SOLUTION
Replace the ventilators/fans.
Replace the thermostat/electronic control board.
If the electronic control board is used on appliances with R290
coolant, it must only be replaced with an original spare part
supplied by the manufacturer. Replace the temperature probes
only after having ascertained which of them is inefficient.
Clean the condensing unit thoroughly.
The condensing unit in particular operating environments
(e.g. presence of dust, presence of excessive humidity, etc.)
when the performance of the appliance deteriorates requires
careful cleaning.
Find the cause of the refrigerant loss and remove it;
top up the refrigerant load if necessary having emptied
the system.
Check the reasons why the pressure switch is operating at
maximum pressure levels, such as: air condenser obstructed,
condenser fan with air stopped, ambient temperature too
high, pressure switch defective.
