I’m replacing the start relay for my frig but the original part is no longer available. It is a two wire unit that has the overload, relay and capacitor. The replacement is two seperate pieces. The relay and the overload. Looks easy enough to plug in the compressor, but since I only have two wires (black and blue) not sure how to wire it up. I’ve watched Youtube videos, and in each case, there are 3 wires running to the old start relay/overload unit. (blue, black and red)
How am I to hook up the new overload and relay?
