DEEP-FREEZER AND STORAGE RANGE
page 31 out of 37
Insufficient defrosting
Bad technical parameters of the
regulator.
See above To launch a
manual defrosting.
Temperature end of defrosting
too high (parameter
Temperature defrost.).
Check the parameter while
checking the card.
If necessary, increase the
temperature gradually.
The hours of programmed
defrosting are not in an
ascending order.
Reprogram hours of
defrosting in an ascending
order ex: 02h00, 10h00,
18h00.
Intensive use of deep-freezing
Add an automatic defrost
with the parameter
Number of defrosts.
One of the resistances does not
heat.
Control of connections.
Change resistance.
Evaporator’s tube for
water flow is blocked
Blocking by foreign bodies
Clean including the
siphon.
Ice
Check the operation of the
flow’s resistance
Test the corresponding
circuit.
Change the latter if it is
defective
The deep-freezing shitter
does not close
The servo-motor stopped and is
disconnected
Check the proper
movement of the shutter.
The servo-motor does not work
Test the corresponding
circuit of control.
Change the component
with default
Presence of bubbles in
the liquid indicator..
Liquid circuit partially blocked
between the tank and the liquid
indicator.
Control the components
placed on the circuit.
Replace the components
with default
Lack of refrigerating liquid.
Find the leak.
Repair the leak.
Make the complement of
load.
No circulation with the
liquid indicator
Circuit blocked
Check that all components
placed on the circuit are
open and not blocked.
Open, unblock or replace.
Installation completely emptied
of refrigerant liquid.
Find the leak
Repair the leak or change
the piece with default
Change the dehydrator.
Empty completely all the
installation
Re-do the Fréon charging
Evaporator insufficiently
filled or overheating a lot
Presence of bubbles to the liquid
indicator
See above.
Regulator set incorrectly.
Operate the adjustment
by decreasing
overheating.
Regulator partially blocked
Clean expansion valve
Overheating condenser
Circulation of air partially
blocked.
Ensure the free flow of air
around the condenser.
Clean the condensor.
Presence of incondensable in
the refrigerating circuit.
Check the leaks.
Remove the refrigerating
load of the circuit.
Change the dehydrator.
Empty the installation and
reload it afterwards.
Condensation around the
doors.
The doors heaters do not heat
Check power.
Control the proper
operation of each cord.
