A direct drop-in replacement for the exhaust inducer draft motor assembly on a wide range of Carrier home furnaces. The NBK Parts 20832 matches the original electrical specifications -- 208/230V, 3450 RPM, 0.47A at 60Hz -- so there is no rewiring or adapter work required. It cross-references Packard 66815, Carrier 1171314, HC30GB232, and several other common OEM and aftermarket part numbers, making it a go-to replacement for HVAC technicians and DIY homeowners alike.
A failed exhaust inducer motor is one of the most common reasons a Carrier furnace locks out on a call for heat. The inducer pulls combustion gases out of the heat exchanger before and during a heating cycle -- when it fails or runs slow, the pressure switch won't close and the burners won't light. Replacing the motor assembly is a straightforward fix that restores normal operation without replacing the entire blower housing.
NBK Parts engineered the 20832 as a functional equivalent to the original Carrier assembly, using matched electrical specs and compatible mounting geometry so the swap goes in the same holes with the same wiring connector arrangement.
Replaces Carrier 1171314, 48SS400380, 48SS400606, 50DK406181, 50DK406815, HC30GB232, Packard 66815, Universal JF1H092N, and ICP 1171314 -- one part covers multiple OEM and aftermarket numbers.
Rated 208/230V at 60Hz with a 0.47A draw and 3450 RPM shaft speed -- identical to the original Carrier specification, no voltage adapters or wiring changes needed.
Mounting geometry and flange design mirror the OEM assembly, allowing installation without drilling new holes or modifying the existing inducer housing or pressure switch tubing.
Backed by a limited 1-year manufacturer warranty from NBK Parts, covering defects in materials and workmanship from the date of installation.
The exhaust inducer (also called the draft inducer or induced-draft motor) sits upstream of the heat exchanger and creates negative pressure to draw combustion gases through the burners and out the flue. On most Carrier single-stage and two-stage gas furnaces, the inducer runs for a short pre-purge cycle before ignition and continues running through the entire heating call.
The pressure switch monitors the airflow the inducer creates. If the motor is worn, bearings are noisy, or the motor has failed outright, the furnace will fault -- typically a pressure switch error code -- before the burners ever fire. Replacing the motor assembly (motor, wheel, and housing as a unit) is almost always faster and more reliable than sourcing just the motor and attempting to press a new one onto an old wheel.
The 20832 is built to replace the following OEM and equivalent part numbers. Verify your existing part number against the label on the motor or in your furnace's service manual before ordering.
Carrier and ICP (International Comfort Products) share a common platform for many gas furnace chassis, so this assembly may apply to ICP, Heil, Tempstar, and Comfortmaker models that reference the same part numbers -- confirm by matching the part number on the existing motor tag.
This is a moderate-difficulty DIY repair for a homeowner comfortable working inside a gas furnace cabinet. The general process is:
