Regular inspection to prolong the service life of commercial refrigerators
1. Check the door seal to ensure the cooling effect and power consumptionFirst check the door seal of the freezer, because the door seal not only affects the power consumption and heat preservation effect of the freezer, but also affects the life of the refrigeration compressor. A good-quality door seal has a good suction force, and when the refrigerator door is opened, there will be obvious resistance. If not, it indicates that there is a problem with the quality of the door seal.
2. Check the freezer to ensure cooling efficiency The freezer compartment of the freezer is generally made of aluminum plate material. Check whether the aluminum plate in the freezer compartment has obvious cracks, check whether there are cracks or wrinkles in the flat part, and whether the thickness of the inner tank plate is uniform.When checking the refrigerator, pay attention to whether the mechanical thermostat rotates flexibly, press the defrost button, and observe whether it can rebound quickly or whether the electronic temperature control temperature is accurate.
3. Power on and test run, check product performance After the above inspection, you can turn on the power for trial operation, adjust the thermostat knob to a certain position, connect the power supply, and check whether the light switch and bulb are normal. When the power is turned on, attention should be paid to the starting performance of the compressor and whether it can be started at one time.
4. Check the condenser and observe whether the freezer is operating normally After the freezer has been running for a few minutes, touch the condenser of the freezer with your hands. If there is an obvious sense of heat and the heat is relatively rapid, it means that the freezer is operating normally.
