Judgment and measures

1. Check refrigerating cycle (Gas leak).
2. Trouble of electronic expansion valve.
3. Check discharge temp. sensor (TD).

1. Freezing cycle overload operation.
2. Check outdoor heat exchange sensor (TE).
3. Check outdoor P.C. board.
4. Check high-pressure switch and circuit.

1. Check power supply voltage. (AC208V/230V ±10V)

1. Check screw tightening between PC. Board and heat

sink and check radiator grease.

2. Check heat sink blast path.

1. Check gas leak, recharge.
2. Check full open of service valve.
3. Check PMV (Pulse Motor Valve).
4. Check broken pipe.
5. Check discharge temp. sensor (TD), suction temp.

sensor (TS).

1. Check operation of 4-way valve.
2. Check outdoor heat exchanger (TE), suction temp.

sensor (TS).

3. Check indoor heat exchanger sensor (TC).
4. Check 4-way valve coil.
5. Check PMV (Pulse Motor Valve).

1. Check outdoor heat exchanger sensor (TL).
2. Check indoor heat exchanger sensor (TC, TCJ).
3. Check full open of service valve.
4. Check indoor/outdoor fan.
5. Check PMV (Pulse Motor Valve).
6. Check clogging and short circuit of indoor/outdoor heat

exchanger.

7. Overcharge of refrigerant. Recharge

1. Check lock of fan motor.
2. Check power supply voltage. (AC208V/230V ±10V)
3. Check outdoor P.C. board.

1. When performing operation while taking-off compressor

wire, P26 error occurs. Check control P.C. board.

2. When performing operation while taking-off compressor

wire, an error does not occur. (Compressor rare short)

1. Check control P.C. board.
