A refrigerator that runs but isn’t cold is most often caused by a dirty condenser coil, a blocked air vent inside the fridge, a faulty door seal, or a failing evaporator fan. Check the condenser coils and door seal first these two account for the majority of “fridge not cooling” service calls we get across Barrie.
A refrigerator that’s running but not actually cooling is one of the most common calls our technicians get in the Barrie area. Here’s the order we check things in. You can run through the same list before booking fridge repair in Barrie.
1. Dirty or Blocked Condenser Coils
The condenser coils (usually at the back or underneath the fridge) release heat as part of the cooling cycle. When they’re coated in dust and pet hair, the fridge has to work harder and eventually can’t keep up.
Check it yourself: Unplug the fridge, pull it out, and vacuum the coils. If your fridge is more than 2 years old and this has never been done, this is very likely your issue.
2. Blocked Air Vents Inside the Fridge
Fridges circulate cold air from the freezer section through internal vents. If those vents get blocked usually by food containers pushed too close to the back wall the fridge section stops receiving cold air even though the freezer stays cold.
Check it yourself: Look for a vent (usually a small grille) on the back interior wall. Make sure nothing is touching or blocking it.
3. Faulty Door Seal (Gasket)
A worn or torn door gasket lets cold air escape continuously, forcing the compressor to run constantly without ever reaching the set temperature.
Check it yourself: Close the door on a piece of paper. If you can pull the paper out easily, the seal isn’t gripping properly.
4. Failing Evaporator Fan
This fan circulates cold air from the evaporator coils throughout the fridge. If it’s failing, you’ll often hear a faint buzzing or clicking sound, and the freezer may still be cold while the fridge section is not.
This is not a DIY repair accessing the evaporator fan means removing the back panel of the freezer compartment.
5. Refrigerant Issues
Less common, but possible in older units. If coils are clean, vents are clear, and the seal is intact, but the fridge still isn’t cooling, a refrigerant leak may be the cause. This requires a certified technician refrigerant handling is regulated in Ontario.
6. Thermostat / Control Board Failure
On newer fridges with digital controls, a failing control board can cause inconsistent or absent cooling even when every mechanical part is working fine.
Quick Self-Check Table
What to Check | Time It Takes | Fix the Issue? |
Condenser coils (vacuum clean) | 15 minutes | Often, if dusty |
Interior air vents | 2 minutes | Sometimes |
Door seal (paper test) | 2 minutes | If seal is worn |
Evaporator fan | N/A — call technician | Requires diagnosis |
Refrigerant / control board | N/A — call technician | Requires diagnosis |
Frequently Asked Questions (FAQs)
This is a classic sign of either a blocked internal air vent or a failing evaporator fan. Check the vent first; it’s the simpler fix.
Every 6–12 months, or more often if you have pets. It’s one of the easiest ways to prevent a “not cooling” service call.
It’s time-sensitive for food safety; refrigerator temperature should stay below 4°C. If it’s been warm for more than a couple of hours, move perishables to a cooler and book same-day service.
Simple fixes (coil cleaning, seal replacement) typically run $100–$200. Fan or control board repairs range $200–$450 depending on the part. Book fridge repair in Barrie with Master Appliance →
