LG refrigerator not cooling? Best guide to fix it.

Is your LG refrigerator not cooling? Not a problem! Home appliance repair can take much from your pocket if you seek professional help. At the same time, you can do the minor repair yourself without any cost.

We heard your LG refrigerator is not cooling, so we came to assist you in fixing your refrigerator. We have gathered some common LG refrigerator problems and solutions. Following is the list of reasons why your LG refrigerator not cooling:

Stable Power Source

The first and foremost step in diagnosis is to verify power. If the power connection is not providing enough electric voltage, it could damage the refrigerator. Even though your LG refrigerator is running fine, if you notice it’s not cooling correctly or the light is often blinking, it could be a sign to check your power source first, then your machine. Therefore, a stable power connection is essential for adequately working refrigerators.

Refregerator Location

Before installing your refrigerator, you must think of a suitable place. The ideal location for your refrigerator must fall under these conditions:

  • The temperature should not exceed or recede from 70 degrees Fahrenheit (21 degrees Celsius). This is the optimal temperature for a refrigerator.
  • If placed in the kitchen or anywhere the temperature can increase, use fans or AC to regulate the temperature.
  • Do not place it in a cool place like a garage with no heating. It will lead your refrigerator to stop as the temp will be low already. This could spoil the food inside as the fridge would have no cooling due to insulation.
  • Place your refrigerator indoors. There must be no contact of water or moisture with the machinery of the fridge.

Unbalanced or Out of Level Fridge

Reason for LG refrigerator not cooling - Installation of the fridge on uneven floor

It may not sound conceivable for users, but the fridge’s unlevel installation can cause your LG refrigerator to not cool. Make sure you install the fridge on a leveled surface. If you are certain that the surface is uneven, you should use skimps to maintain the balance of the refrigerator. Hence, when you feel like your LG refrigerator not cooling, you must check its placement first.

Overloaded Refrigerator

Reason for LG refrigerator not cooling - Overloading the fridge.

Refrigerator overloading is a common habit of many households. Which lead to the assumption that the refrigerator itself is out of order. Overloading the fridge can result in less cooling. When you fill-up the fridge with food, the cool air gets no space to fit in which causes both less cooling and ultimately spoilage of food. So, if you have an overloaded fridge you know the answer to why is your LG refrigerator not cooling.

Dirty condenser coils

LG refrigerator not cooling, dirty condenser coils may be the root cause. Do you know you’re supposed to clean your refrigerator coils every six months? Here is how you clean dirty condenser coils in five simple steps:

Step 1: Locate the condenser coils

Your refrigerator’s coils will be located around the front, near the base, covered by a panel, or around the back near the bottom. Or either exposed or covered by a panel?

Step 2: Move the Fridge

You must pull the fridge away from the wall to access them. This will be easy if your fridge has wheels, but if you still need to, lift it slightly, place furniture sliders underneath, and gently walk it out of its nook.

Step 3: Pull the plug.

It would be best if you unplug it whenever you’re doing electrical appliance maintenance. The risk may be minor; it’s just not worth getting electrocuted.

Step 4: Clean the coils

Reason for LG refrigerator not cooling - Dirty condenser coils.

Once you’ve accessed the coils in the back of or underneath your fridge, use your vacuum cleaner with a flat head attachment or a brush attachment to suck up all that dirt, dust, and debris that’s been building since the last time you did this.  

Step 5: Scrape and Spray

Negligence will have resulted in stubborn spots that won’t come off via suction. Use a stiff toothbrush or paintbrush to scrape the crud off these areas, and use a can of compressed air to spray those tight nooks and crannies you can’t quite reach.

Blocked air vents

If your refrigerator is not producing cool air, the air vents may be obstructed in some way. If the air vents are blocked, the appliance will not get any cool air outside. Check the vents within your refrigerator and freezer and remove anything that might obstruct them if they are blocked. Blocked air vents are the most common reason that your LG refrigerator not cooling properly.

Thermostat settings

For optimum functioning, you should maintain the temperature at 32°–40°F. If the temperature settings are set incorrectly, your fridge may not be cooling. Occasionally, if anything or your hand touches the controls, the temperature settings will reset.

Change the thermostat to the desired temperature setting if this is the source of your refrigerator’s issue. Check both the freezer and the fridge since they have separate settings. The shift might not occur immediately and could take up to 24 hours to fully cool.

Weary door seals

Reason for LG refrigerator not cooling - Weary door seals

it is as simple as it sounds. Depleted door seals can contribute to less or no cooling. Door seals play an important role in the insulation of the refrigerator. If the refrigerator is not sealed shut due to the weary seals, your refrigerator can not work properly.

