Notes:
1. Air side heat exchanger refrigerant outlet temperature sensor and air side heat exchanger refrigerant total outlet temperature sensor connection port is
CN24 and CN69 on the main PCB (labeled 22 and 23 in Figure 4-2.1 in Part 4, 2.2 “Outdoor unit main PCB”).
2. Measure sensor resistance. If the resistance is too low, the sensor has short-circuited. If the resistance is not consistent with the sensor’s resistance
characteristics table, the sensor has failed. Refer to Table 4-5.1 in Part 4, 5.1 “Temperature Sensor Resistance Characteristics”.
3. Check air side heat exchanger, fan(s) and air outlets for dirt/blockages.
