Refrigerator Not Cooling But Light Is On: How to Fix Fast

When your fridge cabinet gets warm while internal lights stay lit, it points directly to dirty condenser coils, a faulty starter relay, or a defective defrost timer.

1. Clean Dust from Condenser Coils

Dust buildup prevents heat dissipation, forcing the compressor to shut down defensively.

2. Listen for Compressor Clicking

A repeated click every 2-3 minutes indicates a bad start relay that needs immediate replacement.

💡 Master Engineer Safety Tip

Never attempt to bypass safety door switches, pressure sensors, or work on live electrical components without isolating the main power supply. If an error code persists after basic filter cleaning, call a certified technician immediately to prevent damaging the main PCB control board.