Therefore, if your refrigerator door seals are weary, you must get them replaced by a professional. you can get a warranty if it’s still viable.

Failed Condenser or Evaporator Fan Motor

The condenser motor is another crucial element. If the motor isn’t operating correctly, you could notice your refrigerator overheating, producing unusual noises, or using more energy than usual.
First, inspect your condenser coils for any accumulation or debris obstructing the fan blades.
Your refrigerator and freezer may shut off if there is noticeably reduced airflow. You may require a new compressor motor if the problem persists after you’ve cleaned the coils and made sure the fan blades can move freely.

Refrigerator Leakage

Reason for LG refrigerator not cooling - Leakage.

Never trust an item that is dripping water, especially if it is your refrigerator. It is regrettably one of the most frequent problems with any fridge. Fortunately, the following are a few reasons you have a leaky refrigerator.

Frozen/clogged drain line:

A leaky refrigerator is dangerous for several reasons, including the potential for spoilage and damage to the cabinetry beneath the fridge if water overflows. It may even leak onto your floor.

Ensuring your refrigerator drain is not blocked or frozen is one surefire technique to avoid this. If so, you must melt the ice or use hot water to remove the debris.

Faulty tank assembly:

Poor tank assembly is another factor contributing to interior leakage. If you discover leaks, you should visually check them to see if there is any damage. If there is, make sure to replace or repair it properly. Your water input valve requires a similar inspection. Check it for damage or cracks; if you discover either, replace it immediately.

Start Relay Failure

A refrigerator start relay jump-starts the compressor within the refrigerator. The compressor might not function properly and the inside might not freeze if the refrigerator’s start relay burns out. if you find your LG refrigerator not cooling this might be the cause, lets learn how to fix it.

Types of start relays:

The two primary types of start relays are combinations and independent components. The distinct components will each have their overload in addition to the start relay. The bottom side of the relay in the combo units has an integrated overload.

How to test compressor start relays?

There are mainly two ways you can check compressor start relays:

Rattle Test:

First off, you cannot do a rattle test with an overload. The overload will always have a slight rattle to it. Since the combination units have an overload built into them, they will always have a little rattle. This style of relay will always rattle. In comparison, an individual-style relay should never have a rattle to it. If it does, then it isn’t good.

Start relay testing with a multimeter.

To test the start relay, first, make sure that this end is pointed up. 

Insert your two probes into the side, if it beeps, it’s good, if it doesn’t beep, it’s bad. If you tip it upside down it will no longer have continuity.

This is the ohm reading with it pointing up. Moreover, you can test the overload, do a visual check, and test the power going to the compressor.

Faulty Compressor

The defective compressor is consumers’ most common problem when the LG refrigerator not cooling. The compressor is the most important part of refrigerator machinery. If the compressor has a fault, you will have to replace it.

There are three different refrigerator compressors the most famous old-school split-phase compressor, BLDC inverter compressor, and LG linear compressor. They’ll look the same and can be tested the same way.

How to test compressor when LG refrigerator not cooling?

Here s a guide to testing the LG refrigerator compressor:

  • Unplug the fridge for your safety
  • Remove the back panel on the bottom of the refrigerator.
  • On the side of the compressor, you’ll see a plastic box cover that a single screw or a metal wire clamp can hold.
  • You can release those clips from the top with the screwdriver and wiggle out the rest of the cover.
  • Release the PTC start relay, which sits on two pins sticking out of the compressor.
  • Carefully move the start relay away from the compressor until you can remove it.
  • Loosen up and remove the overload protector, the overload switch, or the overload relay. It is on a single pin sticking out from the compressor, and it’s a safety device that prevents your compressor from overheating and causing a fire.
  • Switch your multimeter to ohms of resistance, and if you have different ranges, choose the smallest one. 
  • Place one of the leads on the copper pipe, and with the second lead, touch each of those three pins sticking out from the compressor individually. 
  • You should not see any changes on the screen while testing all those pins, but if you see some numbers on the screen while touching one of those three pins, your compressor is shorted to the ground and must be replaced.

How to reset an LG refrigerator

Do you still find your LG refrigerator not cooling? If all of the above information does not resolve your problem. Restarting your refrigerator can help fix minor setting issues. Knowing how to reset your LG fridge can come in handy if you have any of these typical problems or any other problems.

The refrigerator and ice plus buttons must be pressed and held simultaneously for 5 seconds after the appliance’s doors have been opened. Your panel ought to start blinking after five seconds, signifying that your refrigerator has been reset.

Resrat your fridge if LG refrigerator not cooling.

In addition, to reset the refregerator, you can also try disconnecting the appliance or trip the circuit breaker for 30 seconds. Within 24 hours, the device should settle and begin to cool, and you should hear the compressor start back up.
