E1 indicates an issue with the furnace’s high limit switch, E2 indicates an issue with the furnace’s flame sensor, E3 indicates an issue with the furnace’s fan limit switch, and E4 indicates an issue with the furnace’s pressure switch.

Other common Carrier furnace error codes include E5, E6, and E7. E5 indicates an issue with the furnace’s combustion air pressure switch, E6 indicates an issue with the furnace’s exhaust pressure switch, and E7 indicates an issue with the furnace’s inducer motor.

Finally, error code E9 indicates an issue with the furnace’s control board, and error code E10 indicates an issue with the furnace’s blower motor. It is important to note that these are just a few of the most common error codes, and many more can arise depending on your furnace’s model and age.

How to Troubleshoot Carrier Furnace Error Codes

If your Carrier furnace displays an error code, the first step is to determine which code it is. In many cases, the code will appear on the furnace’s LED display, but if not, you can find the code in the furnace’s user manual or by searching online. Once you have identified the code, you can begin troubleshooting the issue.

The first step is to ensure that all the connections to the furnace are secure and that all the safety systems are functioning properly. This includes checking the furnace’s pressure switch, high limit switch, flame sensor, fan limit switch, combustion air pressure switch, exhaust pressure switch, inducer motor, control board, and blower motor. If any of these components are not functioning properly, you may need to replace them.

If none of the components are faulty, then you may need to reset the furnace. To do this, you will need to turn off the furnace and disconnect the power for at least 30 seconds. After this, you can turn the furnace back on, and the error code should be cleared.
