My furnace is approximately 20+ years old and i need to replace the blower motor. however the replacement has six wires and the existing has 5.
Here's the existing motor's wiring diagram:
I understand the brown wires will connect to the capacitor, and the red, black, and blue wires controls speed. What I do know is what the white connects to (it’s the wiring between the capacitor and the speed controls). There is a green wire for grounding.
