I have a bryant 395cav042091 +80. Got a new puppy that chewed up the thermostat lead to the cenral air unit outside. I repaired the wires leading to the central air but the furnace is flashing a code 24 (secondary voltage fuse is open) and nothing works. Tried Disconnecting thermostat leads and still flashing 24. Is there a way to reset the system ?
Thanks Nick

Try turning off the breaker to the furnace for a few minutes then back on,, see if that re-sets. Let us know
