Supco PRO 41 relay/overload combination. Where do blue wire and black wire connect?

Was the orange wire on a switched live on the old compressor connections? It may come on when the compressor goes off in that case. If not, recheck the schematic for the other end of the heater. If it has a neutral, join the orange to the live feed to the supco. If it has a live, leave the orange on the neutral of the supco.

while i loath those RO41 because your compressor will be dead SOON. The 2 black wires connect to the wires were connected to the wiring on FACTORY RELAY AND OVERLOAD WHICH WAS ORIGINALLY CONNECTED TO WHERE THE RED/WHITE/AND BLACK WIRES WITH THE TERMINALS NOW ARE.

my advice though is throw that thing in the trash and get factory OEM relay and overload

The two pieces are Relay and Overload.

If you are using a supco relay/overload combination that has three wires with terminals and two wires with stripped ends the wiring is as such.

Red-Run Terminal, White-Start Terminal, Black-Common Terminal (Overload was wired to this)

Stripped wires are connected to line cord along with condenser fan wires.

you can replace the relay with a 3 in 1 made by supco. i generally just use a supco 0410.

it is a start relay, overload, and start capacitor all in one. works great for residential systems.

You need to replace the overload/relay , plugged onto the side of the compressor , with 2 or 3 wires going to it . When you hit the compressor , the jolt , reset the overload .

Hi, If the 3 posts are top center and bottom right left, the black wire goes top the top center post. The red wire will go to the bottom right and the white goes to bottom left.
If the posts are bottom center and top right left, the black goes on bottom center and the red goes top left. The white goes top right.
If you do not see a capacitor, disregaurd the wires in the 3-1
I hope this helps you. Please let me know if I can assist you further.

hi thanks for the question . i would replace the relay and the cap then your sure your good to go. thanks te appliance doc rate me please

you can replace with an supco 3 n 1 for 1/3 1/4 (if run capacitor is used)

or use the combination relay/overload for 1/4 1/3(if there's no run capacitor)

if you need any additional help please e-mail @ [email protected]

check the relay/overload that "gurgling" could be a compressor trying to start.

you can replace the old relay/overload with a supco combination relay/overload

ok check if fans go on

you probably have an defective compressor relay/overload

you can buy an replacement at an appliance store.

supco make them just ask for an relay overload combination for 1/4 1/3 hp anyone with some electric knowledge can help install it if it dosent start up, well bad compressor hope that this helps
