My unit is about 14yrs old. We just had siding put up so the box was removed and then re-attached. The unit worked last night, however, when I came home tonight it was not working at all.I checked the circuit breakers (set and Rest), changed the batteries in my electronic thermostat. With a volt meter I checked the fuses in the outside box(good) and the unit is getting volts to the unit. There is no sound coming from the unit at all. I didn't open the unit up as it was getting dark. I would like to narrow down the possibilities myself, I have had electronic and mechanical training, however, I have to say I don't know much about HVAC. How can I narrow down the possibilities, Thermostat, Motor, Fan?
