Welcome to JustAnswer my name is Mark.

Thank you for your question, and the amount of detail you provided. This amount of detail is what enables a thorough answer for yourself.

What you are experiencing is a PCM that is failing. temperature changes, be it cold or hot, cause the pc board to flex in different directions. If there is a flaw in the solder joints on the board, then the circuits can open under hot or cold temps.

The cure for this is a replacement PCM.

I hope that helps to answer your question, but if you need anything further please reply back to me. Thanks!
