Simple Steps To Reset A Chigo Air Conditioner

We use air conditioners to keep our homes more pleasant throughout the hot, sticky summer. Currently, these units are seen as necessities rather than just a luxury.

An air conditioner has incalculable advantages for our homes, health, and overall well-being. But what should you do if your Chigo AC unit fails unexpectedly and requires resetting?

You need to perform some analysis and troubleshooting in order to reset your Chigo air conditioner. However, you must first know the various error codes and what they mean. How this can assist in resetting your air conditioner is also explained.

When a modern appliance, like the air conditioner, malfunctions, it is frustrating. We typically try to solve these problems on our own.

What if we can’t get it to reset? Where can we locate reliable information? Continue reading as we discuss each of the aforementioned problems in detail and provide suitable solutions.

Error Codes For Chigo Air Conditioners

Another quick fix for most Chigo air conditioner problems is to check the error number and focus on the problem it suggests.

The various AC fault codes for DC Inverter Split Type are shown below:

Chigo DC Inverter Split Type A/C Error Codes

1. F1 – Stands for Communication Error.

Additional clue: The indoor digital tube may display F1 while the outdoor LED flickers 15 times.

For three minutes straight, no data was transferred between the two devices. The voltage regulator could be broken, the communication line could be loose, or the connections connecting the two devices could be misconnected.

Troubleshooting:

• Check to see that the connection between the internal and exterior equipment is accurate. If not, make changes and run another test.
• Check for loose PCB inserter pieces and tighten them.
• Check to determine if the outdoor PCB’s AC voltage is alright if the fuse has blown out or come free.
• Replace the outer PCB if everything above works out as intended.

2. F2 – Stands for Indoor Temperature Sensor Error

In this case, the sensor wire can be loose or attached incorrectly. Damage to the temperature sensor is another possibility.

Solution:

• Check for any frayed sensor wires. Find any loose sensor wires and, if necessary, repair them.
• Ascertain the resistance. Examine the temperature sensor’s resistance (first remove it). If there is an open circuit, a short circuit, or an abnormal value, the sensor could experience issues. Even worse, if the sensor is damaged, it could need to be replaced.
• Modify the PCB inside. If everything appears to be in order, change your indoor PCB.

3. F3 – Stands for Error from the Coil Temperature Home Sensor

The sensor wire may once again be severely frayed or damaged. The second option is that there is a problem with the temperature sensor itself.

Methods for troubleshooting:

• Retry the steps we highlighted for error code F2.

4. F4 – Stands for Indoor Fan Issue

This suggests that the feedback pulse signal is not being produced by the interior fan after 30 seconds. The fan will consequently stop.

Methods for troubleshooting:

• Test of voltage output. Turn on the gadget to begin. At the appropriate indoor terminal, check the output voltage. If there is no voltage, the indoor PCB needs to be changed.
• Instead, try out your resistance. Remove the connection to the indoor fan’s motor and test it if the electrical resistance of the winding is unacceptable; if it is not, the fan motor should likely be replaced.
• Install a new indoor PCB if changing the fan motor is useless.

5. F5 – Stands for Defective Outdoor Module

The problem could be coming from the external PCB and drive circuit.

Methods for troubleshooting:

• Make sure all of your contacts are correct. Now check to see if the connection (6 cores) between the main external board and drive module of those devices is correct and make any necessary repairs.
• Replace the drive board. If it has been verified that the main board is in good shape, think about replacing the outside drive board.

6. F6 – Stands for A Problem with the External Temperature Sensor

Given that the outside air temperature is at or above 20 °C, this may be the case.

Techniques for troubleshooting:

• Verify any sensor wires for fraying. Inspect the sensor wire for looseness and make any necessary repairs.
• Look into the opposition. Make sure the resistance of the temperature sensor is accurate (first remove it). If there is an open circuit, a short circuit, or if the value is abnormal, there can be problems with the sensor. It can even be necessary to replace the sensor due to damage.
• Modify the PCB inside. At this point, if everything appears to be operating normally, replace your exterior PCB.

