Procedure 4.6.4
E5 / E6 / E9 / EA
Temperature sensor connection on
outdoor unit main PCB is loose
1
Yes
Ensure the sensor is connected properly
No
Temperature sensor has short-circuited
or failed
2
Yes
Replace the sensor
No
Replace outdoor unit main PCB
Notes:
1. Air side heat exchanger refrigerant outlet temperature sensor and outdoor ambient temperature sensor connections are port CN9 on
the KHA-06(08,10)RY1 outdoor unit refrigerant system main PCB (labeled 12 in Figure 4-2.2 in Part 4, 2.1 “Main PCBs for Refrigerant System, Inverter
Module”), port CN9 on the KHA-12(14,16)RY3 outdoor unit refrigerant system main PCB (labeled 17 in Figure 4-2.4 in Part 4, 2.1 “Main PCBs for
Refrigerant System, Inverter Module”). Discharge pipe temperature sensor connection are port CN8 on the KHA-06(08,10)RY1 outdoor unit
refrigerant system main PCB (labeled 15 in Figure 4-2.2 in Part 4, 2.1 “Main PCBs for Refrigerant System, Inverter Module”), port CN4 on the
KHA-12(14,16)RY3 outdoor unit refrigerant system main PCB (labeled 15 in Figure 4-2.4 in Part 4, 2.1 “Main PCBs for Refrigerant System,
Inverter Module”). Suction pipe temperature sensor connection are port CN1 on the KHA-06(08,10)RY1 outdoor unit refrigerant system main
PCB (labeled 14 in Figure 4-2.2 in Part 4, 2.1 “Main PCBs for Refrigerant System, Inverter Module”), port CN8 on the KHA-12(14,16)RY3 outdoor unit
refrigerant system main PCB (labeled 16 in Figure 4-2.4 in Part 4, 2.1 “Main PCBs for Refrigerant System, Inverter Module”).
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, and Table 4-5.2 in Part 4, 5.1 “Temperature Sensor Resistance Characteristics”.
