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
