Understanding these error codes helps you solve minor problems quickly and avoid expensive repairs.

How York AC Self-Diagnosis System Works

Modern York inverter air conditioners are equipped with intelligent microprocessor control boards (PCB) that continuously monitor system performance.

The AC system checks several parameters including:

  • Room temperature sensor

  • Evaporator coil temperature

  • Outdoor condenser operation

  • Compressor current

  • Refrigerant pressure

  • Indoor-outdoor communication signals

  • Fan motor operation

If an abnormal condition is detected, the AC will automatically:

  1.  Display an error code on the indoor unit display
  2.  Stop compressor operation if necessary
  3. Activate system protection mode
  4.  Prevent further damage to internal components

This protection system safeguards important components such as:

  • Compressor

  • Fan motor

  • Sensors

  • Refrigerant system

  • Control board (PCB)

How to Check York AC Error Codes

Before troubleshooting, confirm the exact error code displayed on your York AC unit.

Method 1 – Indoor Unit Display

Most York split AC models display error codes directly on the LED display.

Method 2 – Remote Control Diagnosis

Some York models allow error code detection through remote control diagnostic mode.

Method 3 – LED Indicator Blinking

Older York AC units may display faults using blinking LED indicators.

Always write down the exact error code before restarting the AC.
