Refrigerator Compressor Clicks But Won't Start? Here's the Fix
Hearing a clicking sound from your fridge but it won't cool? Learn why a faulty PTC start relay or overload protector is likely the cause and how to fix it.
Introduction to the Problem
You plug in your fridge, hear a single "click" from the back, and then silence. The fridge doesn't cool.
In this guide, we cover Why Your Fridge Compressor Clicks But Won't Start. At Prime Cool, our expert technicians resolve this specific issue every single day across Pune.
Key Causes in 2026-2027
- Failed PTC Start Relay: The most common culprit. The relay fails to provide the initial voltage boost to start the compressor, causing the overload protector to trip (the click).
- Faulty Capacitor: The start or run capacitor has degraded.
- Seized Compressor: The mechanical pump inside the compressor has locked up (worst-case scenario).
Expert Troubleshooting
Do not bypass the overload protector to force a start; this can cause an electrical fire. A relay replacement is a cheap, 10-minute fix for a professional.
Stop wasting food. Book a rapid refrigerator repair with Prime Cool and our technicians will replace the relay on the spot.
