Outdoor Unit Pipe Thermistor Assembly
The P8 code specifically identifies an abnormality in the liquid pipe or 2-phase pipe temperature sensor reading. This thermistor is a Negative Temperature Coefficient (NTC) resistor that has likely drifted out of its calibration curve or suffered a failure in its weather-proof encapsulation. Replacing this specific sensor restores accurate temperature feedback to the control logic, allowing the expansion valve and compressor to resume normal operation.
