ac keeps blowing the 5 amp fuse
replace the transformer,fan control board,capacitor,and contactor on condensing unit, once the fuse is replaced the unit will work for a couple of hours and then will blow the fuse again

Do you have any schematics, I, right now am fighting my own AC issues, my condenser unit has no pcbs, no fuses, and no transformers. I need to know at least model, mfg, to check online.

remove the stat off the subbase...disconnect the 24V wires out to the condenser at the condenser power up the air handler again with new 5A and then jump first R to G does it blow? then R over to Y does it blow?

Nice area up north but not being Houston City limits I've found a lot of code violations in homes out there. Not trying to scare you, just so you're aware. Get yourself a drain pan condensate float safety switch for your inside unit. It's required in the city but most homes out there don't have them. It'll protect your ceiling or floor from water damage and let you know when your a/c has a drain restriction. Down here you're drain will be flowing full time with the amount of humidity in the air.
They only cost maybe $20 and are very easy to install.
