4.
If the compressor is observed to be running
continuously but no cooling is attained - this may be
due to leakage of refrigerant gas from the system or
defect in the unit, - Notify Refrigerator Technician.
5.
Check if the compressor tries to start but trips-off early
by the over-load protector. This may be either due to
too low supply voltage or defect in the compressor or
starting relay - put `off' the ILR till return of normal
voltage and try to run once again. If the defect
prevails, - Notify Refrigerator Technician.
C) CABINET TEMPERATURE IS
LOWER THAN NORMAL OR BELOW
0°C WHEN FUNCTIONING AS
`REFRIGERATOR'.
Turn the thermostat knob, anti-clockwise, to a lower
setting (see page 14, action 7B) and observe if the
compressor is cut `off' by the thermostat. If the same
does not cut `off' even at the lowest (1 ) setting, the
thermostat may be defective and may have to be
replaced - Notify Refrigerator Technician.
NOTE:
In such cases, till the repair is done, the vaccines
should be preserved as follows
a) Take out the floors and the layer of ice packs
b) Put one layer of fresh (non-frozen) ice packs o n
the bottom and replace the floors
c) Keep some not-frozen ice packs on and around the
vaccines also
d) Run the ILR under surveillance and put it `off'
when lowest recommended temperature is
attained. Put the ILR `on' again when the highest
recommended temperature is reached and keep
it running until the lowest recommended
temperature is attained again. Repeat as above
till the ILR is repaired.
D) ABNORMAL NOISE IN THE ILR
In case of any abnormal noise coming out from the
ILR, try to locate the source of the noise. Generally
it may come from the compressor compartment. In
such cases,
1. Take out the plug of the ILR from socket and
open the side cover of the compressor
compartment (see page 5, actions 1 )
2. Examine if the mounting brackets of the
compressor are in place and secure, and if the
mounting bolts for the fan are tight. If required
replace broken or lost brackets and tighten loose
bolts (see page 6 & 7, fig. 4 & 7)
3. Check if any pipe or component has come out of
its position and also touching others. If so, rectify
carefully.
4. Check if the ILR is level and firm on its base. If
not, rectify.
5. Even after actions as above if it is observed that
the noise is still present or it is coming from the
inside of the compressor - Notify Refrigerator
Technician.
