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.

Ingnition proving failure .Board not sencing flame . Check flame sensor is clean and check connection at board .Check gas to igniter is not blocked .

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.

It sounds as though the ac has done this for a long time,may be since it were new.Does it cool good when it is on?Or does it take a long time for it to do the job?I am thinking,from day one the ac unit was charged,incorrectly,There is air in the system,and not the proper amount of freon.This would give a tech.a false reading if he where to attach ac gauges up to read pressures.It has happened before.The ac units are charged with a machine,and between freon and the machine it traps air,and pushes it in the system.The machine is set to a certain amount of freon to charge.When the machine senses that amount of freon has been injected into the unit,it shuts off.My advice would be to evacuate and recharge the system to spects,with manual gauges.This would assure the right amount of freon,and the tech.would be able to do this with his eyes closed,and know it is done right,ac men know there gauges,I know,for I am one myself.Let me know some feedback on this [email protected]

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.

The E-4 is either a discharge thermistor or the Pc board, in my experiences has always been the thermistor. Hope this helps. Michael I’m happy to help further over the phone at https://www.6ya.com/expert/michael_341f3f9dee622e54

call a furnace repair service locally

Fuse is probably blown. Check thermostat wiring and electric furnace for wiring. Look for 3 amp automotive fuse in furnace and replace
