Samsung Fridge Not Cooling But Freezer Works: Auburn Bay, Calgary [Case Study]

Case Study: A homeowner in Auburn Bay, SE Calgary, contacted Calgary Appliance Fix after noticing their Samsung fridge not cooling but the freezer working — the freezer was fine, but the fridge temperature was running too high, and food was not staying cold as it should. Our technician Alex, a licensed appliance technician with over 15 years of experience, was dispatched to diagnose the problem.

The Symptom: Samsung Fridge Not Cooling But Freezer Working Fine

A Samsung refrigerator where the freezer is cold but the fridge section is not reaching the right temperature is one of the most common refrigerator complaints we receive across Calgary and surrounding areas. It is easy to assume the worst when food starts warming up — but in most cases the cause is a specific component failure, not a sealed system issue or compressor problem.

In this Auburn Bay home, the fridge temperature consistently ran above the set point. The food was not staying as cold as it should, and the homeowner had noticed the issue was getting progressively worse over several days.

The Diagnosis: Ice Buildup on Evaporator and Defrost System Failure

When Alex opened the freezer and removed the back panel to inspect the evaporator coil, the cause was immediately clear. There was significant ice buildup on the top right of the evaporator coil and some ice on the evaporator fan. This is a classic sign of defrost system failure.

Here is what was happening inside the Samsung refrigerator:

The evaporator coil is the component that gets extremely cold to produce the cooling effect inside the fridge. The defrost system is designed to periodically melt any frost that builds up on the coil so it can keep working efficiently. When the defrost system fails, frost accumulates on the coil over time and eventually turns into a thick sheet of ice. Once the coil is blocked with ice, the evaporator fan cannot push cold air through it properly — so the freezer stays cold because it surrounds the icy coil, but the fridge compartment does not receive enough cold air.

In this case, ice had built up heavily on the top right of the evaporator and was beginning to block the fan. The defrost heater had failed and was no longer melting the frost buildup as it should. The control board, which manages the defrost cycle timing and temperature regulation, had also failed — contributing to the defrost system breakdown.

Alex diagnosed two components that needed to be replaced: the defrost heater and the main control board.

The Repair: Manual Defrost, Heater Replacement and Control Board Replacement

Before any parts could be installed, the ice buildup on the evaporator coil and fan needed to be completely cleared. Alex carefully melted down all the ice manually to restore the evaporator coil to a clean working state. This step is essential — installing a new heater without clearing the existing ice buildup first would not resolve the problem properly.

Once the evaporator was clear, Alex installed the new defrost heater. The heater sits alongside the evaporator coil and activates periodically to melt frost before it can accumulate into ice. With the old heater failed, frost had been building unchecked for an extended period.

The main control board was then replaced. The control board on a Samsung French-door refrigerator manages defrost cycle scheduling, temperature sensing, fan operation, and overall system coordination. A failed control board can prevent the defrost cycle from activating at the right intervals — which is exactly what had happened here alongside the heater failure.

After both components were replaced, the refrigerator was tested. The fridge temperature began dropping toward the correct range, the evaporator fan was running freely, and the defrost system was operating on the correct cycle. The Samsung refrigerator was fully restored to proper working order.

The homeowner was very happy — their fridge was cooling properly again, and their food was safe.

Why Samsung Refrigerators Are Known for Ice Buildup Issues

Samsung French door and bottom-freezer refrigerators are one of the most common models we repair across Calgary for exactly this type of fault. Ice buildup on the evaporator coil due to defrost system failure is a well-known issue on Samsung refrigerators, particularly on models manufactured between 2012 and 2020.

The root cause is typically a combination of a defrost heater that fails earlier than it should and a control board that does not always manage the defrost cycle correctly. When both fail around the same time — as happened in this Auburn Bay case — the ice builds up quickly and the fridge compartment loses cooling within days.

If you own a Samsung French door refrigerator and notice your fridge temperature climbing while the freezer stays cold, do not wait. The ice buildup will worsen and the evaporator fan can be damaged if it runs against a solid block of ice for an extended period.

What Happens If You Ignore Ice Buildup in a Samsung Refrigerator

Many homeowners try to manage a Samsung refrigerator ice buildup issue by manually defrosting the fridge — unplugging it for 24 to 48 hours to melt the ice. This can temporarily restore cooling, but the underlying cause remains unfixed. Without replacing the failed defrost heater and control board, the ice will build up again within days or weeks and the problem will return.

A proper repair addresses the root cause — not just the symptom. That is what Alex did in this Auburn Bay home, and the result was a refrigerator that will continue to operate correctly without the homeowner needing to manually defrost it repeatedly.

Frequently Asked Questions: Samsung Refrigerator Repair in Calgary

Why is my Samsung fridge not cooling but the freezer is fine?

The most common cause is ice buildup on the evaporator coil due to a failed defrost heater or a defrost system fault. When the coil is blocked with ice, cold air cannot circulate into the fridge compartment properly. A technician can diagnose and repair the cause in a single visit.

Why does my Samsung refrigerator keep getting ice buildup?

Samsung French door and bottom-freezer models are known for recurring ice buildup caused by defrost heater failure and control board issues. Simply defrosting the fridge manually is a temporary fix — the defrost heater and in some cases the control board need to be replaced to permanently resolve the problem.

How quickly can you come for Samsung fridge repair in SE Calgary? 

We offer same-day and next-day refrigerator repair throughout SE Calgary including Auburn Bay, Mahogany, McKenzie Towne, and surrounding neighbourhoods. Call 403-399-5949 early in the day for the fastest available slot.

Is it worth repairing a Samsung refrigerator with ice buildup? 

In most cases, yes — a defrost heater and control board replacement is significantly less expensive than a new Samsung French door refrigerator and fully resolves the issue when done correctly.

Do you repair Samsung refrigerators across Calgary?

Yes. Samsung is one of the most common refrigerator brands we service across Calgary and surrounding areas. We have extensive experience with Samsung defrost system failures, ice buildup repairs, and control board replacements.

Do you offer a warranty on refrigerator repairs?

Yes. Every repair completed by Calgary Appliance Fix comes with a 90-day warranty. If the same issue returns within that period, we come back at no extra charge.

Can I just unplug my Samsung fridge to fix the ice buildup?

Unplugging the fridge for 24 to 48 hours will melt the ice and temporarily restore cooling, but it will not fix the underlying defrost system failure. The ice will build up again within days or weeks. A proper repair replaces the failed components so the defrost system works automatically as it should.
