3 Wire Vs 4 Wire Condenser Fan Motor Wiring Yo The differences between 3 wire and 4 wire configurations are especially important when you're replacing an oem condenser fan motor with an aftermarket condenser fan motor. the main difference between the two wiring configurations lies in the utilization of the brown and white wire. the 4 wire configuration uses the brown wire as the capacitor. 3 wire and 4 wire condensing fan motor.
3 Or 4 Wire Condenser Fan Motor Wiring вђ Johnstone Supply How to wire condenser fan motors properly in 3 wire & 4. Bryan explains the difference between 3 wire and 4 wire condenser fan motor wiring configurations. the differences between 3 wire and 4 wire configurations a. In this case, the two power wires—l1 and l2—are white and black and will mount to the t1 and t2 terminals of the contactor. these wires supply high voltage to the condenser fan motor once the contactor closes. the orange and yellow wires are the fan rotational wires. switching these wires will change the rotational spin of the fan. So here are 2 diagrams of a condenser fan motor wired first in a 4 wire configuration and next as a 3 wire configuration. as you will see, the "white" wire and the "brown white" wire are connected internally and are really the same input into the main winding and capacitor. note: please don't be confused by oem wire colors.
