I'm a jack-of-all-trades. My contactor got stuck in the on position (it was pitted and kind of burned). I replaced it with a new one, but stupidly connected the Low Voltage wire to the same side on the contactor. Some wires smoked at the contactor and I shut off the power.
The neighbor (studied for A/C but not working in the field) showed me my error and correctly hooked the LV wire. Afterwards, the 240/24 volt transformer had no power coming out the 24v side. We replaced the transformer and it burned out again. 240 Volts come to it, but 24v don't come out.
I can't visually find a shorted wire from the 240 side back to the blower motor nor at the blower's capacitor. The blower seems to run fine according to the neighbor. There is no circuit board. Another A/C friend told me, over the phone, that it could be the blower motor having a short.
This forum's previous postings suggests a short along the 24V wiring (through thermostat and/or contactor).
Before I call repair man, should I replace the 24V wiring and contactor? Should I replace the blower motor? Thanks to all suggestions, in advance.
