Why is my VAT PLUTO cooling insufficiently?
If your VAT Refrigerator is on but cooling is insufficient, it could be because the ambient temperature exceeds the maximum operating temperature (43°C/110F). Choose a colder location, such as a shaded area.
Why is the condenser fan not working on my VAT Refrigerator?
If the condenser fan of your VAT Refrigerator is not working, it may be due to bad connections or a defective relay, fuse, fan switch, or fan motor. Check to ensure the condenser fan is not faulty and that the connections to the wiring harness are secure at the plugs.
What causes high suction pressure in my VAT Refrigerator?
If your VAT Refrigerator is experiencing high suction pressure, it may be due to a defective compressor or expansion valve, or an open hot gas valve. Check the TXV (thermostatic expansion valve) inside the evaporator box.
What causes low discharge pressure in my VAT PLUTO?
If your VAT Refrigerator is experiencing low discharge pressure, it could be due to a defective compressor, low refrigerant charge, or an open hot gas valve. Check that the sight glass is full and not showing bubbles.
What causes low suction pressure in my VAT PLUTO?
If your VAT Refrigerator is experiencing low suction pressure, it could be due to low evaporator airflow, low refrigerant charge, or a defective TXV. Check that the evaporator core is not plugged by dirt, frost, or a block of ice.
How to fix a VAT Refrigerator when the defrost is not working?
If the defrost is not working on your VAT Refrigerator, it might be due to incorrect defrost setting parameters. Check the automatic defrost setting or run defrost manually.
What causes high discharge pressure in my VAT PLUTO Refrigerator?
If your VAT Refrigerator has high discharge pressure, it may be caused by refrigerant overcharge or condenser malfunction. Check that the condenser fan is on and the air flow is sufficient.
What to do if my VAT PLUTO does not start?
If your VAT Refrigerator is not starting, it could be due to no power reaching the controller. Check the controller connection to the wiring harness at the controller plug.
Why is my VAT PLUTO Refrigerator blowing warm air?
If your VAT Refrigerator is on but blowing warm air, the compressor may not be starting or could be defective. Check the compressor connection on the signal wire plug.
What to do if the evaporator fan is off on my VAT Refrigerator?
If your VAT Refrigerator is on but the evaporator fan is off, it could be due to no power or wake-up signal reaching the evaporator fan. Check that the evaporator fan is not faulty and that the connections to the wiring harness are secure at the plugs.
