•
Solenoid coil
Remove CN30 from PCB and check the resistance value of coil. Resistance value is 2.085 kΩ
(at 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.
