Troubleshooting.

LANGKAH PANTAS MENCARI PUNCA KEROSAKAN
*Komponen2 yang perlu diperiksa:-
a) Fius
b) Overload
c) Phase Protection Relay
d) Thermostat
e) High & Low Pressure Switch
f) Relay
g) Timer 24 Jam/Defrost timer
h) Step Timer
i) Squence Timer
j) Contacter
k) Remote Control
l) P.C Board
m) Periksa Tekanan Gas 

Sistem Tidak Beroperasi - Check Elektrikal

a) Test Supply – R Y B Untuk:
- Contactor Blower
- Contactor Pump
- Contactor Cooling Tower
- Contactor Compressor
- SEMUA CONTACTOR

b) Sekiranya semua supply ada (maknanya tiada short) litar kawalan saja yang bermasalah.
-Periksa:
1. Overload
2. Thermostat
3. High & low pressure switch
4. Oil pressure Swicth
5. Timer 24jam /defrost timer
6. Phase protection relay
7. Relay
8. Contactor
9. Step timer
10. Squence timer
11. Remote control
12. Pc board
13. Water flow switch
14. Auto gate valve (actuator valve)
15. Air flow switch
16. Pendawaian
17. Motor blower
18. Motor condensor fan
19. Compressor oil
20. Water pump motor
21. Cooling tower motor
22. Capasitor
23. Heater elemen

Sistem Beroperasi tetapi Tak Sejuk - Check Mekanikal
-Periksa:
1. Tekanan gas
2. Evaporator coil
3. TXV
4. Belting
5. Filter drier
6. Stainer
7. Capillry tube
8. Condenser coil
9. Paip gas (pecah/bocor)
10. Compressor
11. Water pump
12. Cooling tower
13. Air Cooling Tower

Petua:
Air-cond langsung tak boleh ON - check elektrikal
Air-cond boleh ON tapi tak sejuk - check mekanikal
