When your pellet stove stops circulating warm air, the convection blower motor is one of the first components to suspect. This is the genuine St. Croix replacement convection blower motor (part number 80P20003-R, also sold under NBK Parts number 20144) engineered to restore proper room-air circulation to a wide range of St. Croix pellet stove models. Drop-in fitment, correct electrical ratings, and Class B insulation mean you restore your stove to factory performance without guesswork.
The convection blower motor is the heart of your pellet stove's room-heating system. Unlike the combustion blower -- which feeds air to the burn pot -- the convection blower draws cool room air across the heat exchanger and pushes warm air out into your living space. A failing convection motor means your stove may be burning fuel efficiently while delivering little usable heat to the room. Replacing it with the correct OEM part is a straightforward DIY repair that restores full heating capacity.
Part 80P20003-R is rated at 115 volts, 60 Hz, and draws 1.39 amps at 2300 RPM. The Class B insulation rating means the motor windings are built to handle sustained operating temperatures up to 130 deg C (266 deg F) -- appropriate for the thermal environment inside a pellet stove cabinet. At approximately 8 lbs, this is a robust, full-size motor assembly.
Genuine St. Croix part 80P20003-R ensures correct fit, voltage rating, and shaft dimensions for listed models -- no modification required.
Confirmed fitment across 12 St. Croix pellet stove models including Prescott EXL/EXP, Hastings, Lancaster, Auburn, and the 2012 SCF-Revolution.
Motor windings rated for sustained temperatures up to 130 deg C, matching the demanding thermal environment inside a pellet stove blower compartment.
2300 RPM output matched to the original fan blade and housing geometry -- restores factory air delivery without over- or under-speeding the blower wheel.
This motor is designed as a like-for-like swap for the original convection blower in all listed St. Croix models. If your existing motor carries part number 80P20003-R or is referenced as NBK 20144, this is the correct replacement unit.
This convection blower motor fits the following St. Croix pellet stove models:
St. Croix pellet stove models have been manufactured over multiple production years and some models received mid-run component changes. Confirm your stove's existing blower motor carries part number 80P20003-R, or cross-reference using NBK Parts number 20144, before ordering. Your stove's service tag is typically located on the back panel or inside the rear access door.
Knowing when to replace the convection motor saves you from misdiagnosing other stove components. Common failure signs include:
When installing a replacement convection motor, inspect the blower wheel (squirrel cage) for dust and debris buildup. A clogged wheel forces the new motor to work harder and shortens its service life. Clean the wheel thoroughly with compressed air or a stiff brush before reassembly. Also verify the motor mounting screws are snug -- vibration from a loose mount accelerates bearing wear.
Replacing the convection blower motor on most St. Croix stoves is a DIY-accessible repair for owners comfortable with basic electrical disconnects and fastener removal. General steps include:
Always unplug the stove from its 115V AC outlet and wait for the unit to cool before servicing any internal components. The convection blower motor operates on 115V household current -- live-circuit work risks electric shock. If you are not comfortable working with AC-powered appliances, arrange for a qualified pellet stove service technician to perform the replacement.
