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 avometer .
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
Ω
); 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 the refrigerator to be placed unsteadily ,causing
stronger vibration and noise during its operation .
b) Leveling screws not properly adjusted
