Error codes of General Climate air conditioners: decoding, troubleshooting

Our dependable air conditioners come to our rescue during the sweltering summer heat or the bitter winter cold, guaranteeing that our homes are comfortable all year round. However, air conditioners can experience malfunctions from time to time, much like any other appliance. It’s possible that if you own a General Climate air conditioner, error codes have occasionally appeared on the display, leaving you perplexed. Do not be alarmed! This post will explore the world of General Climate air conditioner error codes, explaining what they mean and offering solutions to help you get your heating or cooling system back up and operating efficiently.

The first step towards resolving any potential problems with your General Climate air conditioner is to comprehend the error codes it displays. By acting as a conduit for information, these codes let you and your appliance know when there are any issues or irregularities in the system. Even though they could initially appear mysterious, deciphering them can provide important information about the root of the issue and potential solutions.

Every error code denotes a distinct problem or malfunction in the air conditioning system. These codes offer crucial hints for accurately diagnosing a variety of problems, from straightforward ones like a dirty filter or clogged air duct to more complicated ones like a malfunctioning sensor or compressor failure. Accurately interpreting the error codes will help you expedite troubleshooting and save unnecessary frustration.

But understanding error codes is just half the fight. Effectively addressing the problem comes next after you’ve identified it. A methodical approach is needed to troubleshoot General Climate air conditioner error codes. Basic troubleshooting steps include checking for obstructions, confirming the power supply, and making sure proper airflow is in place. Depending on the nature of the issue, you might have to take certain actions or consult a professional to handle more complicated problems.

Digital codes on the control panel

Like any other contemporary split-system air conditioner, General Climate air conditioners have an integrated system made up of:

1. A huge number of sensors embedded in the most important units.
2. Microprocessor with the program of sensors interrogation, which allows to compare the received information with the one stored in the EEPROM memory.
3. Information circuitry. A message with the error code is sent to the control panel.

One can also perform the self-diagnosis manually. It is advised to run General Climate on split systems after troubleshooting or setting changes each time. The information appears on the remote control’s screen as a code, but certain models employ a flashing indicator (LED) scheme instead.

Direct communication, which appears as a message on the remote control’s screen, is only utilized in the event that there are serious malfunctions with the air conditioner that require quick attention:

1. E1 – protection tripped.
2. Error E2. Problems with thermistor controlling temperature inside the room. The device may be completely damaged (broken) or the circuit may be broken. Presumably at the pin connector.
3. Message E3 – sensor in evaporator short-circuited. In General Climate air conditioners older than 7 years, the most common cause of breakage is due to constant vibrations from the compressor operation.
4. Error code E4 – the temperature sensor of the refrigerant vapor condensation chamber does not work.
5. Error code E5 means that the drainage electric pump works with overheating. If the problem is not eliminated, the pump will jam. The General Climate outdoor unit may be damaged.
6. E6 – the error indicates the fact of triggering the general protection of the external unit. The air conditioner is stopped. The cause may be overheating, breakage of one of the phases of the power supply or any other external factors.
7. E7 – information stored in the microprocessor memory is lost. This is a critical error for all General Climate models. Only module replacement and re-flashing can be eliminated.
8. Message E8 is due to condensate overflow in the drain pan.

Regardless of the model, two of the errors in the list, E3 and E4, can have disastrous effects on the functioning of the entire General Climate split-system. One of the heat exchangers in the air conditioner could get damaged if the condensation and evaporation system is set higher than what is ideal.

Flashing indicators

The decision to use an error reporting system with flashing LEDs in General Climate air conditioners is hard to understand. Most likely as a result of the owners’ tendency to focus on the blinking at once rather than the message displayed on the remote controller. The names of the blinking indicators must be noted in order to identify the error name based on their combination in order to interpret the data.

Error coding uses the following four indicators: "DEF/FAN," "WATER ALARM," "OPERATION," and "TIMER." The LEDs have two modes: constant on and flashing between 3 and 5 Hz.

The mistakes are listed according to how critical the event was, descending:

1. OPERATION and TIMER flashes. EEPROM memory integrity is broken. The cause may be vibration from the fan operation or a voltage surge that broke through the filter of the air conditioner PSU. The problem is eliminated by installing a new original board from General Climate and "filling" the firmware.
2. Three indicators flash at once: "OPERATION" + "TIMER" + "DEF/FAN". The problem may be in the air conditioner power supply unit, General Climate system was charged with dirty refrigerant or too many chips have accumulated in freon, which are not caught by the filtration system.
3. If only OPERATION is flashing, the problem is a short circuit on the evaporator temperature sensor. Sometimes General Climate air conditioners leave this state by themselves and continue to work. It is necessary to change the sensor, otherwise the next time the short circuit (error) may lead to an air conditioner failure.
4. DEF/FAN in some models PRE/DEF. Error indicates damage to the temperature sensor on the heat exchanger-condenser. Also need to be replaced with a similar unit from General Climate.
5. The WATER ALARM LED is lit (not flashing). The error indicates that the float is mechanically frozen. The cause may be dirt or improper installation of the air conditioner. It is possible to start if you hit lightly on the container with drainage water.
6. If the WATER ALARM LED is flashing, the cause of the error is excessive condensation in the drain chamber. It means that the water drainage system of the air conditioner obviously cannot cope with its removal. For example, a clogged pipe.

