The 3 amp fuse is in the red low voltage (24 volt) thermostat wire
and only gets power when the thermostat is set to turn on heat or a/c It should be connected to the red wire from the thermostat
the 3 amp fuse protects low voltage side of transformer. if it's blowing on a call for cooling wire pair going to outside unit bad or contactor in outside unit.
Wire tstat normaly> Take the Y off the tstat and it goes to the outside unit. The other wire from the outside init goes to the common off the transformer. This is marked with blue,brown or black. Russ
most of the time its out by the ac unit . you have a shorting thermostat wire .. the outside unit has a large wire thats 240v and a small one that 24v thats the one you want to look at . look for bare wires , look where it goes into the wall , thats the common place . "critters" love to chew thermostat wire . so take a look . .....please rate this answer , i need votes . thanks
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.
