Fault Analysis and Troubleshooting for Air Conditioner


1. The principle of troubleshooting
From indoor to outdoor, side parts to central components, fan motor to compressor. Please listen to and ask the user carefully about the fault and information related, then make a judgment based on your experience and check the units regarding the fault description. Please do not remove any part blindly or the fault might be expanded.

2. Preparations for troubleshooting
1) Please check whether the power supply has voltage and whether the voltage is in accordance with the operation requirements of A/C (single phase: 198V-242V; three phases: 342V-418V);
2) Please check whether the power wire, the indoor and outdoor connecting line is correct and reliable;
3) Please check whether the wire insulation is damaged.
