OEM replacement outdoor blower wheel for Coleman Mach 8332, 8433, 8632, and 6701–6723 Series rooftop air conditioners. 7" diameter, clockwise rotation, 0.46" bore — plastic construction rated for outdoor and marine environments.
The 1472-1091 is the OEM replacement outdoor blower wheel for Coleman Mach 8332, 8433, 8632, and 6700 Series (6701–6723) rooftop air conditioners. Also known as a squirrel cage impeller, this is the outdoor-side blower wheel — the component responsible for drawing ambient air across the condenser coil to reject heat from the refrigerant circuit. It mounts directly to the dual-shaft fan motor that drives both the indoor and outdoor air-moving assemblies on these units.
The wheel is constructed of durable plastic and is rated for outdoor and marine environments. It measures 7" in diameter by 2-3/4" deep and mounts via a 0.46" bore. Rotation is clockwise — the correct rotation direction is essential for proper airflow direction through the condenser section.
Signs of a failing or damaged blower wheel include unusual vibration or noise from the unit, reduced cooling performance, or visible cracking and deformation of the wheel body. Because this wheel is exposed to outdoor conditions, UV degradation and physical impact are common failure causes on older units.
Squirrel cage impeller for the outdoor condenser air circuit — distinct from the indoor evaporator blower wheel on the same units
7-inch diameter, 2-3/4-inch depth — OEM dimensions for a direct-fit replacement on 8332, 8433, 8632, and 6700 Series models
Clockwise rotation — must match the original; installing in the wrong orientation reverses condenser airflow direction
Plastic construction rated for outdoor and marine environments — built to withstand UV exposure and weather conditions
The 1472-1091 is the outdoor condenser blower wheel only. The dual-shaft fan motor on these units also drives a separate indoor evaporator blower wheel. If the indoor side requires replacement, that is a different part. Identify which side of the unit the failed wheel is on before ordering.
Disconnect and lock out all power before beginning replacement. Note the bore orientation and any set screw or clamp position on the original wheel before removal. Verify the 0.46" bore aligns with the motor shaft profile. Seat the wheel fully onto the shaft, secure per the original fastener configuration, and confirm the wheel spins freely without contacting the housing before restoring power.
The OEM Coleman Mach 1472-1091 carries a 90-day limited manufacturer's warranty. Some aftermarket and third-party replacement blower wheels may carry longer warranty terms under their own policies, but those are not the OEM part covered by this listing.
