The location of the evaporator temperature sensor
always fixed on the suction tube as attached
(sometimes it fixed on the right middle of the
evaporator).
Take off the evaporator temperature sensor ,and
Measure the resistor , if sensor is bad ,change a new
one.
Meanwhile, measure the resistor of wire plug, If the
resistance
figure
shows
infinity,
that
means
connection between the main board and wire plug
have problem. the detail method as above.
The solution for “E3”problem:
According to above two principle, to check both above
◆
The common problem judgement method
Problem
Cause
Refrigerator can’t
start
1.1 Is the power cord connecting well
？
1.2 Is the power voltage too low
？
1.3 Is the sensor irrational setting?
1.4 Is the ambient temperature too low?
1.5 Is the circuit on power?
1.6 Is there some default in compressor
1.7 Is the refrigeration system blocked by ice or dirty, please stop the unit
and
restart after 10 minutes to see if the compressor can start.
Weak cooling effects
2.1 Is there any heat source around the refrigerator?
2.2 Is there enough space around the refrigerator for rejection of heat?
2.3 Is the setting of the temperature appropriate?
2.4 Is there too much food or overheating food in it?
2.5 Does there open the door frequently?
2.6 Is the door completely closed?
2.7 Does the gasket destroyed or distort?
2.8 Does the gas leak?
The unit can not stop
running
