Hello! If you’re reading this, your Kaysun air conditioner is likely displaying the E3 error code, and you’re looking for a solution. Don’t worry; we’ll guide you step by step on what this error means and how to fix it without becoming an expert technician.
What is the Indoor Ambient Temperature Sensor?
Before diving into the solution, let’s talk a bit about what this sensor is. The indoor ambient temperature sensor is a small device that measures the room’s air temperature. The air conditioner uses this information to adjust its operation and maintain the temperature you’ve selected. If there’s something wrong with this sensor, the air conditioner can’t function properly.
Steps to Resolve E3 Error
- Verify Sensor Connection
- Turn off the air conditioner: Before doing anything, make sure the air conditioner is turned off to avoid any electrical risk.
- Locate the sensor: Refer to your air conditioner’s manual to find where the indoor ambient temperature sensor is located.
- Check connections: Once you find the sensor, verify that it is properly connected. Sometimes, the E3 error can simply be because the sensor has become disconnected or the wires are loose.
- Clean the Sensor
- Gentle cleaning: If the sensor is dirty, it may give incorrect readings. Clean it gently with a dry cloth, ensuring there is no dust or dirt obstructing it.
- Restart the Air Conditioner
- Disconnect and reconnect: After verifying and cleaning the sensor, disconnect the air conditioner from the power, wait a few minutes, and reconnect it. This may reset the system and resolve the error.
- Consider Replacing the Sensor
- Sensor replacement: If, after cleaning and checking connections, the E3 error persists, the sensor may be damaged and need replacement. In this case, it’s best to contact a professional technician or follow your manual’s instructions to replace the sensor yourself.
What if Nothing Works?
If you’ve followed all the steps and the E3 error code continues to appear, there might be a more serious issue with the main circuit board (PCB) of your air conditioner. In this case, we recommend contacting a professional service technician to help you troubleshoot and fix the problem.
