Well the tech came and went. The coils were real dirty again and the thermal cutoff was packed in dirt. The refrigerator came on and started to cool and cycled off quickly. Suggested I wait a few hours and start it up again, I may get "lucky" and the packed dirt was the culprit causing the compressor to get too hot and shut off (the thermal cutoff is good). If not, the compressor would need to be replaced and he balked immediately at the complexity of the project. So most likely I'm back to square one.
