Common Goodman Error Codes

Error codes on your Goodman air conditioner are indicators of specific issues within the system. Knowing what these codes mean can help you understand the nature of the problem and, in some cases, how to resolve it. Below are some common Goodman error codes you may encounter.

E4 Error Code

The ‘E4’ error code on a Goodman air conditioner refers to a problem with the unit’s outdoor temperature sensor. This sensor monitors the outdoor temperature to ensure that the air conditioner operates efficiently and within safe parameters. When you see the ‘E4’ code, it typically means that the sensor is either malfunctioning or has a poor connection.
