First, why should there be a separate circuit in the freezer?
Because the same outlet or power supply is used with other appliances, the power supply voltage becomes unstable, and the appliances often begin to cause voltage drops. In particular, when the power reaches the peak, the voltage is too low and the compressor will not start, or in severe cases, the compressor will not stop automatically. In addition, the compressor may be damaged.
Second, the cold air in the freezer is always leaking.
後 After long-term use, the aging and deformation of the door self-sealing strip will cause cold air to leak from the cabinet, reducing its cooling effect.
The inspection method is to first open the flashlight in the cold interior, close the door, and then carefully observe whether there is a gap between the freezer and light leakage, and clean the seal with washing powder. The seal will open and stick. Seal a piece of sealing tape on the original, and then check that it still does not leak. Repeat the test for this patch until the light does not leak.
Third, why can't the freezer start?
1. Whether the power supply voltage is within the specifications. Generally, the voltage should not exceed the range of 187 to 242 V. If it is not within this range, it should be installed by a voltage regulator or a professional electrician.
2. Poor contact between power supply and freezing plug;
3. The ambient temperature of the freezer should not be lower than 5 steps. Otherwise the compressor will not start.
4. The low temperature compensation switch is not turned on, the low temperature compensation switch is faulty, and the low temperature compensation heating wire cannot be turned on.
5. When the temperature controller reaches the zero position, the thermostat will fail.
