TCL air conditioner errors: the specifics of decoding the problem code and repair paths

Household split systems TCL

On the market you can find an abundant number of household split systems from TCL. Such an air conditioner consists of two separate blocks, external and internal, where each performs its function. Now on the market you can find inverter and non-inverter split systems from TSL.

The popularity of inverter air conditioners is gaining momentum. Thanks to the inverted compressor, the air conditioner is able to “intelligently” regulate its speed, reducing energy consumption, noise level, increasing the service life, as well as cooling the premises faster. The communication between the blocks takes place via a digital channel.

Non-inverter systems are still popular because their price is much lower, and the main function of heating or cooling a room is performed at the proper level.

Installation of split systems should not be done alone, but it is better to entrust specialists from service centers.Otherwise, there is a high chance of losing the warranty with a completely unsuccessful installation of the air conditioner, even with a simple damage to the plastic case.

The outdoor unit is installed outside the building, it houses the compressor and fan. The indoor unit provides air conditioning. It contains all the important electronics, filters, and through it the entire device is controlled.

Almost all models of split systems are capable of producing heat, which will create a comfortable microclimate in the cool seasons. Each model is equipped with a remote control for the air conditioner.

The main characteristics that you should pay attention to when purchasing climate systems: power, area of ​​​​application, the presence of an inverter, type of refrigerant, noise level and a variety of operating modes

It is also important to pay attention to the presence of a dehumidification mode, with which the device is able to "extract" excess moisture from the room.

What you need to know about the repair and replacement of air conditioning systems?

Replacing any unit of an air conditioning system can be one of the biggest costs a homeowner will need. It's worth making sure it's the right time to upgrade.

Factors to consider when deciding whether to repair or replace

• The period of operation of the system or air conditioner - if the device is purchased for more than ten years, it is time to replace it.
• Frequency of necessary repairs - second or third repair this year? Is the repair price tag approaching half the cost of a new system? Agreeing on issues like this is a reason to stop wasting money on inefficient maintenance and save money for a more modern system.

An example of a modern air conditioner

• Electricity bill - an increase in the numbers on the payment receipt from the electric company may be one of the reasons for the increase in the bill for comfort during the cold period. Without an increase in the tariff, there were more numbers than a few years ago, which means that due to the longer service life, the system began to work less efficiently. Constantly increasing energy bills are a sign that the air conditioner has crossed the line of its heyday.
• Decrease in comfort level - It is not difficult to correlate energy costs and comfort level in the room. Uneven temperature fluctuations, cold air lowers the limits set by the user, failure to receive acceptable heat - all these are signs that air conditioning systems need to be replaced.

Instructions for the remote control and TCL air conditioners

There is a manual for the air conditioner for each type, model and product line. As a rule, one instruction is identical for the entire line and series, and therefore often in the manual you can find “excluding deviations” regarding the differences in the model range.

Classification of Kentatsu air conditioners

The Japanese manufacturer produces equipment of various capacities for equipping both private houses and small offices, as well as for large industrial enterprises, shopping, sports and entertainment centers.

In the clip of the brand - all sorts of modifications. There are several series of split systems, channel, cassette and floor units designed for small areas. Also, fan coil units, universal installations, multi-systems are produced under this brand.

Enterprises usually design combined type air conditioning systems, consisting of many elements: indoor and outdoor modules, pipelines for various purposes and lengths, additional devices to increase efficiency and comfortable control

For private use, conventional split systems are more often purchased, less often - channel, cassette and floor units. All of them consist of 2 blocks, internal and external, and serve to ensure a healthy and comfortable indoor microclimate. Let's see how they differ:

External blocks of split systems are identical in design and principle of operation, may differ in size and additional elements to increase power, protection or ease of control.

Among the split systems of the traditional type, there are inverter equipment and "on / off" models. Actual series:

• Bravo
• Quantum
• Turin
• Titan Genesis
• Mark II
• Rio
• team

Some series are no longer produced, but are still on sale. Different models differ in technical characteristics, but they are very similar in design and principle of operation, therefore the instructions for them are the same.

It is important to know that there is no error code system for split systems. Air conditioner malfunctions are determined not by the symbols on the digital display, but by objective factors - for example, the unit did not turn on or began to make uncharacteristic sounds. But channel, cassette and floor (column) models have error codes that help determine the cause of the breakdown

But channel, cassette and floor (column) models have error codes that help determine the cause of the breakdown.

Cassette: KSVQ, KSVR, KSZT

Channel: KSKT, KSTU, KSTV

Universal: KSHE, KSHF

Floor standing: KSFV, KSFW

Any of the air conditioners listed series can be installed in the cottage, if it corresponds to the area. But, according to statistics, they still use low-power split systems of the usual type with a wall module.

aux

When the equipment of the air conditioner is unstable, Aux helps users restore the equipment to work. Seeing an alphanumeric designation, it becomes clear to the user where to look for a malfunction.

Aux air conditioner error codes are presented in the form of letters and numbers. Their content is different from the equipment series. For most devices, E1 indicates problems with the indoor unit thermistor. E5 says block error outside. Seeing the encoded value, it is worth studying the instructions. This will allow you to assess the possibility of performing repairs on your own.

When Repair Is Not Necessary

Sometimes it may seem to you that the unit does not work or does not work correctly, although it is simply following the program set by the manufacturer. This applies, for example, to the delay in the execution of various commands, which can last from 3 to 10 minutes.

Delays occur due to temporary blocking. Modern technology is equipped with a 3-stage protection system:

• from frequent switching on of the compressor;
• from freezing of the heat exchanger of the external module;
• from cold air supply.

To prevent the compressor from failing quickly, there is a 3-minute turn-on delay after each shutdown.

At low outdoor temperatures, the heat exchanger is covered with a layer of frost. It takes 4 to 10 minutes to thaw. During this time, the fans are idle and the frost turns into condensation

If the outside temperature is too low, the heating of the room will be delayed. It takes at least 5 minutes to preheat or defrost the heat exchanger.

Sometimes a light "fog" begins to come out from under the blinds of the indoor unit. Its appearance is associated either with increased air humidity and temperature difference between the incoming and outgoing air, or with the period after the defrost of the external heat exchanger.

The indoor unit may make strange noises. "Gurgling" produces refrigerant moving through the pipes, creaking - expansion from heating plastic elements, slight noise - adjusting dampers.

If water starts to drip from the housing, reduce the humidity in the room: open the shutters as much as possible and increase the fan speed.

A sudden restart may occur due to power outages. Modern models turn on after turning off in automatic mode with the settings set. Some split systems need to be started manually

Work disruptions during thunderstorms are also considered normal. They occur due to electromagnetic interference. To get it working, you just need to turn the air conditioner off and on again.

New Kentatsu models come with detailed and understandable instructions, thanks to which most of the faults can be fixed on your own. In case of serious damage, contact the service center. It should be remembered that for normal operation, climate equipment requires regular maintenance, which the owner can partially perform himself.

If you are well versed in technology, you can disassemble and repair yourself, but after the warranty period has expired. Especially for home masters - a couple of interesting videos.
