Review: 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!
Review: Perfect fit - Works and perfect fit for my stove great replacement for older model.

## Questions & Answers

**Q: does the motor come with the mounting bracket and paddle fan as shown in the picture?**
A: no it does not. Usually the all in one combo set is not compatible. You could purchase separately the fan and bracket for cheap

**Q: Will this motor fit Envirofire EF3 ?**
A: Sorry, I do not know. I can say that the blower motor as viewed on line for your Envirofire  EF3 looks to be different than the Harmon Combustion Fan that I purchased. My fan has only three bolts to secure it. Caution also  in selecting the correct fan blade. They come in both single and double paddles.

**Q: “It 100% fits an advance with a 1999 build date,Chain driven?”**
A: Not sure , but I don’t think so , I have a Harmon Accentra 52i  with direct shaft drive.

**Q: Will this fit the free standing accentra 2 model**
A: It fit my freestanding p61

Works and perfect fit for my stove great replacement for older model.

### ⭐⭐⭐⭐⭐ Great quiet motor
*by B***6 on November 28, 2025*

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
