Common causes of a refrigerator compressor overheating

  • Dust accumulation: A clogged condenser coil traps heat, forcing the compressor to work harder. Regular cleaning prevents this issue.
  • Inadequate ventilation: Placing the fridge too close to walls restricts airflow, leading to overheating. Ensure there is enough space for ventilation.
  • Refrigerant issues: Low or leaking refrigerant makes the compressor overwork, causing excessive heat buildup. A professional check is recommended.
  • Overloaded fridge: Overstuffing blocks airflow, making the compressor work harder. Organising storage helps maintain optimal cooling.
  • Thermostat problems: A faulty thermostat can prevent the fridge from regulating temperature correctly, increasing compressor strain.

Step-by-step guide to fix an overheating compressor

  • Check the power supply: Ensure that the fridge is plugged in properly and the voltage is stable.
  • Clean the condenser coils: Dust buildup can trap heat, so use a vacuum or coil brush to clean them.
  • Ensure proper ventilation: Move the fridge away from the walls to improve airflow around the compressor.
  • Inspect the door seals: A faulty seal lets cold air escape, forcing the compressor to work harder. Replace damaged gaskets if necessary.
  • Check the refrigerant levels: Low refrigerant can overwork the compressor. A professional technician should handle refills and leak repairs.
  • Reduce fridge load: Avoid overpacking the fridge to maintain smooth airflow and reduce strain on the compressor.
  • Reset the fridge: Unplug the appliance for a few minutes, then plug it back in to help the system stabilise.

Preventive measures to keep your refrigerator compressor cool

  • Clean condenser coils regularly: Dust buildup traps heat, making the compressor overheat. Clean at least twice a year.
  • Ensure proper spacing: Maintain at least 2-3 inches of space around the fridge for ventilation.
  • Monitor temperature settings: Set the fridge at the recommended 3-5°C and the freezer at -18°C to avoid overworking the compressor.
  • Check the door seals: Inspect and replace damaged gaskets to prevent cold air leakage.
  • Avoid overloading: Proper air circulation inside the refrigerators reduces strain on the cooling system.
