How to repair LG Air Conditioners?

Introduction

Air conditioning is an absolute necessity in some parts of the world. In these parts of the world, excessive heat makes a living hell without the use of air conditioners. In other parts of the world where the weather isn’t so extreme, Air Conditioners are still needed, whether in summer or in some factories where machines constantly produce heat and need cooling. Air conditioning is a system that controls the air in an enclosed space by removing the heat in it and replacing it with some humidity, to provide some coolness. In a nutshell, air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). 

 

Air condition repairs can be quite expensive, depending on the fault being fixed. Hence, it is advisable that regular troubleshooting and maintenance is carried out as a preventive measure to both common and even uncommon faults. The premise of an air conditioner is basic: air needs to flow through it for it to work its magic and this is the reason why most central air conditioning problems occur when rooms are closed off and airflow through the home is disrupted. However, the case is quite the opposite when you are dealing with a room air conditioner- room air conditioners are restricted to smaller spaces like air-tight rooms rather than an entire home or a large business space. In the same vein, other air conditioner problems result from, poor service procedures, faulty installation, and inadequate maintenance.

About LG

 

In 1958, LG Electronics was founded as GoldStar, after the merger of two prominent Korean Companies-Lak-Hui which means ”Lucky” and Goldstar were merged together to form the company now commonly known as LG. It was only fair that the merged company bore the identity of both companies after the merger was concluded, hence the Acronym stood for Lucky and GoldStar. Shortly after this merger, Household Appliances were sold under Lucky while other Electronics were marketed using the GoldStar brand name but even at the time, LG had not risen to the prominence it has so far acquired. Product Quality was not as great as it is today, hence they were also inexpensive, yielding very little profit every quarter. However, 1995, marked the start of other events that exposed the company to the Limelight. In that year, LG was now known as ‘Life’s Good Electronics’ simply termed LG Electronics, in the same year, the company acquired a US Electronics Company named Zenith at the time. Subsequently, LG Electronics made the world’s first CDMA digital mobile handsets and supplied them to Ameritech and GTE in the U.S. Achieves UL certification in the U.S. In 1998, LG developed the world’s first 60-inch plasma TV. In 1999, LG established LG Philips LCD with Philips

 

By 2005, LG Electronics had risen above all forms of obscurity to sit among the top 100 global brands. A year later, LG had recorded a brand growth of 14% and now in present times, LG Display, its Display Manufacturing affiliate is now the world’s largest plasma panel manufacturer. LG’s transition from a low-level company, delivering relatively sub-standard products to a World-class Company, now delivering state-of-the-art products was not just an overnight leap. Not only did LG have to re-establish itself as a higher quality manufacturer, it also has to create a balance between products’ aesthetic beauty and standard quality. When LG erased the Lucky Goldstar brand and re-launched it as LG. This was not just a marketing activity. It was not merely about a new advertising campaign. The product had to be improved. This was a design and manufacturing challenge. LG did this over time, not instantly. The transformation spanned decades of brand development. Now, LG operates through the following business areas: Home Entertainment, Mobile Communications, Home appliances, Air-Conditioning, Energy solutions,s and Independent business




The move towards the luxury end of the spectrum did not take place overnight. First, LG had to establish itself as higher quality, more reliable, more desirable brand than its Lucky Goldstar heritage. When LG erased the Lucky Goldstar brand and re-launched it as LG. This was not just a marketing activity. It was not merely about a new advertising campaign. The product had to be improved. This was a design and manufacturing challenge. LG did this over time, not instantly. The transformation spanned decades of brand development.

Common Problems with LG Air Conditioners

You are certain to feel some frustration or disappointment when you push your LG Air Conditioner power button, expecting it to work as always but you shockingly discover that it is in one way or another faulty. It is rare to find faults in your LG Air Conditioners because they’ve been built to be strong and durable, withstanding some level of pressure but some common mistakes like improper installation and inadequate maintenance may affect the longevity of this product and cause it to short live its years. It is necessary to have some knowledge of the problems that your Air Conditioner can possibly encounter in order to tackle some problems using the right approach. The common faults encountered in LG Air Conditioners will be studied below.

LG Air Conditioner Not Cooling 

 

The sole function of an Air Conditioner is to humidify the air it passes into the room, thereby causing some coolness. When this isn’t happening it is clearly because some things aren’t in place, hence they need fixing. An LG Air Conditioner’s not cooling could be a result of a number of factors, one of which could be insufficient power supply into the Air Conditioner. There is a specified amount of current that should pass into your LG Air Conditioner for it functions as it should. in the same vein, the Air Conditioner may have been connected to the wrong power outlet, hence that needs checking. For some precision in your troubleshooting, you may consult the model’s manual for specific power requirements.

 

High outdoor temperatures can also be the reason your Air Conditioner is not cooling as well as it should. An extremely hot temperature could make it difficult for the air conditioner to keep up. Drafts, open windows, or an open fresh air vent on the air conditioner can let hot outside air into the room. This also makes it more difficult for the AC to cool properly. If the unit is too small for the room, it might run nonstop without getting cool enough.

 

In the process of troubleshooting your Air Conditioner, it is important also to check the compressor. You can do this by leaving the AC disconnected for at least 30 seconds. Make sure the AC stays disconnected for as long as 30 seconds or even longer because, If you turn it back on sooner, the safety switch might kick into effect and stop the unit from running for three minutes. After 30 seconds, reconnect the AC to power and choose the cool setting on the lowest temperature and you should be able to hear the startup and the little hum of the compressor when it starts running. If not, seek professional expertise.

