A fridge that's running but not cooling is one of the most stressful appliance problems. Your food is at risk of spoiling, and you need a quick solution. Before you panic, understanding the possible causes can help you communicate the issue better. Here are the 10 most common reasons your fridge is not cooling and how to fix them.
1. Low Refrigerant Gas
This is the most common cause of fridge not cooling. Refrigerant gas absorbs heat from the fridge interior and releases it outside. Gas leaks can develop over time due to corrosion or manufacturing defects.
Symptoms: Fridge running but not cold, compressor running continuously, hissing sound, frost buildup on the evaporator in small patches.
Solution: Professional gas leak detection and refilling by Home Fixer. We identify and fix all leaks before refilling with the correct type and amount of gas.
2. Dirty Condenser Coils
Condenser coils at the back or bottom of the fridge release heat. When covered in dust, they can't dissipate heat efficiently.
Symptoms: Fridge not cooling properly, compressor running more than usual, higher electricity bills.
Solution: Clean the condenser coils with a brush or vacuum. Home Fixer includes coil cleaning in every annual maintenance service.
3. Faulty Thermostat
The thermostat controls the temperature inside the fridge. If it's malfunctioning, the compressor may not turn on when needed.
Symptoms: Fridge too warm or too cold, temperature fluctuating, compressor not running.
Solution: Thermostat testing and replacement. Home Fixer provides genuine thermostat replacement for all fridge brands.
4. Compressor Issues
The compressor is the heart of the refrigeration system. If it's failing, the fridge won't cool properly.
Symptoms: Warm fridge, clicking sound from the back, compressor very hot to touch, compressor not starting.
Solution: Professional compressor diagnosis. Home Fixer technicians can repair or replace compressors same-day.
5. Blocked Air Vents
Frost-free refrigerators use air vents to circulate cold air. If vents are blocked by food items or ice buildup, cooling is affected.
Symptoms: Some areas of the fridge are cold while others are warm, uneven cooling.
Solution: Rearrange food items to ensure vents are not blocked. If ice is blocking vents, defrost the fridge and check for defrost system issues.
6. Faulty Evaporator Fan
The evaporator fan circulates cold air inside the fridge. If it stops working, cold air won't reach the fridge compartment.
Symptoms: Freezer works fine but fridge is warm, no air circulation sound inside the fridge.
Solution: Evaporator fan motor replacement. Home Fixer carries fan motors for all major brands.
7. Defrost System Failure
Frost-free fridges have automatic defrost systems. If the defrost timer, heater, or thermostat fails, ice builds up on the evaporator coils and blocks cold air circulation.
Symptoms: Thick frost buildup on back wall, fridge getting progressively warmer over days.
Solution: Defrost system diagnosis and repair. Home Fixer technicians test all defrost components and replace faulty ones.
8. Damaged Door Gasket
A worn or torn door seal allows cold air to escape, making the fridge work harder without cooling properly.
Symptoms: Fridge runs constantly but doesn't cool, visible gaps in the door seal, condensation on the outside.
Solution: Door gasket replacement with genuine OEM seals. Home Fixer stocks seals for all popular fridge models.
9. Overloading the Fridge
Overcrowding prevents proper air circulation, leading to uneven cooling and warm spots.
Solution: Remove some items and ensure there's space between items for air to circulate. Don't block air vents with food.
10. Voltage Fluctuations
Delhi's frequent voltage fluctuations can damage the compressor start relay or overload protector, preventing the compressor from starting.
Solution: Install a voltage stabilizer for your fridge. Check the start relay and overload protector. Home Fixer replaces these components at affordable rates.
