OK.....ever have one of those "I am such an Idiot" moments? I had my most recent one last night. After almost a month of delays, by replacement thermostat arrived. That is a long time to have ice chests in the kitchen.
So as I am removing the original thermostat I snip the power input wire (the one that is spliced to the power cord at the factory) to get the unit out. I remove the thermostat, roll it over, open it up to look inside. Looks really good actually. The contact points are a little black, but not bad. It looked good enough I got out my ohmmeter to double check. If you remember, earlier troubleshooting showed the thermostat was always in an "open" state. This time it checked fine. Open...short...open...short...every time I turned the knob.
That's when I realized it........since one of the wires going to the thermostat is spliced to the power cord, and does not stop/start at a relay terminal, my previous continuity check included the power cord. Now that the cord had been snipped off, the continuity of the thermostat checked fine.
A double check of the now snipped power cord showed one wire to have an "open". Crap....what an idiot. So tonight I will get some new cording, gently file the contact points (unless you think that is a bad idea), and put the original thermostat back into place. I will keep the new one as a spare.
Pay heed all....learn from my dumb mistake. Fortunately my wife is very forgiving..........the ice chests have been a real PITA.

. On a positive note, you get to keep the original control.
