7. Operation principle and inspection method of main parts
7-1.Compressor
Operation principle
Compressor motor is assembled with the
compressor directly and sealed in the steel
shell. The motor has two groups of
windings: One is starting winding, another
is operating winding. Two groups of
windings are joined inside and formed a
sharing joint.
A lead is drawn outside from every winding
group. Then three leads are jointed
together in the sealed junction and extend
to the compressor shell.
Three lead junctions form a triangular,
distinguished from left to right indoors
separately: Start junction, share junction
and operate junction.
Inspection method
1 Check the resistance of every
winding group of compressor
. Pull down power wire
. Remove relay from compressor
. Measure resistance of every winding group
A.The Max resistance between start junction
and operate junction is composed of start
winding group and operate winding group.
B.The Min. Resistance is one be
tween operate junction and share junction.
The Mid resistance is one between
C.
start junction and share junction.
B+C=A
2) Put Ohmmeter to the Max measurement
and measure resistance of each junction .
If the short circuit is found, the compressor
is out of order.
7-2.Overload protector
Operation principle
Overload protector protects the
compressor through temperature sensor and
electric current
Overload protector is consist of a group of
closed junction and two metal parts.
Overload protector is installed on
compressor external, connected with the
shell of compressor and linked with the
winding group.
If the compressor isn't work, the overload
electric current will make two metal parts heat
to bend quickly, lead the junction to cut off.
Inspection Method
1 Continue to use the ohmmeter to measure
If the overload protector is off, cooled
to room temperature and measure
continually
Although the working of overload
protector can be observed
continually, it is difficult to confirm
parts working well or not according to
If any question, please change same parts.
Temporal measure should change
regular replacement relay in advance.
10
Page 12
Operation principle
Meanwhile, if the compressor motor is
overheat, the effects of electric current and
temperature will lead two metal parts cut off.
If the troubleshooting isn't settled, the
compressor will be worked or stopped with
two metal parts operation cyclically under the
overload condition.
7-3. Relay
This solid relay is different from mechanical relay, which has no coil and movable
junction.
This relay is consist of a little solid wafer. The solid wafer is low resistance (5~33 )
in room temperature, which is installed between two poles.
Inspection Method
When the voltage is existed in the circuit of compressor, the electric current will
pass operate winding group, relay and start winding group. Firstly, low resistance of
relay can make the enough electric current start compressor by start winding group,
then the relay resistance is increased and electric current is decreased, only tiny
electric current flows relay, which make the relay keep high resistance.
This relay is called PTC relay, the resistance will be increased with the temperature
raise.
Can use the Ohmmeter to check this solid relay. Under the room temperature
condition, the relay resistance should be 10% regular range of refrigerator electric
diagram request.
11
Page 13
7-4 Temperature Controller
Compressor operation is controlled by temperature controller, the temperature
controller is mainly consist of capillary, corrugated pipe, a group of closed junction and
a mechanical link.
The gas pressure in the capillary and corrugated pipe is controlled by
temperature sensor pipe, the temperature raise will cause the corrugated pipe
to push the link and close the junction.
When the temperature is dropped, the corrugated pipe will be shrinked to
push the link and open the junction.
Connect the probe of Ohmmeter with the temperature controller and turn ON
and OFF to check the junction .
