IV. FUNCTIONS
4.1.4
As a reference to determine the causes of
trouble, malfunction and phenomena are
described below. Refer to the following
when repairing.
i. Disconnection of defrost heater
As off-cycle defrosting is performed, the
defrosting time is extremely prolonged.
Each time defrosting is started, the
freezer temperature rises and a portion
of ice and stored foods are melted.
ii. Melted thermo fuse or opened-circuit
due to the defect of defrost thermostat
.
When the above mentioned trouble
occurs in cooling operation, the timer
motor does not run, defrosting will not
take place, and consequently freezing is
caused. In the above mentioned
condition, when the time shaft is turned
by hand to defrost, the timer motor runs
during the operation time. However, the
motor stops from the time wien the
contact is changed, and freezing
causes.
Note :
As the thermo fuse assembly is
intended to prevent dangers, do not use
it under shorted condition even for a
short period.
4.2
DEW PREVENTION

i.

by hand while the compressor is in operation.
ii.
If you are asked about this, please explain that
the hot pipe serve to prevent the dew
generation.
