When thermostat called for furnace power up the 15amp fuse blew. I pulled the fuse and traced the wire to the input of the furnace. I cut that wire and tested for a short... No short in the wall wiring... Since the problem appears to be in the furnace itself I tried to pull the furnace out to check it out. Found the control circuit card was loose inside of the cabinet. Can't see any screws or bolts that are holding the furnace in but I cant see how to pull the furnace up and away from the intake and exhaust ports. Is there a trick to pulling the furnace unit that I am not aware of?

Tapped the exhaust and intake pipes lightly and the unit came out nice and easy... Now the work begins to determine why the control circuit card was loose and why the unit doesn't work
