Dirty evaporator coils:
The evaporator coils are responsible for cooling the air inside the maria machine. If these coils are dirty, it can restrict airflow and reduce the efficiency of the machine. To clean the evaporator coils, turn off the machine and unplug it. Then, remove the front cover of the machine and use a soft cloth to gently wipe the coils clean.
Low refrigerant level:
The refrigerant is a chemical that circulates through the machine and helps to cool the air. If there is a low refrigerant level, the machine will not be able to freeze up as quickly or effectively. To check the refrigerant level, contact a qualified technician.
Damaged compressor:
The compressor is the part of the machine that compresses the refrigerant and circulates it through the system. If the compressor is damaged, it will not be able to properly circulate the refrigerant and the machine will not freeze up. To check the compressor, contact a qualified technician.
Overloaded van:
If you are carrying a heavy load of ice cream in your van, it may be putting a strain on the maria machine and causing it to work harder than it needs to. This can lead to the machine freezing up more slowly and feeling heavy. Try to keep your van's load as light as possible, especially if you are traveling in hot weather.
If you have tried all of these things and the machine is still not freezing up properly or feeling heavy, you may need to contact a qualified technician for help.
