How to eliminate E2 error in Kaysun air conditioning?
- Error: E2
- Description: Open circuit or short circuit in the temperature sensor T1 – Communications failure between the inner IC and the outer IC – the temperature sensor does not work or there is a short circuit.
- Solution: Contact your service representative.
If you have a Kaysun air conditioner and you have encountered the E2 error, do not worry, here we will explain what this error means and how to fix it.
What is the E2 error in a Kaysun air conditioner?
The E2 error is an indication that there is a problem in the T1 temperature sensor, it could be an open circuit or short circuit in the sensor, a communications failure between the indoor IC and the outdoor IC or that the temperature sensor is not working properly.
What are the causes of the E2 error?
The causes of the E2 error can range from a fault in the temperature sensor to a problem in the communication between the air conditioner components. There may also be a short circuit in the electrical circuit of the temperature sensor.
How to solve the E2 error in a Kaysun air conditioner?
The solution to this problem is to contact Kaysun technical service. It is important not to try to repair the problem yourself, as it can be dangerous and you may also lose the warranty of the equipment.
Kaysun’s technical service has highly trained personnel to solve any problem you may have with your Kaysun air conditioner, including the E2 error.
If you have the capabilities to try to solve the error and following the necessary safety measures, you would like to solve the E2 error in your Kaysun air conditioner. Below, I provide you with a possible solution that you can follow at your own risk and responsibility:
- Turn off the air conditioner: before starting any repair, turn off the unit and disconnect the power cord.
- Locate the T1 temperature sensor: the T1 temperature sensor is located in the evaporator of the air conditioner. You can locate it by consulting your owner’s manual or by searching online for the location of the sensor on your specific model.
- Check the temperature sensor: Check the T1 temperature sensor for any damage to its housing or the wires connected to it. If the wires appear damaged, cut or frayed, you will need to replace the sensor.
- Check the communication between the indoor and outdoor ICs: check the wires connecting the indoor and outdoor ICs, making sure they are firmly connected. If the wires are damaged, they should be replaced.
- Check the electrical circuit: check the electrical circuit of the T1 temperature sensor for shorts. You can use a multimeter to measure the resistance of the sensor to check if there is a problem with the electrical circuit.
- Replace the temperature sensor: If the T1 temperature sensor is damaged or if there is no resistance in the sensor’s electrical circuit, you will need to replace the sensor. Purchase a replacement temperature sensor compatible with your Kaysun air conditioner model and install it following the instructions in the owner’s manual.
- Test the air conditioner: once you have replaced the T1 temperature sensor, turn the air conditioner back on and check if the E2 error has disappeared. If the error persists, it is possible that there is a more serious problem in the equipment and you should contact Kaysun technical service for a more advanced solution.
If you have a Kaysun air conditioner and you have encountered the E2 error, do not try to fix it on your own. Contact Kaysun service and let them take care of the problem safely and efficiently. Remember that safety comes first and that any improper repair can have serious consequences.
