Frequently Asked Questions (15)

• What should I do if my Panasonic NR-B53V1 refrigerator is not cooling properly?

  If your refrigerator is not cooling properly, check the following:

  1. Self-Diagnosis Code: Check if a Self-Diagnosis code or its history appears on the display panel. Press the "set button" for more than 10 seconds to check.
     • If a code appears, refer to the Troubleshooting Guide for specific actions related to that code (e.g., H12 for PEC sensor, H02 for PCC sensor, H27/H28 for fan issues, H32 for defrost heater, H34 for 3-Way Valve).
  2. Food Placement: Check if there is food influencing the perception temperature near the PCC sensor. If so, move the food.
  3. Door Closure: Ensure the PC Door is not slightly opening. If it is, replace or correct the Gasket Door PC.
  4. Frequent Door Opening: If the PC Door is opened frequently, this can affect cooling.
  5. Hot Food in PC: Avoid placing hot food in the PC compartment.
  6. Ambient Temperature: Check the ambient temperature as excessive cooling can occur if the ambient temperature is 5°C or below.
  7. 3-Way Valve: Check the resistance between terminals of the 3-Way Valve (should be 2.2 kΩ ± 0.2 kΩ). Issues here could indicate a faulty valve or energizing problems.
