A fridge that suddenly stops cooling is stressful — especially if it's full of food. Before rushing to call a technician, there are a few things worth checking yourself first.
Check these simple things first: make sure the fridge is actually plugged in and the outlet works, check the temperature setting (it may have accidentally been bumped to the lowest setting), and make sure the door can close tightly (a worn door seal lets cold air leak out).
If the fridge is running (interior light on, compressor sound audible) but still not cooling, the issue is likely with refrigerant circulation or a dirty condenser — the back of the fridge, rarely cleaned, can accumulate thick dust that blocks heat dissipation.
Signs that mean you MUST call a technician immediately (don't attempt to open it yourself):
— A strong gas/chemical smell from the back of the fridge (indicating a refrigerant leak, harmful if inhaled repeatedly).
— The compressor makes no sound or vibration at all despite normal power.
— Unusually thick frost buildup in the freezer even after defrosting.
Delaying service on a malfunctioning fridge risks wasted food and can worsen component damage — the sooner a technician checks it, the smaller the chance you'll need an expensive part like a new compressor.
