Why Is the Fridge Not Cold But the Freezer Is?

Published in Appliance Troubleshooting 2 mins read

The fridge and freezer compartments in your refrigerator have separate cooling systems. The freezer compartment is designed to maintain a much colder temperature than the fridge, which allows it to freeze food.

How Refrigeration Works

Refrigerators and freezers use a refrigerant to cool the air inside. The refrigerant circulates through a closed loop system, and its state changes between liquid and gas.

  • Evaporation: As the refrigerant evaporates, it absorbs heat from the air inside the fridge or freezer. This cools the air.
  • Condensation: The refrigerant then flows to the condenser, where it releases the absorbed heat and condenses back into a liquid.
  • Expansion: The liquid refrigerant is then expanded, which lowers its temperature, and the cycle repeats.

Temperature Differences

  • Freezer: The freezer compartment has a separate cooling system that uses a lower temperature setting for the refrigerant. This allows the freezer to maintain a temperature below 0°F (-18°C), freezing food.
  • Refrigerator: The fridge compartment has a separate cooling system that uses a higher temperature setting for the refrigerant. This keeps the fridge cool enough to store food at a temperature above freezing but not cold enough to freeze it.

Common Issues

If your fridge is not cold but the freezer is, it could be due to a few reasons:

  • Faulty thermostat: The thermostat in the fridge compartment may be malfunctioning, preventing it from cooling properly.
  • Blocked airflow: The airflow around the condenser coils may be blocked, preventing the refrigerant from releasing heat effectively.
  • Refrigerant leak: A refrigerant leak can cause the fridge to lose its cooling capacity.

Solutions

  • Check the thermostat: Ensure the thermostat is set to the desired temperature and is functioning properly.
  • Clean the condenser coils: Regularly clean the condenser coils to ensure proper airflow.
  • Contact a technician: If the problem persists, contact a qualified refrigerator technician for diagnosis and repair.
