2. Check outdoor P.C. board.
1. Check outside temp. sensor (TO).
2. Check outdoor P.C. board.
1. Check suction temp. sensor (TS).
2. Check outdoor P.C. board.
1. Check outdoor P.C. board.
1. Check temp. sensor (TE, TS).
2. Check outdoor P.C. board.
1. Check outdoor P.C. board.
1. Check power supply voltage. (AC208V/230V ±10V)
2. Overload operation of refrigerating cycle
1. Trouble of compressor (Lock, etc.):
Replace compressor.
2. Wiring error of compressor (Open phase)
1. Check outdoor P.C. board.
(AC current detection circuit)
1. Check case thermostat and connector.
2. Check gas leak, recharge
3. Check full open of service valve.
4. Check PMV (Pulse Motor Valve).
5. Check broken pipe.
1. Outdoor service P.C. board
Check model type setting jumper wire.
1. Check outdoor P.C. board.
