Refrigerator Repair Services in Southwestern Ontario
Professional Refrigerator Repair & Sealed-System ServiceWhen a refrigerator stops cooling properly, the problem is not always as simple as replacing a thermostat or control board. Modern refrigerators combine refrigeration systems, compressors, fans, sensors, electronic controls, defrost systems, and airflow components to maintain the correct temperatures.
IAS Repair provides professional refrigerator repair services throughout Cambridge, Kitchener, Waterloo, Brantford, Woodstock, Guelph, Stratford, London, and surrounding Southwestern Ontario communities.
We diagnose refrigerator problems ranging from not cooling and excessive frost to compressor failures, refrigerant leaks, sealed-system problems, unusual noises, water leaks, and temperature-control issues.
We also provide sealed-system refrigerator service, including eligible compressor replacement and other refrigeration-system repairs.
Call IAS Repair at 519-340-2255 to schedule refrigerator repair service.
Refrigerator Not Cooling?
A refrigerator that is warm inside does not automatically mean the compressor has failed.
Several different systems can cause a refrigerator to stop cooling correctly, including:
- Compressor
- Condenser fan
- Evaporator fan
- Evaporator system
- Condenser
- Refrigerant circuit
- Defrost system
- Temperature sensors
- Control board
- Airflow system
- Damper assembly
- Door sealing system
The first step is determining why the refrigerator is not reaching the correct temperature.
A proper diagnosis can help distinguish a refrigeration-system problem from an electrical, airflow, defrost, or control problem.

Common Refrigerator Problems
Refrigerator Not Cooling but Freezer Is Cold
This is a common refrigerator complaint.
If the freezer is maintaining a low temperature while the refrigerator compartment is warm, possible causes can include:
- Evaporator fan problem
- Restricted airflow
- Damper problem
- Frost buildup
- Defrost-system failure
- Airflow obstruction
- Temperature-sensing issue
- Control problem
The refrigerator compartment depends on proper airflow from the cooling system, so a cold freezer does not necessarily mean the entire appliance is operating correctly.
Refrigerator and Freezer Both Not Cooling
When both compartments become warm, the diagnosis can involve a different set of possibilities.
Potential causes include:
- Compressor problem
- Sealed-system failure
- Refrigerant leak
- Condenser airflow problem
- Condenser fan failure
- Electronic control issue
- Start-device problem
- Power or wiring issue
The compressor and refrigeration system may need to be evaluated before determining the appropriate repair.
Refrigerator Sealed-System Repair
The sealed system is the refrigeration circuit responsible for moving refrigerant through the appliance and transferring heat from inside the refrigerator to the surrounding environment.
Depending on the refrigerator design, the sealed system can include components such as:
- Compressor
- Condenser
- Evaporator
- Filter drier
- Refrigerant tubing
- Capillary tube or metering device
- Refrigerant charge
A sealed-system problem can produce symptoms such as:
- Refrigerator not cooling
- Freezer not reaching the correct temperature
- Excessively long compressor run times
- Partial frost pattern on the evaporator
- Compressor running without producing adequate cooling
- Gradual loss of cooling performance
- Repeated temperature alarms
Sealed-system diagnosis requires specialized refrigeration knowledge and equipment.
Refrigerator Compressor Replacement
The compressor is one of the most important components in a refrigerator's cooling system.
A failed compressor can cause the refrigerator and freezer to stop cooling, but a refrigerator that is not cooling does not automatically need a compressor.
Before recommending compressor replacement, the refrigeration system and electrical components should be evaluated to determine whether the compressor is actually the source of the problem.
Depending on the refrigerator and diagnosis, compressor replacement may involve:
- Recovering the existing refrigerant where required
- Removing the failed compressor
- Installing the correct replacement compressor
- Replacing the filter drier when required
- Connecting and brazing refrigeration tubing
- Evacuating the refrigeration system
- Performing appropriate leak and system checks
- Charging the system with the specified refrigerant
- Checking operating performance
The exact procedure depends on the refrigerator model, refrigerant, compressor, and nature of the failure.
Refrigerator Refrigerant Leak Repair
A refrigerator with a refrigerant leak may gradually lose cooling performance rather than suddenly stop cooling.
Signs that may be associated with a sealed-system leak include:
- Refrigerator gradually becoming warmer
- Freezer temperature increasing
- Compressor running for extended periods
- Incomplete or unusual evaporator frost pattern
- Poor cooling despite the compressor operating
- Previous sealed-system repair history
Simply adding refrigerant without addressing the underlying leak is not a proper long-term repair.
Where a refrigerant leak is suspected, the system should be evaluated using appropriate diagnostic methods and equipment.
Ontario regulations require certified personnel and appropriate refrigerant recovery capabilities when servicing refrigeration equipment containing regulated refrigerants.
Refrigerator Evaporator Problems
The evaporator is a critical part of the refrigeration system.
Problems involving the evaporator or its associated tubing can affect the refrigerator's ability to transfer heat and maintain proper temperature.
Depending on the appliance, symptoms may include:
- Weak cooling
- Uneven cooling
- Excessive frost
- Partial frost coverage
- Long compressor run times
- Warm refrigerator compartment
- Warm freezer compartment
An evaporator-related problem should be distinguished from a normal defrost issue or airflow restriction before determining the repair.
