📝 Step-by-Step Instructions
Safety first: Unplug your Refrigerator from the main power socket before performing any physical inspection.
Clean the condenser coils at the back or bottom — dust buildup is the #1 cause of poor cooling.
Check the door gasket by placing a paper between the door and frame — it should resist when pulled.
Listen for a click when the fridge tries to start — a clicking sound often means a failed start relay (cheap fix).
Ensure the temperature dial is set between 3–4 for fridge and -18°C for freezer.
Check that the fridge is not overpacked — blocked airflow reduces cooling.
Based on the symptom (Not Cooling), common root causes include: Low or no refrigerant; Faulty compressor; Dirty condenser coils. This will guide your inspection.
After performing these checks, reconnect power and test the Refrigerator through a full cycle.
If the problem persists, avoid further DIY. Continued operation with a hardware fault can cause secondary damage.
