How to troubleshoot a short circuit in the air temperature sensor of my VAT Refrigerator?
To troubleshoot a short circuit in the air temperature sensor of your VAT Refrigerator, check the air temperature sensor resistance, plug, and continuity to the controller.
Why is the evaporator iced up in my VAT PLUTO Refrigerator?
If your VAT Refrigerator's evaporator is iced up, it may be due to a needed defrost, a plugged drain, or insufficient airflow. Inspect the evaporator condensation drain to ensure it is not blocked by dirt or a kinked hose.
What to do if my VAT PLUTO has high discharge pressure?
If your VAT Refrigerator is experiencing high discharge pressure (higher than 240 psi), ensure that the condenser fan is functioning and that the airflow is sufficient. Also, verify that the condenser coil is free from dirt and debris. Finally, check the high-pressure switch and its continuity to the controller.
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.
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.
How to troubleshoot a short circuit in the defrost temperature sensor of my VAT PLUTO Refrigerator?
To troubleshoot a short circuit in the defrost (evaporator) temperature sensor of your VAT Refrigerator, check the evaporator temperature sensor resistance, plug, and continuity to the controller.
How to troubleshoot a short circuit in the ambient temperature sensor of my VAT PLUTO Refrigerator?
To troubleshoot a short circuit in the ambient temperature sensor of your VAT Refrigerator, check the ambient temperature sensor resistance, plug, and continuity to the controller.
How to troubleshoot an open circuit in the defrost temperature sensor of my VAT PLUTO Refrigerator?
To troubleshoot an open circuit in the defrost (evaporator) temperature sensor of your VAT Refrigerator, check the evaporator temperature sensor resistance, plug, and continuity to the controller.
Why is my VAT Refrigerator leaking water from the evaporator?
If your VAT Refrigerator is leaking water or splashing from the evaporator, it could be due to a plugged drain or a slanted evaporator pan. Check if the vehicle is parked on a slope, preventing water from draining from the evaporator pan.
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.