LG Air Conditioner Won’t Turn On

 

Do not be presumptuous here, check the power source to ensure that there has not been any disconnection. An unplugged unit may just be the cause of your AC problems. You can even troubleshoot by testing a lamp or another small appliance in the electrical outlet to see if it is an issue with the electrical outlet or the air conditioner itself. However, for some newer models with a ground-fault circuit interrupter on their electrical cord, all you may need to do is hit the reset button to solve the power issue. 

 

If you eventually discover that it doesn’t work, check the circuit breaker for the air conditioner to verify that it’s turned on. Flip the breaker back to the “on” position if it was tripped. LG air conditioners need a dedicated circuit to handle the power draw safely. If you use the circuit for other items, it’s more likely to become overloaded.

LG Air Conditioner Doesn’t Run

 

It is best practice to isolate the circuit of your Air Conditioner Circuit because when its circuit is shared with other Appliances it stands the risk of insufficiency in power supply. When this is the case, the AC will not run. There may even be enough power running through it to turn on the indicators but it will not run or cool if there is not enough power to serve it.

 

If the room temperature is the same as the temperature that you have set your AC to work on, there is a possibility that the AC does not run or cool. Once the room reaches the desired temperature, your LG air conditioner stops running. If the temperature rises, it starts running again. Lower the temperature setting to see if the LG AC starts running. If not, call a professional to diagnose and repair the problem.

How to troubleshoot an LG Air Conditioner problem

 

Although it is handy to fix a faulty Air Conditioner by yourself when the fault is minimal, however, for some faults, you may just have to consult professionals because doing it yourself may attract even graver damage that will require you to take a trip to the store. After adding up the labor and parts costs, repairing a window unit may not be as economical as replacing it, especially if your unit is out of warranty or past its life expectancy, which is an average of 10 years. 

 

Some of the problems you may encounter with an LG Air Conditioners include the following

 

  • Air Conditioner not cooling
  • Improper Installation
  • Air vents blocked or dirty 
  • Water leaking from Air Conditioner
  • The Air Conditioner unit does not power on 
  • Air Conditioner remote not working.
  • Air Conditioner not cooling 

 

All this Air Conditioner needs may just be a simple adjustment to its setting. It is important to first check if the AC is set to cool.  Verify the unit is set to cool and then set the temperature to its lowest setting which is 60 degrees Fahrenheit on most LG models equipped with a digital display. After setting the AC to cool, the fan speed needs some adjustment to its maximum setting. That being done, check the unit for cold air; however, if it is not blowing cold air, it may require a refrigerant recharge by a certified professional.

Improper Installation

 

When your unit is not properly installed, the AC may not work as great as it should. Hence, you should verify that the AC has been properly installed and that the unit is not obstructed in any way. To do that, Check to ensure the airflow to the unit is not restricted. The unit must be installed with proper clearances on both sides and at the rear with no obstructions to impede airflow. The second thing to do is ensure that there is no obstruction to the AC’s intake of air from within. When this is done, confirm that the unit has at least a minimum of 20 inches between its exhaust and any obstructions.

Air vents blocked or dirty

 

When air vents are blocked by dirt, it could also obstruct the free flow of air in and out of the AC units. Thus, frequent checks and cleaning are necessary to remove any dirt lurking in the AC vents.

AC Unit Leaking Water

 

For wall and window air conditioners, check the angle at which the unit is installed. The unit must tilt toward the outside from at least 1/4 to 1/2 inch in order to properly drain condensation from the base pan to the outside. If this option does not rectify the issues, the LG LW6019ER Window Air Conditioner is a good option for replacement.

AC Error Codes

Some LG models give you a clue about the issue with error codes. Specific codes can vary by model, so check the manual for guidance. Some examples of codes include:

  • P2 or FL:​ Full drain pan.

  • CH34:​ Shut down the safety relay to avoid overheating due to abnormal pressure.

  • E1 or CH02:​ Short or open circuit in the indoor pipe sensor; requires repair.

  • E3 or CH03:​ No refrigerant detected; requires professional repair.

  • E4:​ Indicates defrost mode (not an actual error) with AC turning on after it defrosts.

  • E5:​ Full water collection tank.

  • F1, F2, F3:​ Not an error code but an indicator of fan speed.

Air Conditioner Maintenance Tips 

The fact that poor and irregular maintenance causes grave damage to your Air Conditioner cannot be emphasized enough. Do It Yourself Air Conditioner maintenance can go a very long way to prevent some common Air Conditioner problems. Below are some maintenance tips for your LG Air Conditioner.

Regular Vent Cleaning

  • Check the unit for accumulated dirt or debris. The vents, air filter, evaporator coils, and condensing coils need to be kept clean through regular preventive maintenance to assure maximum cooling efficiency and longevity of the unit.
  • Check and clean the air filter at least twice a month.
  • Check the evaporator coils and condensing coils at least seasonally and, when needed, carefully clean them using the brush attachment on a vacuum cleaner.

Remote Control Maintenance

 

Inspect the batteries in your remote control to see if they are in condition or need replacement. If they need to be replaced, do so with recommended pairs and not substandard ones. Also, ensure that they are installed in the right direction. And lastly, verify the battery contacts are clean and that the batteries fit tightly enough to make a proper connection. If these options do not yield positively, you may need a LG Air Conditioner Remote Control replacement.
