Check point 3. Check the solenoid coil and 4-way valve
•
Solenoid coil
Remove P60 from PCB and check the resistance value of coil. Resistance value is about 2.085
kΩ (for 09 model) or 1.97 kΩ (for 12/18 models) (at 68 °F (20 °C)).
If it is open or abnormal resistance value, replace solenoid coil.
•
4-way valve
Check each piping temperature, and the location of the valve by the temperature difference.
If the value location is not proper, replace 4-way valve.
Check point 4. Check the voltage of 4-way valve
Check the voltage P60 of Main PCB.
Check if AC 198 V (AC 220 V -10%) to AC 264 V (AC 240 V +10%) appears at P60 of Main PCB.
•
Heating operation
If it is not voltage, Replace Main PCB.
•
Cooling operation
If it is voltage, Replace Main PCB.
Check point 5. Replace main PCB
If Check Point 1 to 4 do not improve the symptom, replace main PCB.
