Why Your Refrigerator Is Not Cooling — and What to Check First
A warm fridge is one of the most common appliance complaints. Before you call for a repair, these five checks take two minutes each and often reveal the cause — or at least rule out the simple stuff.
Check the thermostat setting
It sounds obvious, but the dial or digital setting sometimes gets bumped while cleaning. Set it to mid-range (around 4°C) and wait 24 hours. If it's a digital model, check for a 'demo' or 'showroom' mode — it runs the lights but not the compressor.
Clean the condenser coils
Dusty condenser coils (the metal grid at the back or underneath) can't release heat, so the fridge struggles to cool. Unplug the fridge, brush or vacuum the coils, and give it an hour. This single step restores cooling in many older single-door fridges.
Inspect the door seals
A torn or loose rubber gasket lets cold air escape. Close the door on a ₹100 note — if you can pull it out easily, the seal is weak. Wipe the seal with warm soapy water; if it's torn or warped, it's a ₹400 replacement that fixes the problem.
Listen to the compressor
Put your ear near the back. A healthy compressor is a steady low hum. Click-click-click with no start, or a loud knock, means the start relay or the compressor itself has failed. If the compressor is silent and the back is cool, the thermostat or defrost timer is the likely culprit.
When to call a technician
If all four checks pass and the fridge still won't cool below 10°C, the fault is internal — capillary blockage, refrigerant leak, or a failed component. That's when you need a manifold gauge and clamp meter. Book a ₹599 doorstep diagnosis and we'll tell you exactly what's wrong before you spend on parts.
