Disconnect the start capacitor
If your unit has a start capacitor is must be disconnected. Not all units have start capacitors so
first determine if your unit has one. Follow the red wire from the compressor into the electric box
(arrow 2 in Image 18). If this wire leads to a PTCR (pointed to by arrow 3 in Image 18) you have a start
capacitor that must be removed. If you do not have a start capacitor, you can continue to the next step
placing the orange wire.
First locate the start capacitor. There may be up to 3 capacitors in this design. The metal case
capacitor (pointed to in Image 18 arrow 5) is the “run capacitor”. If the unit has a start capacitor, it will
have a red and a yellow wire connected to it. If the unit has a fan capacitor, it has two brown wires
connected to it. Disconnect both red and yellow wires from the start capacitor. Follow the wires to the
other end of the wire. Disconnect and remove the wires.
Disconnect any remaining red wires from the compressor from the PTCR and remove the PTCR.
Reconnect the wires to the PTCR terminals on the connection block.
Orange wire
Install a piggyback quick connect on the ORANGE wire from EasyStart. Disconnect the red wire
from the compressor. Plug the ORANGE wire from EasyStart into the empty terminal created by
removing the red wire from the compressor. Plug the red wire from the compressor into the orange
wire’s piggy back connector end.
Black wire
Install a female blue quick connect on the BLACK wire from EasyStart. Connect it to an empty
terminal in the same group as the purple wire. (see Image 18 arrow 6). Image 18 arrow 7 points to a
barely visible extra terminal on the connection block where the black wire can be connected.
