1018775R Nordyne Combustion Motor CCWLE PSC

Description

The 1018775R is an OEM combustion (inducer) motor used in Nordyne / Coleman gas furnaces to drive the draft inducer blower. It features a permanent split-capacitor (PSC) design delivering 1/23 HP with a two-pole, two-speed winding and rotates counterclockwise when viewed from the lead end (CCWLE). The motor runs on 120 VAC single-phase power and ships as the bare motor—an appropriate run capacitor must be provided separately. Total unit weight is 5.43 lb, and it drops straight into the factory mounting bracket without modification.

Compatibility

Replaces original part number 1018775 and fits any Nordyne or Coleman gas furnace calling for a CCWLE PSC combustion motor. Common applications include:

• M-series gas furnaces (M4, M6, M7 family)

• Challenger and Intertherm packaged units with CCWLE PSC draft motors

Always confirm rotation, shaft length, mounting bracket style, and electrical requirements against the furnace nameplate before ordering.

Installation & Service Tips

• Power Down and Discharge Capacitor Always isolate the electrical supply and fully discharge any existing run capacitor before removing the old motor.

• Confirm Rotation & Shaft Orientation With the motor lead end facing you, verify a counterclockwise rotation to match the inducer housing design.

• Specify Run Capacitor Use the OEM-specified microfarad rating (typically 5–10 µF at 120 VAC). Incorrect capacitance can cause reduced airflow or increased amp draw.

• Secure Mounting Reinstall using the factory bracket, gaskets, and fasteners. Ensure the motor shaft aligns perfectly with the blower wheel to prevent vibration.

• Commissioning After power-up, measure motor current draw and listen for smooth operation. Verify proper condensate and flue-gas evacuation.
