Just got back from a job that's bugging me. I have a 2 Carrier 5 ton
condensers (approx 8 years old) with blown thermistors. I think they
may be on the same electrical circuit (which makes no sense - but they
told me they had one tripped double pole breaker - I can't get into
the mech room until tomorrow morn), I had no power before the
disconnects of either one.
ANy ideas why the thermistor would blow? They are wired into the
start circuit with a start capacitor (no start relay)... Do they just
get old and die??
