Do you know your TSD from your PTC? They look the same on the outside, but are very different on the inside and fail in opposite ways. I’m talking refrigerator compressor start devices in this video odyssey. Start watching, and less than 10 minutes later you’ll know these bad boys inside and out and be able to determine with confidence which one you’re dealing with in the field. BOOM.

Excellant video Samurai!
Muched need info, probably lots of techs out there that don't know this info.
The clamp on AMP meter is another good tool to know the difference between a failed PTC, (usually lower 7-9 amps tell it kicks the overload), and a failed TSD, (usually 12-15 amps until the overload trips). Also another thing you will sometimes notice with a failed TSD is the freezer will be slightly cold, (not cold enough for even refrig temps), the continuous running of the compressor for those 10 second burst every couple of minutes does do a slight amount of cooling, but not much. Unlike with a PTC start device failure the compressor never turns over so it pretty much gets to totally warm temps in both compartments.

Or, on the other hand.....
Troubleshooting the appliance's complex electro-mechanical systems is the methodology in which one must, by using analyitical techniques and the process of elimination, determine the cause or causes of a specific failure. Rarely does this cause of a failure directly present itself for you to see.
To be better equipped to troubleshoot, you will need:
1.) To follow this: Safety first and foremost. Trust your instincts.
2.) Basic hand tools.
3.) A decent DVOM meter. Buy one. Borrow one. You need one.
4.) Last, but certainty not least, common sense. Most of us have it. Slow down and use it.
Now, let's have some fun!
Hope is the power that gives a person the confidence to step out and try.
Success is the maximum utilization of the ability you have.
It always seems impossible until it's done.
