  If the compressor 1st stage commutes (on-off-on-off), the compressor 2nd stage is off, and the ventilator functions in your FIOCCHETTI Freezer, several issues could be the cause. It might be due to a defective magnet switch for water. Another potential cause is constipation of the warmth exchanger. Additionally, check if the water temperature is too high, the water pressure is too low, or if there is an absence of water circulation.

  If the compressor 1st stage commutes (on-off-on-off), the compressor 2nd stage is off, and the fan does not operate in your FIOCCHETTI Freezer, you should first check the voltage at the fan outlet. Also, check the fan itself to ensure it is functioning correctly.

  If the compressor 1st stage, fan, and compressor 2nd stage are operating in your FIOCCHETTI Freezer, check for a leakage in the 1st stage. Also measure the refrigerant in the 2nd stage. Finally, check if the 2nd stage is choked up by moisture or oil.
