Unplug it and do a continued check between the prong,

Low refrigerant levels (most common cause.) it sounds like your outdoor unit is running, but the AC is blowing out hot air, start with cleaning the condenser coils. Spray the coils with a water hose, clearing away the loose dirt and foliage. If the AC continues to blow warm air, call an HVAC expert for help with refrigerant levels.

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. https://www.google.com/search?q=Carrier+Heat+Pump+Model+25HBC+service+manual ..

Get yourself up to the machine on a safe platform. Remove any covers that will come off easy, or tie them up out of the way. Remov e the filters. Often the whole front can be removed by just taking out a couple of screws. Once exposed, look for something out of place. Put the louver back where it belongs to see how the hinge works. It may have jumped out of it's proper position. Ease it back in position and check it for freedom of movement. If it looks good, put it all back together.

I would suggest first removing all thermostat wires from their terminals on the control board. Does fan relay coil de-energize? If not, likely control board problem. Look for stray metal small pieces of wire or screws lodged on or beneath control board before totally condemning it. If the fan relay coil does de-energize, start narrowing issue down by connecting thermostat wires one at a time starting with 24v Red, then 24v Common if present (Brn? ), then Cooling Yellow, Then Fan Green and then Heat White. It could possibly be a short in the thermostat wire.

Looks like 5 tons.

Check the wiring diagram to see if the thermostat is in the heating circuit or not. If the heating element is not getting power the thermostat might be at fault.

The Honeywell RTH2300 doesn't need a C-wire. See the documentation in the Installation & Setup section on the support page: https://www.honeywellhome.com/us/en/support/air/thermostats/programmable-thermostats/5-2-day-programmable-thermostat-w-change-reminder-rth2300b1038-e1/ . If your old thermostat had a C-wire, check the system board at the furnace. Make sure that the G-wire (usually green) at the thermostat is also connected to the system board's G-wire connection. First check the obvious: what is the current position of the fan switch? It should be on auto. (That's the switch on the right.) Is the temperature that the thermostat is reading match the real temperature in the room? Check with a thermometer. If the area near the thermostat is still above (cooling) or below (heating) the set temperature, the room circulation could be a factor. I know my home's thermostat keeps the A/C running for a while after a thermometer on the other side of the living room reaches the desired temperature in the evening when parts of the house are closed off. If the thermostat temperature reading is correct, the signal may not be reaching the system board. You can check that all of the individual wires between the thermostat and the system control board are undamaged. I've seen those thin wires break when you take them off one thermostat and connect them to another. Another possibility is that a relay isn't working. Contact Honeywell if the temperature sensor isn't giving the correct reading. Contact a heating and cooling repair person if the problem is with a relay or the system board. I hope this helps.

No model number so not sure what you got! Could be a bad capacitor could be a bad motor.

Model number is not recognised. https://www.google.com/search?q=carrier+dk4cnb006+wiring+diagram ..

Your blower runs on 240 volts. So 3 wires are speed and 1 is the neutral. Likely white is neutral/ L2 and then you have your three speeds. So you will still have 1 spare 1 for cool 1 for heat 1 for l2/neutral. Model number of motor and unit usually helps for proper diagnostic though.
