Understanding the E5 Error Code
When your Carrier air conditioning unit flashes the E5 error code, it’s a red flag indicating that an internal sensor has reported a value outside the expected normal range.
This diagnostic indicator is generated by the system’s control board, signaling that something is amiss within the unit. The E5 error code serves as an internal notification that the system isn’t functioning within its ideal range and requires attention before normal operation can resume.
As you troubleshoot the issue, remember that the control board plays a vital role in monitoring and regulating the unit’s performance. Understanding the E5 error code is vital in identifying the root cause and taking corrective action to restore your Carrier AC unit’s ideal performance.

Causes of the E5 Error on Carrier AC Units
The E5 error code on your Carrier air conditioning unit can stem from various factors, all of which you’ll need to ponder as you troubleshoot the problem.
One likely cause is a faulty thermistor, a temperature-sensing component that’s critical to your air conditioner’s operation. A malfunctioning thermistor can disrupt the unit’s ability to regulate temperature, resulting in the E5 error.
Another possible cause is a refrigerant leak, which can also trigger the E5 error code. You must determine and address the root cause of the issue to prevent further damage to your Carrier air conditioner.
