3 Wire Vs 4 Wire Condenser Fan Motor Wiring Youtube Since most oem motors only have 3 wires and most replacement condenser fan motors have 4 wires, this creates a little confusion. the common lead (white) and the brown with the white tracer contractor leads are wired into the same circuit, so the brown with the white tracer can be cut off and insulated with a wire nut and electrical tape — you don’t need it. 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.
3 Or 4 Wire Condenser Fan Motor Wiring вђ Johnstone Supply Cap off brown white (unused). now, for your 4 wire method: white wire from the condenser fan motor to one side of power on the contactor (t1). black wire from the condenser fan motor to the other side of power on the contactor (t2). brown wire from the condenser fan motor to the capacitor. again, this is ac power and not a dual capacitor, so. 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. 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.

To wire a condenser fan motor using the 3 wire method, follow these step by step instructions: turn off the power to the hvac system at the circuit breaker. locate the condenser fan motor and identify the three wires: white, black, and brown. connect the white wire to one side of power on the contactor. This is how to wire a 3 wire and 4 wire condenser fan motor into the outdoor unit. i go over how to eliminate the use of a second run capacitor when replacin.
