This failure mostly thermostat temperature refrigerant leak drain or contact sticky dead, after cooling to the temperature of the thermostat contacts can not be set aside disconnect the power, long-term power compressor temperature is too high, then power overload protection after a few minutes, been able to reset the power-overload, but still can not start. Demolition of the compressor junction box housing, pull the starter PTC, PTC has been found to burst, PTC starter after replacing the compressor starts running, stopping the machine to a placeholder temperature, which determines the thermostat can not disconnect the power lead to the state failure. The thermostat model DTB-XH401 (Nissan), check the information, after the reign of the thermostat with a factory in Foshan WDF18Q-102 pressure type thermostat (constant temperature reset type) substitution, electricity, the normal operation of the compressor, cooling effect as ever, troubleshooting.tfvservice manual download site
