    A model DGAD Evcon Furnace blew a 3 amp fuse
    When I put the fuse back, the 120/24 volt transformer sparked and threw the breaker. Would I be safe putting in a new transformer? It had no lights blinking because the breaker blew.

    If there is a short somewhere, it will fry yhr new transformer
    Put a inline fuse holder (automotive type)with fuse and if you have a short it will blow the fuse not the transformer until you find the short
