Understanding Refrigerator Cooling Issues
A refrigerator that stops cooling can spoil expensive food items quickly. Here are the top reasons why cooling drops and what you can do about it.
1. Dirty Condenser Coils
Dust accumulation on rear or bottom condenser coils prevents heat dissipation. Vacuum clean coils twice a year.
2. Faulty Defrost Timer or Heater
In frost-free fridges, a broken defrost timer causes ice build-up over the evaporator coils, blocking airflow into the fridge compartment.
3. Low Gas (Refrigerant) Level
Gas leakages caused by pinholes in copper piping lead to continuous compressor running with zero cooling. Professional gas charging is required.
