So, the lesson is before you buy a new thermostat check your system pressure
to make sure there is optimal refrigerant in it.

You can buy an IR gun type thermometer for a very reasonable price at
NAPA which is useful for checking all kinds of things. To properly
check refrigerant level you really need a full set of gauges to see
what the high pressure side is doing while you observe the sight glass
on start up.
