  Your York Air Conditioner's compressor might run continuously due to several reasons. The thermostat setting could be too low in heating mode or too high in cooling mode, so check the thermostat setting. A faulty fan might be the cause, so you should check condenser air circulation. It could also be due to a refrigerant charge that is too low, indicating a leak, in which case you should find the leak, repair it, and recharge the system. Air or incondensables in the refrigerant circuit can also cause this issue, requiring you to remove the charge, evacuate, and then recharge the system.

  If your York Air Conditioner's compressor starts but shuts down quickly, it could be due to several reasons. There might be too much or too little refrigerant, requiring you to remove the charge, evacuate, and recharge the system. A faulty compressor could also be the cause, so determine the cause and replace the compressor. Another possibility is air or incondensables in the refrigerant circuit, which also requires removing the charge, evacuating, and recharging the system. If you have a heat pump unit, a damaged or blocked open changeover valve could be the problem, and you would need to replace it.

  If the outdoor fan of your York Air Conditioner runs but the compressor doesn't start, it could be due to a motor winding that is cut or grounded; in this case, check the wiring and the compressor winding resistance. Another potential cause is a faulty capacitor; if this is the case, find the cause and then replace the capacitor.

A fuse might be blown, or a circuit breaker open, so replace the fuse or reset the breaker. Low voltage could be the issue, so find the cause and fix it. A faulty contactor or relay could also be to blame, so replace the faulty component. Check for loose electrical connections and retighten them. Ensure the thermostat isn't set too low in heating mode or too high in cooling mode. A faulty capacitor could be the cause, so find the cause and then replace the capacitor. Check for incorrect wiring or loose terminals, and check and retighten them. Finally, a pressure switch might have tripped, so find the cause befor...
