DEFECT
PROBABLE CAUSES
POSSIBLE REMEDIES
The compressor works constantly
or for too long periods
The temperature inside the room is too
high
The compressor can only work constantly if there is no chance of decreasing
room temperature (for instance with a.c. system)
The temperature of the compressors’ room
is too high (remote comp.)
See above
The air condenser is blocked
Clean the condenser carefully
Cooling air flow of the water condenser is
not sufficient
Check the efficiency of the regulation valve and make sure that taps are
turned on
Lack of refrigerant
Identify the eventual leak and refill with refrigerant
Internal ventilation is not sufficient
Restore a proper ventilation by replacing the faulty fans or by removing the
eventual obstacle
Evaporators are extremely clogged
Operate a complete defrost cycle
The temperature set on the thermostat is
too low
Adjust temperature settings
Temperature is not displayed on
the digital panel
Flat battery
Replace battery
Sensor does not work properly
Replace digital thermostat
Faulty electronics
Replace digital thermostat
Defrost water missing
Water drain pipes are blocked
Remove the obstacle
Defrost cycle is not efficient
Verify the efficiency of control panel (slave module, sensor, solenoid valve..)
and the position of the end cycle sensor
Lighting is not working
The switch is off
Turn the switch on
The neon lamp is not properly fitted in its
case
Ad just the lamp by rolling it
Exhausted lamp
Replace the lamp
Ballasts or starter are not efficient
Replace faulty components
The unit is too noisy
Vibrations of internal plates
Tighten all the fixing screws
Internal fans are not fixed well
See above
Fans’ blades are not fixed well
Replace faulty fans. If there is friction between the blades and some ice
formation, then act on defrost cycle settings
Pipes are in contact with other parts of
equipment
Avoid any contact between pipes and other parts; a constant rubbing might
wear the pipes out and give way to refrigerant leaking
The unit is not well levelled
Adjust the levelling
Condensation water forming on the
glasses
Transformer is not working
Check that the transformer is correctly supplied - Verify the correct
functioning of the transformer fuse - Replace the transformer
Heating circuit interrupted
Replace the glasses