If the split-system General Climate is turned off for thirty minutes, the majority of the listed errors can be reset. The oil will drain into the compressor sump during this period, condensate will drain, and the capacitors on the board will discharge. It is not possible to permanently reset errors in this manner because the cause of the air conditioner’s blockage remains unknown. Maintaining, flushing, refueling, and attempting to swap out the control board for a known functional one are all essential.

General Climate ASTRA 07-36 split-systems errors

Reviews indicate that one of the effective models makes use of a combined error reporting system. An alphanumeric code representing information about issues with the external unit appears on the screen:

• F0 – emergency situation, perhaps the refrigerant has "escaped" through a defect on the soldered joint or the current on the compressor winding has exceeded the norm several times during an hour (possibly jamming);
• F3 – malfunction of outside air temperature sensor;
• F4 – non-working sensor on the external pipe;
• F5 – failure of the pressure sensor on the high-pressure pipe of the compressor;
• C5 – compressor is shut down by protection due to overcurrent in compressor wiring;
• E5 – compressor voltage is higher than normal;
• E6 – no communication with the indoor unit;
• U8 – operation failure due to a break with the control board.

Errors in the outdoor air conditioner unit’s operation can be reported using the alphanumeric code shown on the control boards. Either a series of flashing LEDs is used to code each error. The LEDs are labeled "COOL" and "OPERATION".

Vital! The inability to distinguish which air conditioner indicator is blinking is one of the circuit’s quirks. One needs to count the number of flashes that occur between pauses. Older General Climate air conditioners typically had this kind of design.

Code system for indoor apparatus:

1. F1 – air temperature sensor is not working. Indicator "COOL" gives out 1 flash with a pause of up to 10 seconds.
2. F2 – sensor on the pipe of the indoor unit-module is damaged. "COOL" blinks twice every 10 seconds.
3. E1 – stoppage due to high-pressure sensor actuation. OPERATION" flashes once with a pause of 10 sec.
4. E2 – Heat Exchanger Frosting. OPERATION" diode gives a packet of two flashes every 10 sec.
5. E3 – stop due to severe pressure drop at compressor inlet, "OPERATION" flashes three times.
6. E4 – temperature exceeded on high pressure heat exchanger, LED blinks four times.
7. H6 – fan does not start.

When installed and refueled correctly, General Climate ASTRA 07-36 air conditioners typically function flawlessly. Poor or nonexistent service quality is often the cause of problems.

Error indication of STANDART 30-36 General Climate units

In this model, the number of LED flashes on the board codes information about issues and errors on the external unit. A single flash suggests that there is an issue with the indoor air conditioning module. An issue with the tube’s thermistor is indicated by double blinking.

An error in the air conditioner compressor’s operation is indicated by a batch of three flashes. A sharp rise in refrigerant pressure is the cause.

An issue with the external unit’s connection to the power system is indicated by four flashes.

Blinking five times indicates an unestablished communication channel between the modules and the board.

The air conditioner’s indoor unit’s error codes are indicated by flashing "OPERATION," "Timer," "Defrost," and "AUTO" indicators.

The General Climate control system functions flawlessly when "OPERATION" is lit (not flashing) and other LEDs are off. A power supply issue is present if "OPERATION," "Timer," and "Defrost" are flashing while "AUTO" is not functioning. Too many current surges are happening. The room air control’s external thermistor is the source of the error if only the "Timer" blinks.

If the sensor isn’t working properly or if all other indicators are "silent" and only "OPERATION" flashes, the high-pressure pipe’s pressure is off. The most complicated situation is a microprocessor error. To indicate it, the "AUTO" indicator blinks repeatedly.

Error codes of S-HR series split-systems

Split systems in the General Climate air conditioner line have cooling capacities ranging from 7 thousand BTU to 36 thousand BTU. Among the S-HR series are:

• S07HR S09HR – with minimal cold performance;
• S12HR, S18HR – medium cooling capacity (room area up to 50 m 2 );
• S24HR, S30HR, S36HR – large cooling capacity, the area – 80m 2 and more.

