and/or door seal
Analysis of Trouble
When the heat-insulation layer inside the case body deteriorates or the door seal is not
closely touches the door frame, the temperature in the refrigerator will rise and makes the
compressor running continuously.
Remedy
Check the heat-insulation layer for its damaged parts, repair it to improve its
heat-insulation property. If the door has deformed or the door seal is not tightly sealed
against the case body, repair them, respectively.
5) Too much food is placed in the refrigerator, or is placed too densely, resulting in poor
ventilation or poor conditions for temperature sensing, and hence no stoppage of the
compressor.
6) Too high ambient temperature, poorer ventilation and heat dissipation make the
compressor running without stop.
F. Electric leakage of refrigerator
1) Slight electric leakage
Electric insulation has deteriorated due to being affected with damp, thus resulting in slight
electric leakage.
2) Serious electric leakage
Refrigerator case has become live due to faults occurred in some electric devices or the
erroneous wiring in installing power cord plug or outlet by the user. This is very dangerous.
3) Electric leakage test
a) Slight electric leakage
A tingle sense will be experienced as soon as you touch the metal parts of the refrigerator
with your hand .When you test them with a test pencil ,its neon lamp will come on .In that
case ,the first thing you need to do is to determine whether the grounding is perfect .If the
grounding is no problem ,turn off the refrigerator immediately ,then check the insulation of
electric circuits with an multimeter.
b) Serious electric leakage
Never touch the case body of the refrigerator ,its door handle or other metal parts with your
hand .Test the refrigerator with a test pencil ,it will light up intensively ;measure the
resistance between the power cord plug and the case body with an avometer ,the reading
will be zero (0
); in the worst case ,the fuse will be blown .Check the 3-prong outlet to see
whether the live wire and the null line are inversely connected ,this makes the ground
protection lead-out from the power cord plug being connected to the live wire .Another
possibility is that the live wire and null line of the outdoor power supply circuit have been
inversely connected accordingly ,this makes the null line become a live wire .
G .Stronger vibration and loader noise
1)
Refrigerator placed improperly
a) Uneven ground
Uneven ground will cause there frigerator to be placed unsteadily ,causing stronger
vibration and noise during its operation .
b) Leveling screws not properly adjusted
If the leveling screws on refrigerator legs have not been adjusted properly ,vibration and
