Get Your York Air Conditioner Running Cool Again with a Quick Reset


Is your York air conditioner not blowing cold air like it should? Has it stopped working or is it frozen up? Before you call an HVAC technician, try resetting your York AC first. A simple reset can often get your cooling issues resolved and your home back to a comfortable temperature.

Resetting an air conditioner is a quick and easy first step in troubleshooting common AC problems. It reboots the system and clears out any minor errors that could be preventing your York unit from running properly. Many times, a basic reset is all that’s needed to get the cold air flowing again.

In this blog post, we’ll cover everything you need to know about resetting your York air conditioner. We’ll go over how to locate the reset button, what you need to do to reset the AC, when you should try a reset, and what to do if resetting doesn’t solve your issue. Follow along and learn how to get your York AC back up and running in no time.

Locating the Reset Button on Your York AC

The first step in resetting your York air conditioner is accessing the reset button itself. The location can vary depending on the specific model you have. Here’s where you can find the reset button on most York ACs:

Control Board

On newer York AC systems, the reset button is located on the control board. This board is housed in the indoor furnace unit, so you’ll need to remove the front cover panel to access it. This panel is typically secured by some screws that you’ll need to remove.

Once inside, look for a button labeled “reset” – it may be red or blue in color. The control board will contain the diagnostic lights and electronics that operate your York air conditioner. The reset button is designed for rebooting these controls when needed.

Blower Motor Housing

For older York air conditioner models like the Diamond 80, you can find the reset button on the blower motor housing itself. To access this, you need to remove the circular blower motor cover located on the front of the furnace unit.

Behind this cover is the blower motor. Look on the housing around the motor for a small red or blue reset button. This button on the motor housing allows you to quickly reboot the York AC system.


Some newer York ACs have a reset button integrated right on the thermostat. If you have a digital LCD thermostat, check the menu options for a “reset” selection. Selecting this on the thermostat interface can remotely reset the air conditioner.

So in summary, the most common places to find the reset button are:

  • On the control board in the furnace unit
  • On the blower motor housing in older units
  • Built into the thermostat on newer models

Check in these locations to access the reset function on your York AC.

How to Reset Your York Central Air Conditioner

Once you’ve located the reset button, resetting your York air conditioner is a simple process:

Step 1: Turn Off Power to the Furnace

Before resetting the AC, you need to turn off power to the furnace unit. This is an important safety step whenever working on an HVAC system. Locate the furnace power switch or circuit breaker and turn it off.

Step 2: Press and Hold the Reset Button

With the power off, press and firmly hold the York reset button for 5-10 seconds. You should feel or hear a click when the reset engages.

Step 3: Restore Power to the Furnace

Head back to the furnace power switch or circuit breaker and turn it back on. This will restart the York air conditioner.

Step 4: Allow the York AC to Go Through its Restart Sequence

When power is restored, the York air conditioner will go through its full restart protocol, just as it would during a normal power cycle. The blower fan will run briefly, the compressor will click on, and the system will resume operation.

The reset process realigns the AC controls and clears any minor faults preventing normal operation. After a successful restart, your York air conditioner should be blowing cold air once again.

When to Reset Your York Air Conditioner

Resetting your York AC is recommended if you experience any of the following issues:

Air Conditioner Not Turning On

If your York air conditioner isn’t turning on at all when you set the thermostat to cool, a reset can help. Start by making sure power is on to both the furnace as well as the outdoor AC unit. If power is on but the system still won’t start up, then a reset may get it going again.

Frozen Evaporator Coil

If your AC coil has become frozen, preventing cold airflow, a reset can help unfreeze it. After resetting, set your thermostat to fan mode only for an hour. This will allow the fan to blow over the coil and thaw out any ice buildup so cool air can flow freely again.

Blower Fan Not Working

A blower fan not starting up to circulate air is another issue a reset can fix. The reset restarts the fan controls and gets it spinning again. Just make sure the fan itself is not mechanically jammed or obstructed first.

Temperature Control Problems

If your York AC is running but not cooling properly or maintaining the set temperature, resetting can recalibrate the system. A simple reset realigns the sensors and settings governing the temperature control.

Error Codes on the Thermostat

Diagnostic error codes often point to a system reset being needed. If your thermostat displays an error that won’t clear on its own, try resetting the York AC to reboot the system and clear the code.

In general, if your York air conditioner exhibits any odd or intermittent behaviors, performing a reset is recommended. It takes only minutes and often resolves cooling performance problems.

Next Steps if Resetting Your York AC Doesn’t Work

While a system reset fixes many minor issues, sometimes it’s not enough to get a York air conditioner running properly again. Here are some next steps to try if resetting your AC doesn’t resolve the problem:

  • Make sure the air filter is clean and unobstructed. A dirty filter can prevent proper airflow.
  • Check that electrical connections are intact on the furnace, AC units, and thermostat wires. Faulty power supply can cause operational problems.
  • Test the condenser and evaporator fan motors. If either fan is not spinning, it indicates a bad motor.
  • Test the start and run capacitors. Bad capacitors are the most common reason an AC compressor won’t turn on.
  • Check the AC refrigerant charge. Low refrigerant levels reduce cooling performance. There may be a leak if levels are low.
  • Inspect the condenser coils. If they are significantly dirty, the AC will not run efficiently.
  • Evaluate the thermostat. Malfunctioning thermostats can prevent proper AC operation.

If you’ve verified these areas and your York air conditioner still isn’t working right after a reset, then it’s time to have an HVAC technician perform a complete diagnostic service. Professional troubleshooting can identify any underlying defects impacting normal operation.

Resetting your air conditioner is a handy first step in addressing cooling problems, but sometimes a repair may be needed if issues continue. Get professional help to properly diagnose and fix your system if a basic reset does not restore proper functioning.

Reset Your York AC Unit for Quick Cooling Relief

When your York air conditioner acts up, don’t immediately think you need expensive repairs. Many common AC problems can be resolved with a simple system reset. Locate the reset button, press and hold it for 5-10 seconds, then restart your AC.

Resetting reboots and recalibrates the air conditioner controls. It clears up minor errors preventing normal operation. Make sure power is off before resetting your York AC unit. Then monitor it as it goes through the restart process. The system should resume cooling your home after a successful reset.

Try resetting your York air conditioner first when troubleshooting issues. Doing so is fast and easy. It often gets the cold air blowing once again without the hassle and cost of professional service calls. However, if your AC still doesn’t work right after resetting, contact an HVAC technician to properly diagnose and fix the problem. A reset clears up basic issues, but major system defects require repair by a qualified professional.
