Hi all,

I have got an error code for a Fujitsu 4 head multi. Bulk head indoor Units.

Model: AOTG30LAT4

The error code is: 3 Way Valve Thermistor (Indoor Unit C)

My question is,

Where is the 3 Way Valve Thermistor located and what does it do?

I don't understand why a 3 way valve would have a thermistor. I thought it's purpose was specifically so a system can be pumped down and to hold refrigerant inside the condensing unit. Eg, like when you purchase the unit.

Thanks
