Thanks, John. Good advice. I think I'll get the shop to confirm the
thermostat is working.

I usually like to explore the root cause of any issue whether it is
mechanical or otherwise. Sometimes it is too easy to think that you have
found the source of the problem only to find it occurs again because you
haven't found the root cause.
