Why Your Refrigerator May Stop Cooling
A refrigerator that stops cooling is a household emergency — food spoils within hours in Delhi's heat. The good news is that many cooling problems have simple fixes. Before you panic, let's diagnose the issue. At Medon Company, our technicians handle fridge repairs across South Delhi, Vasant Kunj, and Mahipalpur daily.
8 Common Reasons Your Fridge Is Not Cooling
Here are the most frequent causes, ordered from simplest to most complex:
1. Temperature Settings Changed Accidentally
Check your fridge's temperature dial or digital display. Someone may have accidentally bumped it to a warmer setting. Set it to 3–5°C for the fridge compartment and -18°C for the freezer. Wait 24 hours after adjusting before concluding there's a problem.
2. Dirty Condenser Coils
Condenser coils (usually at the back or bottom of the fridge) release heat. When covered in dust, they can't dissipate heat efficiently, causing poor cooling. Clean them every 6 months with a vacuum brush attachment. This is especially important in Delhi's dusty environment.
3. Damaged Door Seal (Gasket)
A worn or damaged door seal lets warm air leak into the fridge, forcing it to work harder. Test by closing the door on a piece of paper — if the paper slides out easily, the seal needs replacement. Door seal replacement costs ₹399–₹799 and takes 30 minutes.
4. Overstocked or Blocked Vents
Stuffing your fridge blocks the air circulation vents between the freezer and fridge compartments. Cold air can't flow properly, causing uneven or poor cooling. Leave some space between items and never block the rear vent panel.
5. Faulty Thermostat
The thermostat controls when the compressor turns on and off. A faulty thermostat may not signal the compressor to run, resulting in no cooling. This is a common issue in refrigerators older than 5 years. Replacement costs ₹499–₹999.
6. Low Refrigerant (Gas Leak)
Like ACs, refrigerators also use refrigerant gas for cooling. A gas leak causes gradual cooling decline. Signs include the compressor running continuously, frost in unusual places, or the back panel feeling unusually warm. Professional refrigerator gas refilling costs ₹999–₹1,999.
7. Faulty Evaporator Fan
The evaporator fan circulates cold air from the freezer to the fridge. If it fails, the freezer may cool fine but the fridge won't. Listen for the fan — if you don't hear it running when the door is closed (press the door switch), it may need replacement.
8. Compressor Failure
The compressor is the most critical (and expensive) component. If it fails, the fridge won't cool at all. Signs include a clicking sound, the compressor getting very hot, or no humming sound at all. Compressor repair or replacement costs ₹2,000–₹8,000 depending on the model.

Quick Troubleshooting Steps
Try these before calling a technician: (1) Check and adjust the temperature setting. (2) Ensure the fridge isn't overstocked. (3) Clean the condenser coils. (4) Check the door seal. (5) Verify the power supply is stable. (6) Listen for unusual sounds. If basic troubleshooting doesn't help, Medon's verified technicians in Delhi can diagnose the exact issue starting from just ₹199.
When to Repair vs. Replace Your Refrigerator
A common dilemma! Here's a practical guideline: If your fridge is less than 7 years old and the repair cost is under 40% of a new fridge's price, repair is the better option. For fridges older than 10 years with major issues (compressor failure), replacement is usually more cost-effective considering improved energy efficiency of newer models. Our technicians always provide honest advice — we won't recommend unnecessary repairs.
