When your Classic Bay 1200 stops circulating warm air efficiently, a worn convection blower motor is usually the cause. The QuadraFire 812-3370 is the direct OEM replacement -- a 2-speed, 115V motor engineered specifically for this stove, with the correct RPM ratings, amperage draw, and wiring connectors to drop in without modification.
The convection blower motor is responsible for drawing room air across the heat exchanger and pushing warm air out into your living space. Unlike the combustion blower (which manages exhaust), the convection blower is what you feel when you hold your hand near the stove's air outlets. A failing motor shows up as reduced heat output, unusual noise, or a motor that hums but won't spin.
This 812-3370 motor is built to Class B insulation standards, rated for continuous duty at 115V/60Hz, and ships with three 1/4" male spade wiring connectors pre-attached -- matching the factory harness in the Classic Bay 1200 so no splicing or adapter harnesses are needed.
Runs at 2300 RPM (high) or 1420 RPM (low), letting the stove's control board match airflow to heat demand for quieter low-burn operation.
Designed exclusively for the QuadraFire Classic Bay 1200. Correct mounting footprint, shaft size, and wiring connectors -- no modifications required.
Rated for sustained high-temperature environments typical of pellet stove interiors, providing longer service life versus generic motor substitutes.
Includes three 1/4" male spade connectors matching the factory harness. No wire splicing, no terminal crimping -- connect and secure.
Catching a failing motor early prevents secondary issues like overheating. Common signs in the Classic Bay 1200 include:
Replacing the convection blower motor on the Classic Bay 1200 is a straightforward service job for a mechanically comfortable stove owner. The motor mounts inside the stove cabinet and connects to the blower wheel via a set-screw hub. General process:
