LG Refrigerator Help

Step – (1.) Dirty Condenser Coils

The condenser coils are located under the refrigerator, behind the grill at the very bottom of the fridge.  If the condenser coils become clogged with dust and pet hair etcetera, there won’t be sufficient air flow being moved by the condenser fan across the coils.  If the coils can’t release the heat, the refrigerator will strain to stay cool.  You can remove the kickplate from the bottom of the refrigerator and clean it if it is needed, then inspect the condenser coils for dust buildup, if there is buildup present, it will need to be removed.  You can remove the dust using a vacuum hose and small attachment or a long narrow refrigerator coil brush, which can be purchased fairly cheap from your larger hardware stores.  You will need to be careful not to damage any of the electrical wires or components on the compressor or damage the condenser motors fan blades.  This should really be done at least once a year if you have pets that shed in the house or live in a dusty environment.

Step – (2.) Evaporator Fan Motor

The evaporator fan motor is used in side-by-side refrigerators and refrigerators with a top or bottom freezer to circulate air over the evaporator coils which converts heat from the coils into cold air that is then circulated throughout the refrigerator from the spinning fan blade.  The evaporator fan motor is located in the back of the freezer compartment on a refrigerator.  The most common symptoms of a defective evaporator fan motor are, the refrigerator is warm, the refrigerator is noisy, the freezer compartment is too warm, or both the fridge and freezer are too warm.

Step – (3.) Condenser Fan Motor

The condenser fan motor is located in the very bottom part of the refrigerator behind the access panel on the back side of the fridge.  It is used to draw cool air through the front grill and circulate the air around the compressor and through the condenser coils, then moving the hot air out into the room.  It also aids in evaporating water from the drain pan beneath the fridge.  Some typical symptoms of a faulty condenser fan motor are, the refrigerator is warm, the fan turns slower than normal, the compressor is noisy or the freezer is warm.

Step – (4.) Temperature Control or Cold Control

Check the cold control knob located in the refrigerator section, is it set at too warm of a position?  If so, this will not allow the fridge to operate often enough to stay cold, try turning the dial to a colder position.  Repair Note – The refrigerator cold control dial should only be turned about 1/8 of a turn in a 24-hour period, you will need a refrigerator thermometer to adjust and set the refrigerators temperature correctly, you can purchase a refrigerator thermometer fairly cheap from almost any hardware store.  The factory suggests the cold control knobs indicator dial be set at the mid-range, 12 o’clock position.  The optimum temperature inside of a refrigerator for safe food storage is in between 34 to 40 degrees Fahrenheit.   If the temperature is any colder than 34 degrees F food will freeze, any warmer than 40 degrees F food will start to spoil quickly.  Adjust the cold control knob 1/8 of a turn every 24 hours, and take notes of how much colder the fridge has become and repeat the process until you hit the optimum temperature range, between 34 degrees F and 40 degrees F.

Step – (5.) Overloading The Fridge

If the refrigerator shelves have been overloaded with food, sometimes this can block the normal cold air flow into the fridge’s cabinet from the air inlet damper, thus not allowing the cold air to circulate into the refrigerator section.  Overstocking the shelves can also disrupt the refrigerators air flow system, not allowing the cool air to circulate properly the way the refrigerator was designed to do.

Step – (6.) Refrigerator Door Gasket

The fridge may be warm caused by a defective door gasket.  If the refrigerator’s door gasket is not making a proper seal between the fridge’s door and the console, this will let the cold air escape and the room temperature air to enter.  Visually inspect around the door and make sure that the gasket is sealed correctly into position and does not have any folds, creases or gaps anywhere.  This usually happens around the corners of the door gasket.  If the gasket is damaged, it will need to be replaced to solve the problem.

Step – (7.) Door Light Switch

The door switches operate the lights in both the refrigerator and freezer’s food compartments, the light switch also operates the evaporator fan motor in the freezer section.  When the refrigerator door is open, this releases the switch to the off position and the evaporator fan shuts off.  If the light switch has failed, the evaporator fan won’t be able to circulate the cold air into the refrigerator cabinet.  Test the light switch for continuity using an analog multimeter or a digital meter, if the switch has continuity, it is good.  If the test shows that it does not have continuity, it is defective and the switch will need to be replaced.

Step – (8.) Light Stays On

If the refrigerators interior light stays on, this can cause the refrigerator to get warm.  You can test the light switch for continuity using a digital or analog multimeter, if the test shows the switch has continuity, it is good.  If the test shows no continuity, the switch is defective and will need to be replaced.

Step – (9.) Excessive Use

If the refrigerator is being used more often than normal, repeated door openings in a short amount of time will cause the temperature in the refrigerator to rise temporarily, then cool back down to normal operating temperature the longer the refrigerator door stays shut.

If your LG refrigerator’s not running and it will not start, follow these four troubleshooting steps to help you locate where the problem is so you can repair or replace the faulty part or parts and get your refrigerator up and running again.

WARNING – If you are attempting to repair any refrigerator yourself, be aware that you are working with potentially dangerous electrical currents that can cause serious bodily injury or death.  Always remove the electrical power source from the appliance before you ever begin working on it.  If you are attempting to repair any household gas appliances yourself, always be sure to turn off the gas that is designated to the appliance before you ever begin to repair it.  Be aware that refrigerators have extremely sharp edges and moving parts that can cause serious bodily injury or death.  Be aware that there are many other dangers and precautions involved with a refrigerator repair besides those listed above.  We strongly suggest that you please read our DISCLAIMER before any further actions are taken or proceeding any further.  Think safety first!

LG Refrigerator

Step – (1.) Incoming Electrical Power

If your LG refrigerator won’t run or the compressor is not kicking on, first you will need to begin by troubleshooting the simple repair solutions.  Step – (1) Open the refrigerator door to see if the interior light is working, if the refrigerator’s light is working, you can move on to step – (2) below, If the interior light is not coming on and the fridge is not running you will need look for a blown fuse or a tripped circuit breaker in your home’s main circuit breaker box.  If you do not have a blown fuse or a tripped circuit breaker you will need to test the electrical wall outlet with a voltmeter.  If you do not have a test meter, try plugging something else that runs on 110 volts into the outlet to see if the outlet is faulty or working properly.  If you do have a test meter, the wall receptacle test should check at 115V plus or minus 10 percent.  If the receptacle is bad you will need to replace it with a new one.

Step – (2.) Overload or Relay Start Capacitor

If you can hear a clicking sound coming from the bottom of the refrigerator and you can see the fan working but the compressor is not kicking on, it could be that either the start relay or the run capacitor have failed.  They are both mounted onto the side of the refrigerator’s compressor.  The start relay is used to help start the compressor, it is used as a jump start device.  If the overload or relay start capacitor is not working the compressor will not start running.

Step – (3.) Temperature Control Thermostat

The temperature control thermostat is located inside of the refrigerator section.  You will need to look for the control dial that has the word off printed on the face of it.  This is the control that turns the compressor on and off.  Now go ahead and turn the dial or knob to the off position, then turn it back to the on position.  Did the compressor kick back on?   If the compressor did not start you will need to test the thermostat using a test meter.  Testing the temperature control thermostat – Place the meter probes on the thermostat’s terminals, set the range scale on (R x I) and test the part for continuity.  With the control dial set in the off position, you should not read any continuity, when the control dial is set to the highest position, you should read continuity on the meter.  If the control thermostat does not have any continuity, it will need to be replaced with a new part.  If the test shows that it does have continuity, more troubleshooting will need to be performed on the refrigerator.

Step – (4.) Electronic Circuit Control Board

You will need to inspect the refrigerator’s electronic control board, only used on some modern refrigerator models.  The circuit control board can be a very difficult part to test.  The board is a very intricate electrical part, sometimes a hairline fracture in a tiny soldered spot can cause the whole board to fail.  You won’t even be able to see the fracture in the solder without using a magnifying glass.  You can visually inspect both the front and back sides of the control board.  You should be looking for a loose wire harness connection or a burnt or melted electrical component on the control board.  If any obvious damage to the board is found, the part is more than likely faulty and will need to be replaced with a new part.

If you have noticed that your LG refrigerator’s getting too cold and freezing some of the fresh food and liquids, follow these four troubleshooting steps to help you locate and repair the problem.  It might be as simple as turning two knobs that adjust the temperature setting in your fridge to get it cooling properly and at the desired temperature again.

WARNING – If you are attempting to repair any refrigerator yourself, be aware that you are working with potentially dangerous electrical currents that can cause serious bodily injury or death.  Always remove the electrical power source from the appliance before you ever begin working on it.  If you are attempting to repair any household gas appliances yourself, always be sure to turn off the gas that is designated to the appliance before you ever begin to repair it.  Be aware that refrigerators have extremely sharp edges and moving parts that can cause serious bodily injury or death.  Be aware that there are many other dangers and precautions involved in refrigerator repair besides those listed above.  We strongly suggest that you please read our DISCLAIMER before any further actions are taken or proceeding any further.  Think safety first!

LG Refrigerator

Step – (1.) Air Damper Control

If your LG refrigerator is getting too cold, you might have noticed some items in the refrigerator compartment are frozen.  The air damper control, also known as the air inlet damper, air baffle or diffuser is used to balance the cold air flow from the evaporator housing to the refrigerators fresh food holding section, on most models.  The inlet damper is made of plastic, with louvers like window blinds and is usually located on the interior wall of the fresh food compartment toward the bottom of the fridge.  The control knob for the damper is located next to the fridge’s cold control knob.  It might have freezer printed above or below it, it will be the knob (without) the off-position option.  Is the knob set on too cold of a position?  If so, move the knob a little bit to the warmer position.  You should be able to open and close the damper by adjusting the damper control knob.  If the damper diffuser is broken it will let too much cold air into the refrigerator, freezing the fresh food.  The optimum temperature inside of a refrigerator for safe food storage is between 34 to 40 degrees Fahrenheit.   If the temperature is any colder than 34 degrees F food will start to freeze, if the temperature is any warmer than 40 degrees F the food will start to spoil.  You will need a refrigerator thermometer to adjust and set the fridges temperature correctly.  You can purchase a refrigerator thermometer fairly cheap from almost any hardware store.  The factory suggests that the air inlet damper knobs indicator dial be set at the mid-range, straight up 12 o’clock position.

Step – (2.) Cold Control or Temperature Control

You will need to check the cold control knob/dial located in the refrigerator cabinet, is it set at too cold of a position?  If so, try turning the dial to a warmer position.  Note – The refrigerator cold control dial should only be turned about 1/8 of a turn in a 24-hour period.  You will need a refrigerator thermometer to adjust and set the refrigerator’s temperature correctly.  You can purchase a refrigerator thermometer reasonably cheap from almost any hardware store.  The factory suggested setting for the temperature control is mid-range, this means that the indicator on the dial/knob should point in the 12 o’clock position.  The optimum temperature inside of a refrigerator should be between 34 to 40 degrees Fahrenheit for safe food storage.   If the temperature is any colder than 34 degrees F food will freeze, any warmer than 40 degrees F food will start to spoil quickly.  Adjust the cold control knob 1/8 of a turn every 24 hours and take notes of how much colder the fridge has become and repeat the process until you hit the optimum temperature range, between 34- and 40-degrees Fahrenheit.

Step – (3.) Thermistor Or Temperature Sensor

If your refrigerator is equipped with an electronic control board the temperature is going to be controlled by a thermistor.  This part is usually located near the fridge’s air inlet, the thermistor senses the temperature and relays it back to the refrigerator electronic control board.  The control board will then monitor the temperature and will make the necessary adjustments to the cold air inlet damper as they are needed.  The temperature sensor could be faulty if it’s too cold in the fridge compartment.

Step – (4.) Refrigerator Main Control Board

A faulty main control board could be the reason why the refrigerator is too cold.  The control board is used to control a multitude of a refrigerator’s parts and functions.  The control board is a very difficult part to test.  You can visually inspect the fridges control board for burnt spots, melted relays, solder joints or any other obvious signs of electrical damage and replace the board if you see any of the mentioned damage.  Electronic control boards aren’t cheap, some control boards can be pretty pricy.  Only after troubleshooting all of the other refrigerator’s components that could be at fault for the reason your refrigerator is getting too cold, should you suspect the electronic control board to be the main culprit.
