• Faulty or loose wiring between the units.
• Electrical or magnetic interference affecting the sensors.
• Overload or a short circuit in the electrical system.
• Obstruction or dirt in the air ducts.
• Damage or wear in the internal components of the units.

But you don't have much to worry about because, despite all these potential causes that may lead to your air conditioner experiencing issues, they all have a solution. So, let's take a look at what they are!

How to fix Carrier air conditioner Error E1?

To resolve the E1 error code on your Carrier air conditioner, you can follow the steps outlined below. Take note of each of them and don't skip any:

1. Turn off and disconnect your Carrier air conditioner from the power to reset the sensors: Sometimes, this simple solution can fix the problem. It may seem very basic, but it's worth a try. To do this, turn off your air conditioner completely and disconnect it from the power for a few minutes. Then reconnect it, wait for the indicator to signal that you can turn it on, and proceed with the appliance's activation. Check if the E1 error code has disappeared.
2. Check the wiring between the units and ensure it is well-connected and undamaged: If you find any loose, broken, cut, burnt, corroded, or scorched wires, you'll need to replace or repair them. This wiring must be in perfect working condition to ensure 100% operability of your air conditioner.
3. Move away any source of electrical or magnetic interference near your air conditioner: Sometimes, other appliances, mobile phones, or antennas can interfere with your air conditioner's operation because they can disrupt the sensors. Move all these devices away and check if the E1 error code has disappeared.
4. Ensure that the air conditioning ventilation ducts are not blocked or dirty: Regularly clean the filters and ventilation grilles to prevent the accumulation of dust, dirt, or residues that may hinder airflow. Sometimes, good preventive maintenance can be the solution to all problems that may arise in your air conditioner. Once you have finished cleaning, check if the E1 error code has disappeared.
5. Inspect the indoor and outdoor units and look for signs of damage or wear on internal components: Take advantage of performing preventive maintenance to check all critical components that, if functioning improperly, can cause problems in your air conditioner. Ensure that the compressor, fan, expansion valve, or condenser are in perfect condition. If you detect any issues, contact an authorized Carrier service technician for repair or replacement if necessary.
6. If the problem persists, please repeat all the previous steps and make sure to follow everything to the letter: Sometimes, multiple tests may be necessary to resolve the E1 error code. Don't get discouraged if you haven't identified the issue on the first attempt. We recommend repeating all the previous steps, but this time, ensure to do it more carefully and attentively. If the problem still persists, then it might be time to leave it to the experts.
7. Call an authorized Carrier service technician for a more thorough inspection: If none of the above steps has worked, the error may be more complex and require professional intervention. Please call Carrier technical support and schedule a home visit to have your air conditioner checked, receive an accurate diagnosis, and expedite the repair of your air conditioner.
