    If it is a fuse, it likely is one of the bigger ones, meter will make short work of this. If Cartridge fuses, changing both is quick, easy and cheap.
    Or a Meter to show where voltage is stopped.
    Check not only the Fuses/breakers at the panel. But check disconnect at each unit(air handler and compressor)

    Thermostat/AC unit is missing an anti-short cycle timer. It can blow fuses and fuseholders to bits. Likely the big fuses to the AC unit are popped.

    Bet the stat is mechanical.

    I do have an extra anti-short cycle timer.
