Many consumers choose to buy air-cooled refrigerators at the same time, but also on the use of air-cooled refrigerators and maintenance of the question, for the traditional straight-cold refrigerator to compare the internal structure of air-cooled refrigerator is more complex, more need for professional maintenance help. Here, a brief introduction to the air-cooled refrigerator will appear what common faults.

(1) on the box has a certain frozen, the lower box is not cold

Freezer indoor fan motor damage, resulting in no recirculating cold air to the upper cabinet has a certain degree of cooling, the lower box is not cold. Check the method: cut off the fan motor winding value, if infinity, then the fan motor windings due to damage and damage, need to change the fan motor windings.

Due to defrost heater, superheated defrosting damage or bimetallic frost thermostat disconnect, resulting in the evaporator on the frost layer is too thick, plug the evaporator Alice gap, can not pass through the cold wind. Inspection method: check the defrost heater, superheat frost insurance, bimetallic defrost thermostat status, replace the damaged components.

Defrost timer clock motor coil burned, causing the timer does not work, can not be defrosted according to the program. Maintenance method: check the defrost timer clock motor coil, the normal resistance should be about 7kΩ, contact resistance should be 0Ω. If the defrost timer clock motor coil burns, replace a new clock motor coil.

(2) the whole is not cooling, the compressor and fan motor does not turn

Check if the thermostat is damaged. Check the method: cut off the power, remove the thermostat, to detect the resistance between the two contacts, if infinity, then the thermostat temperature sensor leaked. Replace a new thermostat.

Defrost timer contact burned or too much coke, resulting in refrigerator circuit can not be normal conduction. Check the method: cut off the power, remove the defrost timer, with a multimeter to detect its contacts, if the resistance exceeds 2Ω or infinity, should replace the defrost timer.

(3) the whole is not cooling, the compressor does not turn, but the fan motor turns

The cause of this failure is mainly due to the compressor starting relay problem, the multimeter can be used to detect whether the compressor starts the relay is loose, the contact is serious coke, ablate, find the problem after re-installing the start relay or replace the problem The compressor can be started.
