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.

you probably purchased a 4 wire thermostat which we call heat/cool you stated you have 6 wires which signifies a heat pump you have to purcahase a heat pump thermostat and then write down the color of the wires to there related spots example...yellowe-y red-r white- w and so forth also before you do this kill the power the voltage typical for residential is only 24v's but if the wires touch you could blow a fuse

Wire nut or tape the black off. The red is normally 24volt supply power to the t-stat. Blue may or may not be the common. Have a voltmeter?

You may and an anolog stat and the old one was digital if so it won't work. Digital sends info to system anolog is just a set of points open or closed. Digital can carry tons of info to system like a computer. Like comparing a computer to a rock. Sorry but you need to go back to proper type stat.

Look at the contactor on the condensing unit, remove the low voltage wires to the contactor and turn on the system. If the low voltage fuse doesn't blow, replace the contactor.
