Payne outdoor unit runs but indoor blower does not; coil may freeze and little or no air comes from vents.

Safety: Turn off power to the furnace/air handler before opening the blower compartment.

• 1. Thermostat fan test: Set the thermostat fan to ON. If the blower does not run, the issue is likely with the blower or its controls.
• 2. Inspect blower wheel: Remove the blower access panel. Check that the blower wheel is not jammed by debris and spins freely by hand.
• 3. Check capacitor (PSC motors): Locate the blower capacitor. If it is swollen or leaking, it should be replaced with the same microfarad and voltage rating.
• 4. Wiring and board: Ensure the motor harness is firmly plugged into the control board and that no wires are burned or loose.
• 5. Motor replacement: If the motor hums but will not start, or is completely dead with proper voltage present, it likely needs replacement by a technician who can match the correct Payne blower motor and balance the wheel.
