Gas leakage,

 

Discharge temp. error,

disconnection of TS/TC

 

gas leakage

sensors (Check code 02, 1C)

 

(Check code 03, 1E)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Valve drive check

 

 

NO

 

 

Is coil of the pulse motor valve

(P.M.V.) correctly set?

 

 

YES

 

 

 

 

 

 

NO

Is connecter of coil connected to inverter?

YES

Is positioning sound of valve (sound hitting to stopper) heard

from valve when the air conditioner starts the operation after turning off power NO of the air conditioner once?

YES

Are temp. sensors of indoor/outdoor units correctly set to the holder?

 

NOTE :

NO

The temperature sensors which are used to control pulse motor valve

 

 

include indoor heat exchanger sensor (TC), outdoor heat exchanger temp.

 

sensor (TE), outdoor suction temp. sensor (TS) and outdoor sensor (TO).

 

 

YES

 

 

 

 

 

 

Set it correctly.

Set it correctly.

Replace coil valve.

Set it correctly.

Gas amount check and valve clogging check

Remove TC sensor connector from the P.C. board in indoor unit. (Remove connector from the P.C. board.)

Operate the air conditioner in COOL mode by TEMP button (“Beep” sound is heard if keeping pushed for 10 seconds.).

The operation enters temporary operation mode which fixes opening degree of compressor speed. Check condensation at outlet of PMV, and then check operating pressure from the service port.

Existence of condensation at outlet of P.M.V.

YES

If there is condensation at outlet (1/4 inch=Ø6.35mm valve side),

 

the valve is clogged.

 

Check the operating pressure from service port, and add gas if pressure is low.

Replace valve.

Add gas.
