    Thermostat reset? https://www.aireserv.com/about/blog/...al-thermostat/ If you could be more specific like what the thermostat is doing, blank, blinking.

    I would replace it with the same thing that failed, but those kinds of fuses are often a symptom of a short in other components. An HVAC store can advise you best, and no I won't tell you to replace the fuse from your car or Auto Zone.

    I think it's possible you blew the fuse when you cut the wires (and saw a spark).
    Try a fuse. Since you're dealing with 24 volts, I think a car fuse of appropriate amp rating will work.

    Good luck,
