Needing to replace wiring on 1939 Hotpoint Refrigerator.
Cat No 320EC640, Model # (?) CE-2-B16

Would like to try keeping original parts (relay & condenser motor) if somehow can obtain a diagram of how wiring is placed within the condenser fan motor (5K51AL1).

If original parts are recommended to be replaced, what replacement parts would be close to the original.

Relay information -
CR 1057-R1
CAT MIA168
V110 CYC 50/60 HP 1/8
3.0 AMP

I need some pictures of the machine. With machines this old, numbers are not a lot of help. The wiring depends on what electrical components are being used. This is typical wiring for a machine with a condensor fan motor:

The condensor fan motor is wired the same as in my diagram. Your wiring might not look like my picture but it's the same. The first diagram shows three wire nuts. I made the original diagram to show how to go from a hot wire relay to a solid state relay. I took out the solid state relay and added the hot wire relay to more represent what you have now. The hot wire relay uses "dummy" posts for wire connections.

This is the exact same wiring circuit path without the wire nuts:

This is how you would splice in a solid state relay:

Looks simple enough. Just to clarify, I will install a start capacitor off of the compressor followed by a relay/overlap switch before connecting everything together. Do you recommend one size of the relay/overload and start capacitor over the other? Or in my case which HP switch would be better? I thank you so much for the information. Hopefully I can have it up and running this weekend!

Huh?? Sorry, not following you. Is there a start capacitor on it now?

Disregard that question, had a moment and it was late. ha

What about the wiring that goes into the fan motor. It is shot and it appears that White wire, green wire and black wire was just tied around the copper within the motor is this correct or do you suggest me replacing the fan motor. If so what motor do you recommend. Unfortunately the wires literally disintegrated as I was dissembling so I was unable to take note of how they were definitely placed.

I can't tell anything from the pictures. Does the motor work? If you need to replace it, look on the motor case for direction (CW CCW) and rpms.

My model does not have a light or door switch. I have the following wires. Also the original relay does not have letters. Just numbers 1-5 and original wires being attached at locations 1, 2, 3 and 4.

- Power cord: Black and White

- Soldered wires on bottom of compressor - Black, White & Green

-Wires coming from freezer section (runs down the back of the fridge): Black, White & Green

Wiring from fan: Black, White & Green

The relay as you know has Black, White, red and 2 black wires on opposite.

Do you happen to have a diagram that reflects my model without the door light and switch.

I can make you a new diagram if you can answer a few questions first.
Besides the cold control/thermostat, how many other electrical devices (if any) are there? What is this?:
Snapshot_6.jpg

How many wires are connected to the cold control?
Snapshot_5.jpg

Which terminal on the relay was the power cord "black" wire connected to. Where was the black wire from the fan motor connected?

Sorry I have gotten a bit overwhelmed. I do have a light bulb 🤦‍♀️, that's what happens when you get a 15 year old to look for you. The thermostat, door switch and light are ALL tied together in the top of the fridge. I have one set of wires that run down the back of the fridge, from the top that consists of a white, green and black wire. There is also a set of green, black and white wires coming from the bottom of the motor and a set coming out of the fan motor.

The black wire in the power cord was tied in with the the black wire coming from the top of the fridge, those were the only 2 in that set.

#1 on old relay had the following - white wire from fan and white wire from fan motor.

#2 on old relay had the following - Black wire from fan, black wire from motor, White wire from power cord and white wire coming from the top of fridge.

#3 on old relay had the following - green wire from motor and green wire from fan.

#4 on old relay had the following- green wire coming from top of fridge.

I really hope this helps as it has been in the family for a while. It was running all the way up to the time it was unplugged, which has also unfortunately been a while.

If you are able to do a diagram, that would be amazing. The more idiot proof it is at this point, the better.

I look forward to hearing from you soon.

white wire from fan and white wire from fan motor.......Black wire from fan, black wire from motor,..... white wire from fan and white wire from fan motor
Fan and fan motor are the same thing. The green wires are probably just ground wires. You can check it for continuity with your meter. Measure from the green wire to ground or cabinet screw. On the condensor motor measure from the green wire to the condensor motor body.

Okay. Will check tomorrow. If they end up being ground wires, should I just pull them and connect everything as in the attached diagram you sent me using just the black and white wires?

Thanks

Okay, I am not an artist and by far not an electrician. I however did create light today and made a diagram of where every wire that is located within the fridge travels to. I created it by color to hopefully make it more understandable, I am a visual type person. I did not get any action out of the compressor or fan today and electric was traveling to the screws around the inner frame of the door.

Also, I included the information from the old relay and numbered the wires according to what section they were connected to prior to everything being pulled apart.

I hope this helps.

That sounds like a short. Did you get a shock? That wouldn't surprise me. The wires insulation gets so brittle just moving the wires causes it to fall off. Some of the wires are attached to the cabinet between the outer wall and the box. If the wire casing falls off at that connection you'll get a short. Here's a trick; If you have a two wire plug, unplug it and turn the plug around.
I see three wires coming from the cold control. Are two of them connected together? What are these 2 parts I circled?

I will try flipping the plug around this evening and see what I get. I have attached additional photos that I have. It appears the copper on the left feeds in the freezer section. I will have to get a clearer photo of the item on the right as I am not quite sure what that is. There was shock if I touched a screw, otherwise it was okay.

At this point all wires have been traced and replaced in exception of the power cord and the rubber (2 section) cord that goes to the light bulb.

None of the 3 wires coming from the temp control were connected together. Two (a green and black) went to the wires going down the back of the fridge and one went to the door switch (black).

Is the green wire connected to a ground screw? What am I looking at in the second picture?

At no point have I found where a ground cable has been connected to a ground screw. The only green wires there is, is the one that comes up from the temp control, runs down the back of the fridge and connected to #4 on the old relay. Then the green wire that comes from the fan and connected to #3 on the old relay along with the green wire from the compressor.

As for the photos on the 2 items you circled, that is copper tubing that come out the side of the freezer unit and exits the top of the fridge before running down the back of the fridge.

The little silver tube comes out of the freezer unit from the left outer side, circles around the back, before going up and out the top of the fridge to that ball shaped item that is mounted to the top of the fridge.

I am sure all that, I assume, has to do with the refrigerant.

OK, so there's 3 terminals on the cold control. Can you take a pic so I can see it. I just don't want to make any mistakes when I make your diagram.
