How To Fix Samsung Refrigerator Not Cooling

Posted on

Welcome, MonsterWoodshop readers! Refrigerators are one of the essential appliances in our households, and a malfunction can create a big inconvenience. Samsung refrigerators are known for their quality, but sometimes they too can encounter problems. Because refrigerators are so vital, knowing how to fix them in a time of need is crucial. In this article, we will guide you on how to fix your Samsung refrigerator when it’s not cooling.

Common Reasons For A Samsung Refrigerator Not Cooling

🔧 Dirty condenser coils: Dust, dirt, and debris can accumulate on the condenser coils at the back of the refrigerator, leading to reduced airflow and inefficient cooling.

🔧 Faulty evaporator fan: The evaporator fan circulates the cold air from the freezer to the fridge, and a faulty fan can lead to a lack of cooling.

🔧 Malfunctioning fridge thermistor: The fridge thermistor senses the temperature and sends signals to the control board to control the cooling. A faulty thermistor may cause erratic temperature control or no cooling at all.

🔧 Clogged freezer drain: A clogged freezer drain can cause ice accumulation on the coils leading to ineffective cooling.

🔧 Faulty start relay: The start relay is responsible for powering the compressor, and a faulty relay can lead to a non-functioning compressor, causing a lack of cooling.

🔧 Broken compressor: A broken compressor is a severe issue that requires professional intervention, and it can cause the fridge to stop cooling altogether.

Steps To Fix A Samsung Refrigerator Not Cooling

Clean The Condenser Coils

One of the simplest reasons why your Samsung refrigerator is not cooling could be because of dirty condenser coils. Here’s how to clean them:

Steps Instructions
Step 1️⃣ Unplug the refrigerator and locate the condenser coils either at the back or bottom of the fridge.
Step 2️⃣ Use a vacuum cleaner or a brush to remove all the dust, dirt, and debris from the coils.
Step 3️⃣ Plug the refrigerator back in and turn it on to see if the cleaning has improved cooling efficiency.

Check The Evaporator Fan

If the condenser coils are not the issue, the next step is to check the evaporator fan. Here’s how:

Steps Instructions
Step 1️⃣ Locate the evaporator fan at the back of the freezer section.
Step 2️⃣ Check if the fan is turning. If it’s not, it means it’s faulty and needs to be replaced.
Step 3️⃣ If the fan is turning, but there’s still no cooling, there could be other issues like a damaged fan blade or inadequate airflow due to ice accumulation. Call a professional for assistance.

Inspect The Fridge Thermistor

If the evaporator fan is not the issue, the fridge thermistor could be the problem. Here’s what to do:

Steps Instructions
Step 1️⃣ Locate the thermistor, which is usually near the evaporator coils at the back of the freezer.
Step 2️⃣ Use a multimeter to check the resistance. The thermistor should show resistance based on the temperature sensed.
Step 3️⃣ If the resistance readings are incorrect, replace the thermistor with a new one.

Unclog The Freezer Drain

If the above steps did not fix the problem, a clogged freezer drain could be the issue. Here’s what to do:

Steps Instructions
Step 1️⃣ Locate the back panel of the freezer and remove it.
Step 2️⃣ Use hot water or a hairdryer to melt the ice inside the freezer drain.
Step 3️⃣ Clean the drainpipe and put everything back in place.

Replace The Start Relay

If none of the above steps helped, try replacing the start relay. It’s not difficult, but if you’re not confident, call a professional for assistance.

Call A Professional For Compressor Replacement

Replacing the compressor is a complex task that requires specialized equipment and skills. We suggest calling a professional to undertake this task.