7. F7 – Stands for Error with the Outside Coil Temperature Sensor

The outdoor coil’s temperature. The sensor may malfunction whenever the pipe temperature outside hits or exceeds 54°C or falls below 20°C.

Methods for troubleshooting:

• Verify there are no unsecured sensor wires. A slack sensor wire could be the source of this and other sensor problems. Observe, and if required, correct.
• Look at the resistance. If this doesn’t solve the problem, try the previously described resistance test on the temperature sensor and replace it if necessary.
• Search for any missing or harmed components. If the sensor is working properly, the issue may be due to a component in the associated integrity circuit being missing or damaged. Verify each component and replace any that are broken or missing.

8. F9 – Stands for Error with the Outside Coil Temperature Sensor

If the compressor discharge temperature is below 0°C or above 120°C, the issue frequently arises.

Methods for troubleshooting:

• Re-do the troubleshooting procedures for the F7 issue.

9. FC – Stands for Atypical Compressor Driving

There’s a chance the compressor isn’t working properly.

Methods for troubleshooting:

• Look over the tying wire. On the main drive board, check the condition of the connecting wire and, if necessary, repair or replace it.
• Look at the screws. Examine each screw to make sure it is firmly attached to the main drive board, and replace any that are not.

Reminder: When tightening the screws, avoid crushing the module.

• Look over the voltage. Verify the input voltage of the drive module to ensure it is accurate (check your manual for accurate input voltage). The controller must be replaced if the voltage is actually incorrect.

If not, you might need to replace the drive module or the complete board (if there is only one board) (for Chigo ACs, where the outdoor controller is separate from the drive module).

10. FF – Stands for Issues With Different Chigo Air Conditioners

Your split Chigo air conditioner may also be experiencing one of the issues described below if the error code FF appears.

• Unreasonably large amounts of refrigerant If your appliance doesn’t have enough refrigerant inside, it could malfunction. A potentially dangerous situation would be if the weld were to leak or become blocked. Decreased pressure throughout the entire system is another indication.
• If the four-way valve appears to be malfunctioning even though the refrigerant appears to be in fine condition, check to see if it is and replace it as necessary.
• Faulty PCB; after replacing it with adequate refrigerant, the valve looks to be in acceptable condition.

Dos And Don’ts For Chigo Air Conditioner

DO: To keep the air conditioner in good working order for as long as possible, adhere to the maintenance recommendations in the manual.

DO: Before doing any Chigo air conditioning repair procedures, turn off the unit’s power supply.

Don’ts: Avoid often activating the compressor, no more than five times each hour, as this can reduce the lifespan of the air conditioner.

Don’ts: When cleaning the complete unit, stay away from using solvents like benzene since they may cause button dysfunction or discoloration.

We should also emphasize that the only effective way to clean a towel or cloth is to soak it with water or a mild cleaning agent.

Other Frequently Detected Faults

Below is a list of common issues people have with their Chigo air conditioners, along with solutions for each.

Your AC’s Compressor Occasionally Stops Working

• It is recommended that you clean the compressor every summer.
• Before adding refrigerant, check the coolant level and top it off. If you’re unsure about the steps, you might want to consult a specialist.
• Check the thermostat’s settings and make any required modifications. Check for debris inside the device, clean the wiring, and, if necessary, inspect and fix the thermostat’s internal components.

Chigo Air Conditioner Won’t Turn On

• The fuse must be changed immediately.
• Replace the batteries or the controller.

The equipment will occasionally not work after a power outage because the data has been reset. If this happens to you, try starting it with the remote control; it usually works.

Chigo Air Conditioner Has No Heat

• Close the windows and doors now if you haven’t already.
• If the coolant is leaking or not being charged adequately, look for leaks and appropriately charge it.

Keep in mind that if the outdoor temperature falls below a particular threshold, this could also happen.

Despite Having Consistent Airflow, Your Chigo AC Isn’t Adequately Cooling

• Adjust the temperature properly.
• The appliance’s heat exchanger should be cleaned.
• Remove the air filter and clean it.
• Any windows and doors that are left open must be locked.
• Put up drapes to keep the sun’s rays out.
• Streamline the heat where it originates.
• Check for leaks and re-charge the refrigerant as directed.
