A serious issue with fridge freezers is the failure to maintain the correct temperature

A serious issue with fridge freezers is the failure to maintain the correct temperature, leading to spoiled food and potential health risks. This problem can arise from several causes, including faulty thermostats, compressor issues, dirty condenser coils, or improper door seals. Here’s a comprehensive guide on how to address this issue:

Causes and Solutions for Temperature Problems

  1. Faulty Thermostat

Cause: The thermostat regulates the temperature inside the fridge and freezer compartments. If it malfunctions, the appliance may not cool properly.


  • Test the Thermostat: Set the thermostat to a colder setting and listen for a click, indicating it’s working. If there’s no click, it might be faulty.
  • Replace the Thermostat: Unplug the fridge, locate the thermostat (usually behind a panel inside the fridge), and replace it with a new one following the manufacturer’s instructions.
  1. Compressor Issues

Cause: The compressor is essential for cooling. If it fails, the fridge freezer won’t maintain the correct temperature.


  • Listen for Compressor Noise: A humming noise usually indicates the compressor is working. If it’s silent or making strange noises, it could be failing.
  • Professional Repair: Compressor issues often require professional diagnosis and repair or replacement, as they involve refrigerant handling and complex components.
  1. Dirty Condenser Coils

Cause: Condenser coils release heat from the fridge. If they are dirty or dusty, they can’t dissipate heat efficiently, leading to cooling problems.


  • Locate and Clean the Coils: Unplug the fridge and locate the condenser coils, typically at the back or underneath. Use a vacuum or coil brush to remove dust and debris.
  • Regular Maintenance: Clean the coils every six months to ensure efficient operation.
  1. Improper Door Seals

Cause: Door seals (gaskets) prevent warm air from entering the fridge and freezer. If they are damaged or not sealing properly, the appliance will struggle to maintain temperature.


  • Inspect the Seals: Check for cracks, tears, or gaps in the door seals. Close a dollar bill in the door; if it slides out easily, the seal might be faulty.
  • Replace or Repair Seals: If damaged, replace the seals. For minor issues, clean the seals with warm, soapy water and ensure they are properly aligned.
  1. Blocked Air Vents

Cause: Air vents circulate cold air between the fridge and freezer compartments. If blocked by food items, air circulation is hindered, affecting temperature.


  • Check and Clear Vents: Locate the air vents inside the fridge and freezer. Ensure they are not obstructed by food packages or other items.
  • Organize Contents: Keep food organized and ensure vents are clear to maintain proper airflow.


Maintaining the correct temperature in a fridge freezer is crucial for food safety and appliance efficiency. Regular maintenance, such as cleaning condenser coils, checking door seals, and ensuring proper air circulation, can prevent temperature issues. Addressing thermostat or compressor problems promptly can also prevent more serious failures. If DIY solutions don’t resolve the problem, consulting a professional technician for more complex repairs is advisable to ensure the appliance operates correctly and safely.
