Common performance faults
Performance faults involve the working conditions of multiple loads. Before analyzing the fault, it is necessary to confirm that the
refrigerator power supply is connected normally and the compressor works normally. System Faults must be maintained to prevent dangers
in strict accordance with the relevant operation specifications. The following table provides the main fault descriptions and troubleshooting
methods for refrigerator. The specific treatment can be flexible according to the situation.
S/N Main fault
The whole machine is
1
not refrigerated
2 Switch in poor condition
Poor refrigeration effect
3 of refrigerator
compartment
Judgment phenomena
The surface temperatures of
compressor and condenser are
both high, and the compressor
power is high
The compressor has high
power and will stop
automatically a couple of
minutes after starting
The compressor operates
constantly with low power and
no obvious heating at left and
right side panels.
The freezer compartment is
normally refrigerated, the
display is always on, and a
buzzer alarm is sounded
The freezer compartment is
normally refrigerated, but the
refrigerator compartment is
not refrigerated or
continuously refrigerated to
below 0 degree, with no fault
prompt
Possible causes
Refrigerant leakage
Solder blockage at the high
pressure end solder joints
The fan of the freezer
compartment is not running (the
terminal is not connected, the
fan is jammed, etc.)
Malfunction of refrigerator
compartment door switch (poor
contact, not installed)
The damper of the refrigerator
compartment is jammed or not
installed by negligence, resulting
in the damper not being
normally controlled
Treatment
Replace process pipes, check
leakage, and refill refrigerant.
Judge the fault point by the
appearance of the solder joints If
it can't be determined, cut the
solder joints in reverse order in
sequence for troubleshooting
and repair
Check the assembly of the
freezing fan
Troubleshoot the door light
switch
Check the status of the
refrigerator compartment
damper
