Errors of air conditioners General Climate: decoding of codes and ways to deal with malfunctions

Brand air conditioners General Climate, or GC, do not cause problems for their owners for a sufficiently long period after purchase. But still, like any equipment, they are subject to wear and tear and malfunction. Depending on the model, air conditioning errors General Climate are displayed on the remote control screen or displayed through various combinations of light indicators on the built-in display of the indoor unit.

After reading our article, the owners of the climate technology of this brand will know what the appearance of various symbols on the display means, and will also learn to understand the numerous combinations of indicator signals on the indoor unit of the product.

The information collected and presented by us will help the owners of the equipment to understand the methods of eliminating errors and teach them to do the right thing in case of a violation in the work.

Self-diagnosis system of modern air conditioners

A new generation of household appliances is usually equipped with a self-diagnosis system designed to detect malfunctions and errors in operation when they first appear. Self-diagnosis system - a single network of sensors that monitor the status of a particular working unit of the unit.

When the air conditioner is turned on, the sensors automatically start working and continue to perform their functions in continuous mode until the device is disconnected from the power supply. Sometimes, to eliminate failures and errors, it is enough for the owner of the air conditioner to carry out simple actions with his own hand, sometimes you have to invite masters from an authorized service General Climate.

Consider possible errors and their codes in various models of air conditioners and splitGC systems, causes of their occurrence and methods of elimination. We will try to figure out in which cases handwritten actions are appropriate, and in which an experienced master should be invited.

GC air conditioners are equipped with a modern self-diagnosis system that sends signals in case of failures and errors in operation to the control module

When changing the operating parameters of the node on which the sensor is installed, an error signal is immediately sent to the control module, which is displayed on the display of the device. If necessary, the control module also locks the equipment to avoid incorrect operation of the air conditioner and its final breakdown.

Fault codes for various models air conditioners General Climate may differ from each other. We will try to consider in detail the codes of each model.

STANDART Series Error Codes

In different models of STANDART split systems, the error symbols may differ, therefore, before fixing the problem, it is necessary to clarify in the instructions the exact name of the model of the split system and its internal and external units. Only then can you start decrypting the error code.

The exact name of the model of the air conditioner or GC split system can be found in the instruction manual attached to the equipment when purchasing

We also define the notation:

• start indicator - Operation;
• timer - Timer;
• defrost indicator - Defrost;
• automatic mode - Auto.

When decrypting the error code, it is very important not to confuse the flashing, blinking and extinct indicators, the accuracy of determining the problem depends on this.

Bug Fixes

Despite the different error codes in different models of General Climate air conditioners, in fact all the failures and breakdowns in them are the same.

Consider what to do to the owner of the equipment in the event of a particular error:

1. Fan stop. If the fan fails to start for more than 1 minute, check the connection of the fan motor, as well as its serviceability. In the event of a component breakdown, it must be replaced. The air conditioning fan may also malfunction if there are problems with other components. For such diagnostics, it is recommended to invite an experienced wizard from a specialized service.
2. Problems with temperature sensors. If the self-diagnosis system gives an error of a sensor, it is necessary to check the condition of the part, its integrity and the correct connection. For such a check, the owner of the air conditioner will need a multimeter. If the sensor fails, replace it.
3. EEPROM crash. Sometimes you can get rid of the EEPROM error by simply restarting the air conditioner. To do this, turn off the power for a few minutes, then turn it on again. If the reboot did not help, the cause is problems with the electronic board. For such repairs, it is also recommended to invite a certified repairman.
4. The compressor does not start. Compressor malfunctions usually begin after the filter is clogged with dust and dirt. The cause of the part failure can be overheating, damage to the winding or cable. The owner of the equipment can independently clean the filter of the device, but for more complex manipulations you will need an experienced locksmith.
5. Repeated high voltage supply. With such an error, you should first disconnect the air conditioner from the power supply. The error will be automatically removed after regulating the power supply to the device.
6. Communication failure between system units. Lack of communication leads to blocking the operation of the split system. The owner of the air conditioner can independently check the connection of the inter-unit cable and its integrity. If everything is in order with the cable, it means that the matter is in the electronic circuit boards of the blocks, and you need to contact the master.

It should be noted that malfunctions and malfunctions in the operation of air conditioners will occur much less frequently with regular routine inspection of household appliances.

Regular and timely cleaning of equipment and replacement of worn parts will ensure uninterrupted operation of air conditioners and split systems for a sufficiently long period.

Experienced masters of authorized service centers will qualitatively and in a short time tidy up a failed air conditioner or split system

To repair HVAC equipment, it’s advisable to contact a service center accredited by the manufacturer in order to restore the functionality of the GC air conditioners and carry out preventive maintenance, in which craftsmen with the appropriate approval work.

Conclusions and useful video on the topic

Timely disassembly and cleaning of the air conditioner will help to avoid errors in operation:

An example of a signal light indicator of the air conditioner when an error occurs:

This video demonstrates how to disassemble the General Climate air conditioning fan motor with your own hands:

If error messages appear, the owner of the General Climate air conditioner should not delay their removal. Self-repair of household appliances requires certain skills and the availability of specific tools. If the owner of the unit has both of them, he may well try to fix the breakdown on his own.

Otherwise, interference with the complex mechanism of an air conditioner or split system is fraught with more serious problems. An inexperienced owner of the equipment is recommended to invite an air conditioning repairman from an authorized service without trying to fix the device with your own hands.
