Draft Inducer Motor Assembly
The inducer motor is the first component to move in the ignition sequence. Squealing occurs when the internal bearings lose lubrication or seize, creating high-pitched friction specifically during the initial ramp-up. Replacing the full assembly is the standard industry fix as the motors are typically sealed.

Indoor Blower Motor
If the squeal occurs 30-90 seconds after the thermostat clicks, the main blower motor is the culprit. Worn bearings or a failing capacitor (in PSC models) cause the motor to struggle and squeal while attempting to reach operational RPM.

Blower Wheel
Research indicates Goodman blower wheels can suffer from blades separating from the center hub under high static pressure. This structural failure causes the wheel to become unbalanced and rub against the housing, creating a high-pitched metallic screeching sound during startup.
