UPDATE: New Harman Advance pellet stove, rumbling noise and auger motor noise

[Keneth Ryno]

Jabo's friend here. Jabo came up and we installed a Dayton Auger motor AC Gearmotor, Parallel Shaft, Voltage Rating 115, 1 Phase, 60/50 Hz, Nameplate RPM 4, Full Load Torque (In.-Lbs.) 175, Overhung Load (Lb.) 55, Input HP 1/60, Gear Ratio 796:1, Full Load Amps 1.2, Insulation Class B, Open Enclosure, Auto Thermal Protection, All Position Mounting, Motor Type Shaded Pole. The only difference with this motor then the Avery Gleason that was in my Accentra wood pellet stove was the fact that the shaft was turning clockwise and we needed it to turn counter clockwise. So after further review we reversed the winding of the motor so the power posts were towards the gear box and this made the shaft turn counter clockwise. Brilliant right, so it is working fine and all is well in Pellet stove land again. Once again the Motor is a Dayton 5CFL1 Shaded Pole Gearmotor and can be purchased at Grainger. Thanks for all of your input and hope this little ditty might be of help to others when it comes to replacing the auger motor.

I've had my XXV about two years now, it's a beautiful stove, works well and is solid in construction. However, the auger noise is very annoying and the "woofer" issue pops up frequently. I'm with the rest of the members when I find it difficult to understand why Harmon's engineers are not able address these issues.

At my own expense, I've ordered a new auger motor (my dealer is virtually worthless) and hoping for some relief. As per a members suggestion, I'll try the high temp grease on the old motor and see what happens...I like the idea of isolating this thing but haven't figured out an elegant way to accomplish it...yet.

I guess there's comfort in knowing I'm not the only one with these issues. One would think Harmon could (or would) correct their shortcomings and make the perfect stove...and happy customers!

Oh well...

After all, their slogan is "Built to a standard. Not a Price."

While your at it Harman (as if your listening) why not add a center detent to the on/off potentiometer. A bit of tactile feedback would be VERY helpful when trying to negotiate the "off" (or on) sweet spot. It's almost like Harmon people never use their own product...
