CWSE; Bearing Type: Ball; Safety Switch: Auto Top; Wiring: Three Wires with Molex Plug, Includes 2 Prong Plug Adapter. Two Speeds – Designed to replace bryant/carrier hc21ze122a inducer motor, this unit operates at two speeds, drawing only 1.32/0.39amps while delivering 3000 RPM. With a reliable 115 volts supply, it ensures optimal air circulation, making it a must-have for maintaining a comfortable indoor environment while saving on energy costs. Inducer Motor Function: This carrier 326628-763 draft inducer motor assembly is designed to expel the exhaust gas from the furnace. Older inefficient furnaces allowed the flue gas to escape the unit with virtually no resistance. Newer high efficient furnace heat exchangers are so restrictive that the flue gases cannot exit the furnace though natural draft. Therefore, the inducer is required to pull the flue gases through the heat exchanger. The inducer motor is usually the first thing that starts up when your furnace calls for heat.
