Question about Goodman GMS90703BXA Heater
A/C is not working. Found a 3 Amp.fuse blown on a circuit board inside the blower section. I already went thru bunch of fuses.
Model # GMS90703BXA
It seems like a short circuit, but I don't know where to look. Any suggestions? Thank you.
In more rare scenarios the 24v activated fan relay that is soldered to the circuit board can cause this same problem. I agree with Therinnaiguy, If the fuse is blown 90+% of the time there is a short in the 24 volt control system.

Most likely it's near where the wires got weed wacked outside. Follow the wires from the indoor unit to the outdoor unit. Look for any damage along the way. Also follow any thermostat wires you can find and inspect them. Sometimes where they enter into both the inside and outside units they frey on the metal casing. I hope you find something. Otherwise, you may have a bad transformer sending the wrong voltage to components.
