- 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.
