safety first
Before carrying out refrigerator maintenance and pressure measurement, make sure that the refrigerator has been turned off and disconnected from the power supply to ensure safety.
Prepare tools
Take out your air conditioner refrigerant pressure gauge and connect it to the refrigerant inlet and outlet of the refrigerator, ready to start measuring the pressure.
Measuring pressure
Open the valve of the pressure gauge to let the refrigerant flow into the instrument, and pay attention to the reading of the pressure gauge. The refrigerant pressure should be within the normal range. Please refer to the refrigerator manual for the specific scope.
exception handling
If the pressure is abnormal, there may be something wrong with the refrigerator. Check the tightness of the refrigeration system, clean or replace the filter, or adjust the refrigerant charge and discharge.
Maintenance completed
After measurement and maintenance, remember to close the pressure gauge valve and disconnect the pressure gauge from the refrigerator. Don't forget!
Professional and technical personnel
Repairing refrigerators and measuring pressure require professional knowledge and skills. If you are uncertain or inexperienced, remember to ask a professional technician for help!
