Carrier Air Conditioning Error E5

What is the fault of error E5 Carrier affecting your air conditioner?

If you have a Carrier air conditioner, you may have encountered the Error Code E5 at some point on the remote control display or the unit panel. This code indicates that there is a problem with the operation of the appliance and it needs to be addressed promptly.

Error Code E5 is often associated with a fault in the electrical wiring or excessive lack of maintenance in the air conditioner, especially in the condenser area. The condenser is the part of the system responsible for cooling the refrigerant circulating through the tubes, allowing the air to come out cold.

If the condenser is very dirty, obstructed, or damaged, the air conditioner will fail to cool properly, leading to an electrical overload that triggers the Error Code E5. But not all is bad news because this problem is fixable. Let's see what we can do to address this issue!

How to fix the error E5 of Carrier air conditioner?

Before panicking, you should know that there are some possible solutions you can try on your own to fix the E5 error code on your Carrier air conditioner. Take note of each and don't overlook any:

1. Turn off and disconnect your Carrier air conditioner from the power to reset the sensors: Sometimes, the E5 error code may be caused by a temporary sensor failure detecting the temperature and pressure of the refrigerant. By turning off and disconnecting the unit, the sensors are reset, and the error code is cleared. Wait a few minutes, then reconnect and turn on the air conditioner. Check if the E5 error code has disappeared, and if it persists, proceed to the next steps.
2. Check the electrical wiring of the air conditioner and make sure there are no loose, broken, or burnt wires: The E5 error code may also be due to a problem in the electrical wiring preventing the air conditioner from receiving the proper current and/or causing a short circuit. Using a multimeter, verify the continuity and resistance of the cables and replace any that are defective.
3. Clean the air conditioner condenser and remove any dirt or residue that may hinder its proper functioning: The condenser is a crucial component for air cooling, and if it is dirty or blocked, it can trigger the E5 error code. To clean it, turn off and disconnect the unit, remove the protective grille, and use a hose with pressurized water to wash the metal fins of the condenser. You can also use a soft brush or a vacuum cleaner to remove dust or leaves that may have accumulated. Dry it thoroughly before reinstalling. It's important not to use excessive force or pressure when cleaning to avoid bending the fins.
4. If the problem persists, please repeat all the previous steps and make sure to follow everything precisely: Sometimes, it may be necessary to perform multiple tests to resolve the E5 error code. Don't be 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 with attention to detail. If the problem still persists, then it might be time to involve the experts.
5. Call an authorized Carrier technical service 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 for them to inspect your air conditioner, provide an accurate diagnosis, and promptly repair your unit.

In conclusion, the E5 error code in Carrier air conditioners indicates a problem with the equipment's operation, typically related to the electrical wiring and/or the condenser. To resolve it, you can try the following solutions:

• Turn off and disconnect your Carrier air conditioner from the power to reset the sensors
• Check the electrical wiring of the air conditioner and make sure there are no loose, broken, or burnt wires
