Coldspot Refrigerator wiring
Wow, you are very talented at creating graphics. I will try those things. I could also buy a new relay if necessary. I will be honest I am used to working with electricity to the extent of changing outlets and switches, wiring things with a simple wiring structure, but I have never used any kind of meter. Now I do have a meter that I bought to check for voltage, but have not even take it out of the package. If this is the type of meter you are talking, I can give it a try. When you talk about measuring the resistance, I'm assuming you are just referring to the whatever reading I get on each wire/pole.You may have have disconnected the relay inside the box. Between pulling the wires off and disconnecting the relay inside, the hot wire relay may be damaged but it's not a problem. We will find out as we go. Follow each one of these steps exactly as I have them. This isn't hard to do so take your time and write down any measurements. If you have any questions as we go just ask, don't guess.
Turn the cold control to the off position and remove the light bulb inside the refrigerator.
Remove the three wires on the relay going to the compressor and mark them as I've indicated in the diagram

Remove the other two wires on the relay coming from the cabinet

At this point there should be no wires connected to the hot wire relay. Set your meter to check ohms on the lowest scale, R x 1. On the relay, measure the resistance between the two screws where compressor wire #3 and #2 were connected. Write it down.

Measure the resistance on the relay between A-B, C-B, D-B and A-C. Write them down and set the relay off to the side for now.

Leave the meter on the same ohms scale and measure from each of the 3 wires coming from the cabinet to a ground or cabinet screw. Your meter should indicate 1 or open for all three wires. Anything other than 1 or open STOP and let me know. If all three measurements are 1 or open go to step 7
I labeled the wires coming from the cabinet 1=white 2=black and 3= the wire with the red tape around it. Connect your meter to #1-white wire and #3- red tape. Your meter should indicate 1 or open. Turn the cold control to the on position. Your meter should indicate 0 or closed.

Turn the cold control to the OFF position and replace the light bulb in the light socket. Make sure it is a good working light bulb. Connect your meter to wires #1 and #2 from cabinet. Meter should indicate 1 or open. Push the door switch in. Meter should indicate 0 or a .02 or a .01 or 0.0

Don't worry if the measurements are not exactly the same. I'm only checking where the wires are going. Post back your results.
