How do I wire my new Rheem Condenser Fan Motor 51-23055-11?

Rheem is the flagship line of several brands of air conditioners that all come from the same factory. Ruud, Weather King, and Corsiare all also come from the same factory and use the same parts/part #s.

There are many older condenser fan motors out there that have been on the market for a long time and Rheem no longer wants to manufacture and stock all of these different motors. Rather than simply discontinue these motors, Rheem has made the 51-23055-11 motor to replace all of them, regardless of slightly variances between the motors. This motor is reversible and can be wired to replace motors that use 3 wires as well as motors that use 4 wires (the 51-23055-11 has 5 wires itself). Occasionally, someone who has purchased this motor from us has a question regarding the wiring. Below is the information you need to wire this motor into your unit.

Please see which of these options applies to your situation and use the wiring for that application.

1.) If you have a three wire motor and a plain air conditioner (not a heat pump). The black wire will go to the top of the main contactor (to the opposite side of the contactor from the wire (usually orange, with Rheem) that connects the top of the contactor to the "c" terminal on the capacitor. The orange wire on the motor goes to the "c" terminal on the capacitor. The purple wire will connect to the capacitor terminal "Fan". The remaining wires (brown and yellow) and simply connected to each other and then taped up and moved out of the way. If you need to reverse the rotation of the motor after installing it, swap the brown and purple wires.

2.) If you have a three wire motor and a control board in your unit (usually a heat pump). See the wiring description for option #1. The only difference is that the black wire goes to the "fan" terminal on the control board as opposed to the contactor.

3.) If you have a four wire motor and a plain air conditioner (not a heat pump). The four wire motors have a seperate capacitor just for them. In this case, you will take the black wire and attach it to one side of the top of the main contactor. The Orange and Purple wires will be tied together and connected to the opposite side of the top of the main contactor. The brown and yellow wires will go to the capacitor (it does not matter which side of the capacitor- with a four wire motor the capacitor will only have 2 sets of terminals on top of it and these two wires -brown and yellow- can go to either set of terminals). To reverse the rotation of the motor, swap the brown and purple wires.

4.) If you have a four wire motor and control board in your unit (usually a heat pump). See the wiring description for option #3. The only difference is that the black wire will go to the "fan" terminal on the control board. Make sure that your orange/purple wires connect to the same side of the main contactor that has a wire connecting directly to the compressor capacitor.
