Hi,

when a fuse blows, its telling you that theres a fault. this could be a loose or broken wire.
or alternatively, the fuse rating is too low. you could check the wires are tight. and also possibly try fitting a 5 amp fuse. check first that the fuse is rated correctly for the appliance. usually 3-5 or 13 Amps.

That fuse should be a 3 amp fuse. There is either a problem in your wiring, your A/C contactor or the board.

Try increasing the rating of the fuse (3-5 AMP.) If it blows up again, there might be something wrong w/ the circuit

Fan will not cut off even in auto position. It just keeps running


If the fan will not turn off when the thermostat is turned off the thermostat is not the fault. It could be the wiring from furnace to thermostat. Disconnect the thermostat wiring from the furnace to isolate the possible problem component.

Amp fuse keeps blowing


The component being protected by the fuse is drawing excessive current - has to be a board or something because the motor always draws more than three amps. Check the units schematic for locating the possible offending board. Must be relatively new since you indicate it is multispeed. Still under warranty?

Control fuses only blow with a 24 volt problem. Make sure that you replace it with a fuse NO LARGER than 5 amps.You could have a thermostat wire pinched or some wire touching the cabinet inside the unit, but it is a 24 volt problem.

My carrier furnace keeps blowing 3amp fuse when I turn thermostat to cool.


Hello, sounds like there is a short in the low voltage circuit. First inspect the wiring at the control board and make sure nothing is loose or touching metal. Also, inspect the wiring all the way to the outside unit and make sure it is not loose or touching metal on the outside unit. If you dont see anywires loose then you will need a meter to check the wires for continuity to the common terminal on the board with furnace and ac turned off.

Goodman furnace


double check your wiring. R terminal on the furnace will provide 24 volts to the t-stat. W terminal in the t-stat will send 24 volts back to the furnace W terminal to turn on the heat. G terminal in the t-stat will send power to the G terminal in the furnace when the t-stat is switched to fan on. Y terminal in the t-stat will send power to the Y terminal in the furnace which in turn will send 24 volts to the A/C outside. The C terminal in the furnace should be connected to the c terminal in the A/C outside as well as to the T-stat. Check the fuse again

Goodman Furnace/AC unit not working 3a fuse blows even after replacement. once thermostat is turned on and clicks to start ac unit the fuse blows


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.

The whole system won't turn on


Go to Logitech support and check the faq's on your speakers. You must replace with the same fuse and it may be a 3amp slow blow fuse. If so replace with the same fuse or you will just keep blowing them out.
