: Delivery was quick and it came packaged nicely. Installation was extremely easy once I got the old fan out. A helpful tip if you are replacing the original fan, the set screw holding the old blade on the inside will most likely strip. Save yourself the headache and cut the shaft with a sawzall from the back of the stove. If I had done that from the start installation would have been 10 minutes. Build quality seems to be excellent. However I just installed it so I can’t speak on longevity quite yet. Value is 10/10. Worth every penny! Wire length is more than enough and the even include the crimp connector so all you have to do is cut the wire off the old blower motor, crimp the connector onto the wires and plug them in, couldn’t be easier!

Great quiet motor
What a great motor, ten times better than the noisy motor that came with the unit. FYi…do not buy any motor that comes without a new fan blade because its very common to have to cut the fan and shaft with a grinder to remove the old motor. I know…I didn’t design it

Works
Easy to hook up and it works. The gasket that came with it was junk, ripped when I took it out of package but other than that good piece

Works good. It looks different than the motor that came out of my stove
I bought this for my older Harman Advance pellet stove. It doesn’t look the same so I was reluctant but the part number matched. So I bought it. It fits and works perfect. It’s nice and quiet again. I added a picture of the old motor in case anyone has the same concerns as I did.

Worked perfect on my Harman P43 Pellet Stove
Bought this to replace the original combustion motor on my 10 year old Harman P43 Pellet Stove after the bearings went bad. This new aftermarket motor has good reviews so I figured, for less than half the price of an OEM motor, I'd give it a try. So far I'm very pleased. It was easy to install, even though I had to clip the connectors off and splice it directly into the wires coming from the stove. It even came with the Fan Blade Impeller that attaches to the motor's shaft inside the ash pot compartment. The best part is it's super quiet. The only question is how long will it last? The original motor lasted 10 years of constant 24/7, seven days a week, use heating my NY home during the winter months. I'll settle for half that time.

Works but need to jury rig it
I have a p43 harman and this had way too short of wires, so I had to make an extension to plug into the stoves harness. The locking screw for the fan isn't the same size as the OEM part, it's metric instead, and the nuts that mount it to the studs are also a very different size. Comes with a metal plate and gasket, which doesn't work on my stove so I had to just re use the old ones, including the old nuts so make sure you don't lose them. I give it 3 stars because it does work and after listening to a loud motor for months and finally having silence is nice, but make sure you have extra wire, terminal ends, and patience
