Customer Question
I have a carrier furnace...
I have a carrier furnace model 58 PAV090-14 the 3amp fuse keeps blowing. I changed motor speeds and it's running ok now. Could it be something in the motor or did I not do anything and it could happen again

If the 3amp fuse keeps blowing you have a short in the thermostat wiring. You need to check the thermostat wiring at the thermostat, any junctions you have for the thermostat wiring and at the control board in the furnace. See what you find. If you are not sure start removing the thermostat wires one at a time and see when it does not blow and then you should be able to narrow it down. If you need more help let me know.
