When your Harman pellet stove or furnace stops feeding fuel, the auger motor is often the culprit. The NBK Parts 20130N is a direct-replacement auger feed motor built to the same specification as the OEM Harman part 3-20-09302 -- same 6 RPM output, same clockwise rotation, same shaft dimensions, and the same 115/120V AC input. A dedicated cooling fan is included and pre-matched to this motor, so you get everything needed for a complete drop-in swap.
The auger feed motor controls how quickly wood pellets are moved from the hopper into the burn pot. A worn or failed motor causes erratic heat output, frequent shut-downs on high-temp limit, or a fire that simply won't sustain. The NBK 20130N restores correct pellet feed rate -- keeping combustion consistent and your flue temps in the normal operating range.
This motor ships with its purpose-matched cooling fan already included. Harman auger motors in this family require active cooling to prevent overheating in the tight cabinet spaces typical of the HF60 and P-series furnaces. The included fan is sized and pre-drilled for this exact motor -- no improvising required.
6 RPM output matches the OEM spec, preserving the pellet-to-air ratio your stove was tuned to deliver.
The dedicated cooling fan ships with the motor -- no separate purchase or improvised mounting needed.
3/8" diameter x 1" long shaft matches the OEM auger coupling. No adapters or modification required.
Two female 1/4" quick-connect wire leads plug directly onto your existing harness terminals.
The 20130N is a confirmed replacement for the following Harman pellet appliances. Serial number breakpoints are noted where the motor fitment changed mid-production run:
This is a standard motor swap on Harman P-series and HF60 appliances. General procedure:
Auger motors in pellet appliances run continuously during heating cycles -- sometimes 8 to 12 hours per day through a full heating season. Common failure modes include:
