🛠️ HVAC Depot Pro Tip: The ECM Communication Check

Before replacing an ECM motor, always verify that the motor is actually getting both its high-voltage power and the low-voltage communication signal from the control board. If the fan isn't spinning but the motor is warm, check the harness for secure connections and ensure the fan blade is balanced; an unbalanced blade can cause premature bearing failure on these high-precision motors.
