Part 3 Principle of Electric Control

Brief Description of Control Principle

HRF-347F is the forced air cooling refrigerator with two doors. A electrical type of all the control is generally adopted. The thermostat directly controls the start and stop of compressor, and hence the refrigerator temperature. Low Temperature Compensation in the above schematic diagram, When the ambient is below the set temperature, the switch will be closed and the heating will work, thus ensuring the normal start, and operation of refrigerator at lower ambient temperature, in such case, the freezer compartment temperature can reach a good point.

Part6. Troubleshooting and Repair

6.1 Normal Phenomena—Not Troubles for Refrigerators

In a domestic refrigerator, there is not only a complicated electric control

system, but also a refrigerating system that is difficult to discern whether

it is in a good working condition. Both the systems are related and affect

each other. If a certain part of a refrigerator works abnormally .Its

refrigerating efficiency will decrease, operation properties will become

unstable, or even it cannot be used normally for those serious cases.

Refrigerators are generally of larger volume, once troubles appear, to

8

send them to a service department is really a tough thing, if such is the

case, the user will always be in suspense, sometimes, normal phenomena

will be erroneously regarded as troubles. Therefore, before we deal with

the topics of frequently occurring troubles of refrigerators and their

remedies, we should firstly give a brief account of some normal

phenomena which are not troubles .In case any one of such phenomena

occurs, there is no need to worry about it, and the user can use it at total

ease.

1). When the compressor of a refrigerator has just stopped running, a

rumbling sound can be heard from inside its evaporator. This is a sound

caused by the flowing of refrigerant in the evaporator tubing. Because the

pressure difference is still greater after the compressor has just stopped

running, the refrigerant will flow for a certain time; therefore, this sound

is a normal phenomenon.

2). A click sound can often be heard from the refrigerator. This is a

normal sound produced by the pull-in or release of the armature of a

current deadweight start relay when starting the compressor .The

compressor motor will produce a slight and uniform sound while it is

running. This sound is not easy to be heard in the daytime, but of course it

can be heard distinctly at night.

3).The compressor consists of an electric motor and a compressing

apparatus .During its normal operation ,the motor’s stator core and

windings will rise to a temperature in the range of 100℃~110℃ ,and the

9

temperature of the piston and cylinder of the compressing mechanism can

also reach as above 100℃ due to the heat produced when compressing

refrigerant .Most of the heat radiates to the air through the compressor

casing ,therefore ,its casing is generally at a temperature between 85℃

~90℃ ,it is very hot ,particularly in summer when the ambient

temperature is higher .All these are normal phenomena .

4). For the forced air cooling refrigerator, a kind of irregular crack sound

can be often heard when the compressor is running for a certain period of

time or has just stopped its running. The stress relief due to expansion and

contraction causes this sound when temperature changes, and will not

affect the normal application of refrigerator.

6.2 Common Troubles in Refrigerators and Their Remedies

Causes for troubles occurring in refrigerators are closely related to the

quality of components and workmanship in assembling by manufacturers

as whether refrigerators are properly used and maintained .The

parameters generally used to express the working conditions of a

refrigerator include the temperature inside the refrigerator, operation rate,

electric power consumption, noise level, and other functional indexes .If

any one of these parameters is beyond its permissible range, this indicates

that there is a fault or trouble in the refrigerator.

During the whole service life of a refrigerator, the probability of troubles

occurring within a union time is called its failure rate. Making a

comparison between the control circuit system of a refrigerator and its

10

refrigerating system, we can find that the failure rate of the former is

higher, and that of the thermostat is the highest. In troubleshooting, the

first thing you must do is to determine where the trouble comes from ---

the control system or the refrigerating system. There is general no trouble

indicating instrument mounted on the domestic refrigerator, locations and

natures of troubles should be determined according to their respective

features, therefore, experience in servicing is very important to

troubleshooting. Service technicians with rich experience can correctly

locate them and take reasonable remedy measures based on their

comprehensive analysis of trouble characteristics as well as operating

conditions for various kinds of refrigerators.

Three Essentials for Checkup

1) Look

a) Check the tubing of refrigerating system for cracks and various

welding points for leaks; if leakage occurs, an oil stain can be seen

definitely .

b) Check the suction and exhaust pressure values (high pressure and

low pressure) of compressor to see whether they are normal.

c) Check the conditions of frost attached to its evaporator and gas

return tube .It is abnormal if frost has formed on part of the evaporator or

there is no frost attached to it. (This criterion is not applicable to the

evaporator of refrigerator compartment.)

11

d) Pay attention to the speed of temperature drop inside both the

refrigerator compartment and freezer compartment .It is abnormal if the

speed of temperature drop is obviously slower than the corresponding

normal speed.

e) Check the environment to see whether it is suitable for placing a

refrigerator.

f) Check refrigerator door seal, case, and table surface and heat

insulation layer.

2) Listen

a) Listen to the noises produced when the compressor is running

Hums from a fully enclosed aggregate unit is the sound caused by

overload indicating that the motor cannot be started normally, meanwhile,

a clattering sound can be heard from inside the start relay, which is

produced because the start contacts cannot be released normally whistling

sound is caused by the high pressure gas flowing out of the crack of the

pressure tube inside the compressor, and clucks are the sound of striking

after the suspended spring inside the compressor has broken.

During the normal operation of compressor, a slight and uniform hum

sound due to undulation of electric current can be heard generally, this is

a normal phenomenon. However, if it sounds like “tong, tong…”, i.e., an

impact sound inside the compressor, this means that a large quantity of

wet vapor of refrigerant or refrigerating oil has come into the compressor

cylinder; if it sounds like “dang, dang…”, a striking sound of metal parts
