Why Your Fridge Isn’t Cooling (And When to Call a Technician)
A Quick Story from Guelph
Last week, a homeowner on Raymond Street called us in a panic — her fridge light was on, but everything inside was warm. She thought it meant buying a new refrigerator.
After a quick inspection, we found the culprit: a dirty condenser coil and a faulty temperature sensor. A 30-minute fix saved her nearly $1,500 on a replacement.
If your fridge seems warm but still running, don’t rush to replace it. The problem may be simpler than it looks.
Common Reasons Your Fridge Stops Cooling
Dirty Condenser Coils
Dust and pet hair can block airflow, forcing your fridge to work harder. Cleaning the coils twice a year prevents overheating and cooling issues.
Faulty Evaporator Fan Motor
This fan circulates cold air inside the fridge. If it stops spinning, the temperature inside will rise quickly.
Defective Temperature Sensor (Thermistor)
When this sensor fails, your fridge cannot measure the temperature correctly, causing uneven cooling or complete shutdown.
Clogged Air Vents
Overpacking your fridge blocks air circulation. Leave space between items so cold air can move freely.
Compressor or Start Relay Problems
If you hear repeated clicking but no humming, your compressor may not be running. This requires a professional technician to inspect.
When to Call a Technician
If you have already checked the power, cleaned the coils, and made sure the vents are clear, but your fridge is still warm, the problem might be electrical or refrigerant-related.
That’s the time to contact a certified technician.

Frequently Asked Questions
Q: My fridge light is on but it’s not cold. What should I check first?
Unplug the fridge for five minutes and plug it back in. Listen for the compressor hum. If you only hear a click and no humming, the compressor relay or motor may be faulty.
Q: Can I use a hairdryer to defrost faster?
A: You can, but be cautious. Too much heat can damage plastic parts. If frost builds up again soon after, the defrost heater or thermostat may have failed.
Q: Is it worth repairing an old refrigerator?
A: If your fridge is under ten years old, a repair is often more economical. Most common issues, such as fans or sensors, cost less than $300 to fix.
Local Insight
Many older Guelph homes have limited kitchen ventilation, which can cause fridges to overheat more easily. Leave a few inches of space behind and beside the appliance for better airflow and cooling performance.
