This refrigerator stopped cooling all of a sudden the other day. Freezer was totally defrosted and refrigerator area not cooling. Air is blowing in both compartments. I took back panel off and found;

1) Fan is running
2) Compressor is not running
3) Overload relay/run capacitor clicks, then compressor starts to make
a little humming noise and then relay/run capacitor clicks again and
then nothing from compressor.

Remove the start device from the compressor side and make a note of the wiring to it, then order a new one AP4013414

The part that was sent has different wire connections than what the original had. Here are the part numbers from the two:

Original: 5SP04T419PFM
01 H03R

Replacement: 5SP14M419PF
29 Z11R

The original has two male terminals on the back that are the same size and get connected by one snap on terminal from the wire harness.
The replacement has two different sized male terminals that are in different locations and would require splitting the original wire harness and adding new sized connectors before being able to make the connections.
Is this what I need to do or is there another switch that has the correct terminals on it for my application?

If the original start device is not identical to the new one, you will have problems installing it. If so, call the parts site and explain the problem.

I called them as soon as I noticed the parts were different and was told that there were different manufacturers for that refrigerator and I would have to go to the website for installation assistance. Isn't there a switch made that will fit in the same manner as the original one?

If the new start device is a large box, it has three round pins to plug it in the compressor and four terminals on the other end. Two terminals for the run capacitor and two for the compressor, one going to the internal overload klixon and the other to the internal ptc device. If so, just plug in the run capacitor and change the two wires from the fridg plug to mating spade terminals to plug in the mating device terminals, polarity is not important.

Just to make sure. There are the two wires that plug into the switch. One is blue and the other is white. On the switch there are two spades. One is wider than the other. Does it matter which wire goes to which spade?

No it does not matter. You will need to get the correct crimp on spade terminals for them.
