Where are the fuses located in a carrier heat pump

Carrier says they carry them on their website. Really though, you need a qualified engineer with gauges and refrigerant gas. There isn't much you can do yourself.

Unplug it and do a continued check between the prong,

You have a low voltage short, likely on the wire leading to heat pump, first place I'd check anyways. They do make a resetting fuse that will help you until you can locate the short but can be a daunting task. Take a pic of low voltage wires at heat pump. unhook all wires and wire nut. replace fuse and turn power back on. if fuse holds its inside the heat pump if not...keep looking!! Best wishes

Miss wired or shorted low voltage wiring. Have you changed stat? Animal chewed wires at foundation wall or in attic?

check the thermostat also check the inline fuse for the electric heat coil . check wires in control panel they tend to burn and last check to make sure reversing valve is changing over located by the compressor

If this is a split unit there is two brakers one in the house at the panel and one at the outdoor unit it should either have fuses or a breaker inside the box.

Starting Amps will be 3 times of running amps. Change the fuse wire accordingly.

Try searching this Carrier web site. It has lots of manuals.
Hope this helps.
