  • Adjust the thermostat setting to cooling mode.
  • Check the refrigerant level and recharge if necessary.
  • For a faulty compressor or issues with the run capacitor, replace it.

3. York Central Air Conditioner Won’t Run

Power problems or a power outage will cause your York air conditioner not to run. Capacitor issues will also cause your AC unit not to run.

If the contractor is faulty, then it will not send voltage to the condensing unit, which will affect cooling, and due to this, your York AC may not run.


  • Check the circuit breaker if it’s power problems
  • Replace the capacitor for your condenser fan motor.
  • Replace the contactor.

4. York Fan Not Working

First and foremost, if your fan motor has no power, it could cause it not to function, so be sure to check whether it has power. If your condenser fan motor is still not working, this could be due to failed capacitors or a damaged motor.

The capacitor supplies power to the fan motor, and if it malfunctions, the fan will not work. Also, check for a broken belt if you do not find the above problems.


Replace the capacitor and also the fan motor.

5. York Blower Motor Problems

Several things could cause your york air conditioner fan to have problems and not function as expected.

First, ensure that the blower fan motor gets power; if it’s not receiving power, it will not run.

Next, go further to check whether the blower motor is burned out and check whether the blower motor is having trouble spinning.

If the fan motor is obstructed by something, it will not spin as required and will only produce a humming sound.


  • Make sure the blower fan motor is getting power.
  • Replace the blower fan motor if it’s burnt out.
  • Get rid of any obstructions blocking the fan’s spinning path, causing the blower motor not to spin.

6. York Air Conditioner Leaking Water

One of the most common causes of a leaking York AC is a clogged condensate drain line. So when the drain line is clogged with dirt and dust, water will back up into your home and start leaking.

A damaged or rusted drain pan and a dirty filter will also cause your air conditioner to leak.


  • Be sure to clean the condensate drain line and remove debris and dirt.
  • Clean or replace the dirty filters for your AC unit.
  • Replace the damaged or rusted drain pan.

7. York Air Conditioner Coil Problems

If your AC system has insufficient refrigerant levels, you will have frozen coils. Another reason for frozen coils is the accumulation and formation of ice due to dirty and clogged coils.


  • To solve this, try to remove the formed ice by using a dry cloth to do so.
  • Clear all dirt from the coils and make sure they are not clogged.

8. York Freeze Protection Disabled Bad Sensor

Most York AC brands highlight an indoor regulator sensor behind the control board, which measures the temperature inside the evaporative coils.

The sensor also protects the compressor from freezing conditions that would cause the liquid to return to the compressor due to low suction.

So if the York air conditioner is experiencing a bad sensor, then the freeze protection will be disabled.


Contact an HVAC technician to help you solve the issue.

9. York Rooftop Unit Troubleshooting

Troubleshooting your rooftop-mounted York AC problems typically involves checking AC parts such as the air filter, condenser coils, and thermostat. Any issues in these air conditioner parts will make troubleshooting your rooftop unit even harder.


  • Change or clean your air conditioner’s air filters.
  • Clean the condenser coils to restore the required operation.
  • Check the thermostat and make sure it’s set accordingly. A wrong thermostat setting could be the reason behind your cooling woes.

How Do you Reset your York AC?

You can reset your York air conditioner without even calling an HVAC technician. However, several reasons could force you to want to reset your air HVAC system.

Below are some of the steps you need to follow if you’re resetting your AC unit.

  1. Turn off your air conditioning unit using the thermostat. This is the first step as you do not want your AC unit calling your AC system for cooling before resetting it.
  2. Now search for the breaker box. Here, you will be looking for a metal box or panel placed flush against the wall. It’s mostly in your garage, laundry room, basement, or closet.
  3. Once you find the breaker box, shut it off. The breaker switch mainly runs to your central heating and air conditioner.
  4. Wait for a minute before switching the breaker box on.
  5. Wait another 30 minutes before switching on your AC’s thermostat.
  6. Once the 30 minutes wait is over, please turn on your thermostat and set it to your preferred setting. Set the thermostat at least five degrees below room temperature to ensure the thermostat is working correctly.

If doing all the above does not get your air conditioning system running correctly, then be sure to contact an HVAC technician to look into the matter. Wait until the technician gets there, do not continue trying to troubleshoot the issue.

York Air Conditioner Error Codes

Below are some of the error codes you can watch out for.

C9-Indoor room thermistor open/ short

When you see the C9 error code, check your air conditioner’s heat exchanger thermistor connection. Also, be sure to check the room thermistor resistance.

E1- Room temperature sensor failure

When you see this error code, your air conditioning unit is trying to tell you that it could be experiencing a faulty thermistor, faulty connector connection, and a faulty PCB. If the problem is a defective connector, you can try turning off the air conditioner at the power switch and restarting it.

E4- Indoor EEPROM error

The Electronically Erasable Programmable Read-Only Memory (EEPROM) error is caused by faulty EEPROM data, faulty PCB, or a faulty EEPROM.

E7- Communication fault between indoor and outdoor unit

This type of error code is caused if the communication wiring is disconnected, the outdoor PCB is broken, or the module PCB is broken.

E14-Indoor fan motor malfunction

Error code E14 is caused if the operation is halted due to a wire breaking inside the fan motor. It could also be the fan motor overheating or a faulty indoor unit PCB.

F4- Overheat protection for discharge temperature.

This error code is caused if the electronic expansion valve is defective. A faulty thermistor and PCB also cause it.

F6- Heat exchanger overheat

This error code means that the air discharge of the outdoor heat exchanger could be clogged with dirt and debris.

York Air Conditioner Maintenance

Maintaining your Yor air conditioner as frequently as possible is very important as it ensures your air conditioner serves you the longest and prevents its parts from wear and tear.

In most cases, the AC manual always indicates how often you should do maintenance, so e sure to follow the manufacturer’s instructions.

Below is a step-by-step guide to maintaining your air conditioning unit.


As we’ve mentioned a couple of times, clogged and dirty air filters will always cause problems whenever your air conditioning system operates. Air filters work but prevent particles from infiltrating the room whenever your AC system is operating. However, an air filter will work best if it’s clean and is not clogged.

Cleaning them regularly and replacing them is very crucial. It would be best to inspect the air filters for dirt, debris, and dust at least once a month.

Outdoor Coils

AC coils function by helping refrigerant absorb heat and cool your room, and over time these coils become insulated with dirt which reduces the amount of heat they absorb. Unfortunately, your air conditioning unit works extra hard to cool your room.

So always ensure the outdoor unit coils are not clogged with dirt, debris, or dust. You could try using a brush or vacuum cleaner attachment to clean the coils and be extra careful, as the coil fins can easily damage.


In every air conditioner, there’s a condenser and an evaporator with fins, and over time these fins can bend and cause insufficient airflow. So to ensure that your AC performs as expected, always check the fins and make sure they have not bent.

Condensate Drain

The condensate drain is essential as it allows the condensation created within the system to drain outdoors.

However, over time, the condensate drain can become clogged, which may hinder drainage; hence you need to frequently inspect the condensate drain and make sure it’s draining properly.

Final Words

As a homeowner, your York air conditioner is the most important investment, and from time to time, it can experience problems if it’s not maintained correctly. However, you can evade these problems by regularly maintaining your York AC. You can always go extra and contact an HVAC technician to help you maintain your AC system.
