Last night the main power switch on our furnace shorted out (possibly due to condensation, we're not sure.) That problem is fixed but now the thermostat isn't getting power and AC isn'tworking. There's power to/from main power switch on furnace, and it *seems* there isn't anything else wrong in there. Still, don't want to buy a new thermostat and that not be the problem. Suggestions on how to diagnosis the problem?
AC is Rheem and thermostat is robertshaw 9420, powered by 24v (no batteries.)
