Hi. This is Ken Campbell and I'm new to the forum.
I have a Goodman Furnace GMPN080-4 that is blowing the 3A fuse on the control board. The issue is the AC won't work. I replaced the fuse only to have it blow when power was reapplied. Thermostat calls for cooling but I have nothing. AC and furnace breakers are ok. Furnace fuse is good too. I can manually operate the contactor on the condenser and confirm that it is working. Can anyone point me in the right direction please?