An LED error reporting system is employed for the entire "S-HR" series. LEDs are used as the "OPERATION," "TIMER," "DEFROSTING," and "AUTO" indicators.

General Climate models 07, 09, 12, and 18 air conditioners use a single error coding scheme; the "AUTO" indicator is not used.

Since the Model S24HR General Climate can be linked to a 380 V network, the code also employs the "AUTO" indicator:

• if blocking has occurred due to exceeding the input current limit, all four LEDs flash;
• indoor unit sensor (indoor air temperature) is damaged, only LED-diode "TIMER" will blink;
• the sensor on the input (cold) line is malfunctioning, only the "OPERATION" LED flashes;
• The temperature sensor of the external unit does not work – only "DEFROSTING" flashes;
• If the protection has switched off the external unit due to overheating or overpressure, "DEFROSTING" and "AUTO" will flash simultaneously.

If the S24HR General Climate’s "AUTO" indicator is blinking while the others are not lit, things are dire. This suggests that the problem is with the EEPROM memory, and it is impossible to fix the air conditioner on its own without a specialist.

There are a few more General Climate error codes for the older S30HR and S36HR models of air conditioners.

Fault codes of three-phase air conditioners

An indicator scheme consisting of three LEDs (LED1, LED2, and LED3) on the unit panel is employed to provide information regarding improper operation of the General Climate split system.

Three-phase models with a cooling capacity of up to thirty thousand BTU use the following scheme for error reporting:

1. LED3 on, others off. The air conditioner works in normal mode, without failures.
2. LED1 and LED3 are on, the others are off, means that the phases are incorrectly connected at the input of the air conditioner PSU.
3. Only LED2, LED3 are lit. The air conditioner is switched off due to overload on input current limit.
4. All LEDs are lit. At least one of the phases is skewed or broken.

A cooling capacity of 30,000 BTU is equivalent to approximately 8 kWh of power consumption. Therefore, when you turn on the air conditioner, you might receive an error message in addition to a minor issue with the refrigerator or microwave oven if you connect the air conditioner to the network incorrectly.

The information scheme for General Climate air conditioners with higher power (above 30 thou BTU) looks like this:

1. LED1 is on flashing, the others are off – wrong phase connection to earth connection.
2. LED1 and LED2 are blinking, LED3 is inactive. Compressor protection tripped due to overpressure in the cold heat exchanger.
3. LED3 is blinking, the others are inactive. The permissible input current has been exceeded.
4. LED3 and LED2 are on, LED1 is inactive. External heat exchanger overheating.
5. LED2 is on, the others are inactive. The sensor reading the temperature of the street air does not work.
6. All three LEDs are blinking – overheating of the heat exchanger on the indoor unit.

Clearly, the provided plan is intended for General Climate air conditioners that are either new or in need of maintenance. Fouling of heat exchangers and sensors must be allowed for in split systems with extended service lives.

Understanding General Climate air conditioner error codes is essential for effective maintenance since decoding and troubleshooting become vital. Each code denotes a distinct problem that helps identify issues with the system. Users can identify possible issues and conduct efficient troubleshooting by deciphering these codes. By interpreting these codes, users can promptly address issues such as communication errors, malfunctioning sensors, or system overload, thereby ensuring optimal performance and longevity of their air conditioning units.

For the purpose of troubleshooting common issues that may arise during operation, it is imperative to comprehend the error codes on General Climate air conditioners. Through the process of deciphering these error messages, homeowners are able to determine the underlying cause of the issue and implement the necessary solutions.

E1, which denotes a communication error between the indoor and outdoor units, is one of the most frequently encountered error codes. This might be the result of a bad wire or connection. Homeowners can frequently fix this problem without hiring a professional by inspecting the connections and making sure they are secure.

E2, which indicates a problem with the indoor unit’s temperature sensor, is another commonly occurring error code. This could happen if the sensor’s ability to precisely detect the room temperature is compromised by dirt or damage. This problem can be resolved by cleaning the sensor or, if needed, replacing it, which will allow the air conditioner to operate normally again.

Another error code that homeowners might run into is E4, which denotes an unusual variation in voltage or frequency. This might be the result of power supply fluctuations or problems with the home’s electrical system. In these situations, it’s critical to get in touch with a licensed electrician to identify and resolve the root of the issue.

Homeowners can more successfully troubleshoot common problems with their General Climate air conditioners by becoming familiar with these error codes and their meanings. To guarantee the correct operation and longevity of their cooling system, it is best to seek assistance from a qualified HVAC technician if the issue continues or if they are unclear of the next steps.
