The capacitor could be bad. A tripped circuit breaker is possible. Check the thermostat setting first. Ensure it is set to cool.
Compressor Running Constantly
Your compressor never stops. The fridge is too cold. It might be running too much. This wastes energy. The door seals could be worn. They let warm air enter. The condenser coils might be dirty. This makes the compressor work harder. The thermostat could be malfunctioning. It might not signal the compressor to stop.
Compressor Making Strange Noises
Hear odd sounds? The compressor could be failing. Humming is normal. Loud buzzing is not. Rattling sounds mean trouble. Clicking noises are concerning. These indicate internal damage. It might need replacement soon. A loose mounting bolt is a cause. Internal wear is another reason.
Compressor Overheating
The compressor feels very hot. This is a serious sign. It can damage the unit. Dirty condenser coils are a cause. Poor ventilation is another. The compressor may be overworked. Low refrigerant levels cause strain. A failing start relay can lead to this. Overheating can cause a shutdown. It may prevent cooling altogether.
Diagnostic Steps

When your refrigerator stops cooling, the compressor might be the culprit. Troubleshooting it yourself can save time and money. These diagnostic steps help pinpoint the problem. Follow them carefully.Check Power Supply
First, ensure your fridge gets power. Is it plugged in? Check the outlet. Use a voltage tester. The outlet should have power. No power means a different issue.Inspect The Relay And Overload Protector
These parts protect the compressor. They are usually near the compressor. Look for burnt wires. A faulty relay stops the compressor. The overload protector might trip. Reset it if possible.Test The Start Capacitor
The start capacitor helps the compressor begin. It looks like a small cylinder. A multimeter tests it. Check for continuity. A bad capacitor prevents starting.Listen For Humming
Turn on the refrigerator. Listen closely. Do you hear a hum? A faint hum is good. No sound suggests no power. A loud hum is bad. It might mean the compressor is stuck.Measure Voltage And Amperage
This requires a multimeter. Measure the voltage at the compressor. Check the amperage draw. Compare readings to specifications. Low voltage or high amperage signals trouble. This confirms compressor failure.
