Here it is... I just rewired a C27 with a new modern compressor harness. & repaired the sold out switch mechnism.

Yeah..220, 221 whatever it takes.

I need the diagram for the original Fridgeaire Compressor .  Been working with a few resources on a few options .  The compressor is a LOX 1212 Meter Miser like they used in a domestic fridge .

My original thought was to buy a 3-1 relay and wire C, S, R and use a newer style 4 lead compressor but it sounds like these older units don’t allow based on the relay and t stat being tied in together . Perhaps it I also change the t stat ?
 
The other option is to make my old wiring harness which I don’t relish doing .  I have a poor sketch of what I think might work... I’ll resize and attract shortly .  

The only thing mid picture is a hot wire for power strip which I could get a hot from either my fan or directly out of the relay box with an extra lead.

How did you tie in the on board relay did you use 3 and 1?

I eliminated the original T-stat, the old start-run potential relay assy. & wired in a standard replacement vending machine wiring harness and  a 3-in-1, it simplified things quite a bit.

That was my original idea but i was told since the original compressor and t stat are tied together that it wouldn’t work .  
By eliminating the old t stat I assume you replaced with a new one ?  Contact or Non - Contact?  I was told by the suppliers they don’t make the evap fan motor luckily mine works .

Did you just use ring terminals for the C, S, R?

Yes, I used a new Ranco beverage cooler/non-contact type,  also I used ring terminals on the compressor leads.  The evaporator fan is a joy to change as you have to remove the drum ‘s guts to get at it, but I have succeeded in adapting a standard unit-bearing motor in the past, fortunately,  this machine didn’t need it replaced ( plus it was an “economy” repair anyway and not a full on restoration)  getting the compressor replaced is also a chore as the whole chassis/body  must be lifted up & off in order to remove and replace it.

One more thing, use a properly sized 3-in1  (1/5Hp in this application) if you go too big, say 1/4-1/3 HP, you run a very good chance of damaging the start winding on the compressor, & then you’ll be crying.

I removed 2 of them this week.  I live to tell the story. I bought the Supco RC810 - 1/12-1/5.  Did you use a 3 lead so you have a hot wire to feed the terminal strip ?

Nope, just the two-lead model, the replacement compressor harness has an accessory connector that supplies line voltage ( not switched) it’s just not shown in my state of the art drawing...   tounge  I just tapped onto that & wired it into the upper terminal strip to supply line voltage to the vending & sold-out circuit.

Yep that’s the pileup I remember!    Oo    Jeeze, they always look so cute & innocent on the surface, ( just like kids  laugh  ).
