E182 means different things on different Split & Multi-Split models. Enter your model number to see only your reading, or find your model below.

What It Means

  • Suction Temperature Sensor has malfunctioned
  • Suction line sensor RT41 reads open or shorted for 24 hours. Cooling operation is allowed with this fault.
  • Suction line temperature is read by the suction line temperature sensor between Pins 1 and Pin 2 of the 6-pin sensor harness. Nominal Resistance of the sensor is 10K ohms at 77F. The control will display the E182 error code if the sensor reads open or shorted for 24 hours. Cooling operation is allowed with this fault.
