Kitchenaid refrigerator KSRI25FNWH00 won’t cool

[William S]

Freezer and fridge stopped cooling.   Compressor clicks on, then 5 seconds later clicks off.

^{I would test the starter device you have there possibly the run capacitor if there is one seems to be the issue to me  you could test the windings on the compressor the triangle probes whichever is top or bottom should be common the other two are run or start}

The run capacitor that is attached to the start pak won't be the problem, (unless it is shorted).

This unit uses the TCD start device - not the standard PTC start device.

The TCD start paks are electronically controlled with a circuit board inside the device and work on a time delay instead of like the PTC disk shutting off the start windings.

The most common way a TCD start device fails is that it never removes the start windings from the circuit, so it will run the compressor for 10 to 20 seconds then shut off on the overload.  When the overload resets, (5 to 10 minutes), it will try to start again and keep repeating this process.

If the TCD start device fails in this manner you will usually notice a little cooling going on but it will never run long enough to get the temp down to anywhere near where it should be.

If you put an amp-clamp on one of the two wires going to the start device you will most likely be seeing a high amp draw, (9 to 12 amps), for the 10 to 20 seconds the compressor is running before it trips the overload.

oops, that's what I get for opening my mouth thank you @Budget Appliance Repair you school me every time!!! Some day I will get there but not today, thank you!!!!

So i likely need a tcd start device?  which seems to be tough to find.

whatever Willie says I would do that... he's not been wrong on advice to myself and many others!!! listening to me is a bad news LOL

Why do you say it's tough to find - the parts diagram may be throwing you off - they show for a different start device for a replacement compressor and the TCD start device that you need for the production compressor.

Here's the part you should be looking for - Part# WP2319792

EDITED TO ADD:  I personally don't like the TSD start devices - they are usually a lot more expense their PTC counterpart and I feel they are harder on the compressor when they fail in the manner described above, (constantly running the compressor on the start and run windings repeatedly).

There are a couple good Whirlpool kits that work on a lot of applications that most techs will normally have in stock and if one uses the same overload as the new required part I would use one of these and have them up and running without waiting for a part.

Looking at the above TSD start device, it uses the 437NFBYY overload.

This kit has two all in one PTC start relay/overload paks and also individual start relay and separate overload of two different specs.  The combo relay/overload start pak, (orange dot 2188830) in this next shown kit would be an acceptable replacement.
