Goodman energizes it reversing valve in the cooling mode. Usually in the "o" circuit of the thermostat wiring.You may have that wired hot somehow.

3 amp is standard.the fuse is blowing to protect the transformer.It is telling you that there is a short in the low voltage wiring.Goodman also had an issue with the coil shorting on the contactor.To prevent damage.....i'd call a pro.It should be a fairly simple repair.
SOURCE: MY HEAT PUMP SYSTEM WILL NOT WORK IN EMERGENCY MODE
the thermostat sub base has a place to connect a wire usually white to energize the heat strips when you push the stat way hotter than the house temp. that is why the strips come on in normal heat. it also has a terminal that is only energized in emergency heat and it also should have a wire connected to it so that terminal can supply power to the strips when the stat is switched into emerg heat . you can identify the terminal from the wiring diagram and if need be jumper w2 wire over to the aux terminal and it will work. they both go back into the airhandler and power the same strips. w2..................................................................................................w2 in airhandler to strips or w2...jumper to aux......................................................................................................................w2 in airhandler to strips.

usually if the fan failed the heater will overheat maybe the smoke you saw was coming from the heater. Let the repairman to repair the fan.

Here is what I would try to see if the thermostat is bad. Take the facing off the thermostat. Once this is done you will see where the wiring is connected should be a red green yellow and white Turn off power to unit make a diagram as to where the wiring was connected red to r green to g and so on Remove these wires red green and yellow and twist them together Go to the power source and re energize the unit once this is done all components should come on if not the thermostat isn't your problem Red is your low voltage power supply (24 volts) Green is your fan motor in furnance, yellow is your outside cooling unit. 1 other thing you might check. In the furnance if the doors are not properly installed on the face of the furnance it may not allow the unit to come on. There is a safety switch on the furnance where the filter is that if the door is not put on properly the whole system loses power and will not work. Hope this helps. Good Luck
