Goodman Furnace Error Codes: What Are They and How Can You Fix Them?

Did you know that the Goodman furnace error codes are a series of alerts that come from your furnace’s sensors? These alerts identify common problems with your system, so you can take the necessary action to correct them. When you get a new or used furnace, it is helpful to know the different error codes so that you can troubleshoot and fix any issues. Knowing these codes also makes it easier for a technician to diagnose and repair any issues with your furnace. There are multiple types of error codes that will appear on your control panel as well as an alert light if there is an issue with the control board or sensors. If you see one of these codes, don’t worry—there are ways to fix them!

What does a Goodman furnace error code look like?

The Goodman furnace error codes will show up as either an “E” or an “F” followed by a number. The letters “E” or “F” indicate whether the error is related to the control board or sensors. The number indicates which sensor is causing the issue. So, if you get an error code F6, that means there is an issue with the sixth sensor. The error codes will show up on your thermostat, as well as a small indicator light that is found on the control panel. The error codes will usually appear as one of the following: E1: High limit control circuit fault E2: Inverter circuit fault E3: Ignition circuit fault E4: Blower circuit fault E5: Sensor circuit fault E6: Overload/blocked filter fault F1: Temperature sensor fault F2: Board fuse fault

Error Code 49

This error code means that the furnace has detected a problem with the blower wheel. The blower wheel is what spins and blows air through the system, so if it is broken, it can’t do its job. A bad blower wheel will cause the furnace to shut down immediately, so you’ll know that there is an issue right away. This can be caused by a variety of issues, including a bend in the wheel or a loose or bent shaft. You can fix this issue by replacing the blower wheel.

Error Code E1

If you see this error code, it means that there is an issue with the high limit control circuit. This is an important part of the furnace, as it senses heat and turns off the furnace if it gets too hot. A faulty high limit control circuit can create a dangerous situation, so it is important to get it fixed as soon as you can. There are a few reasons why this error code would appear, including a short in one of the wires, a loose connection, or a broken sensor. You can fix this error by checking the wires for damage and tightening any connections.

Error Code E3

An error code E3 means that there is an issue with the ignition circuit. This circuit is what sparks the furnace to life when the thermostat tells it to heat up. There are a couple of reasons why you would see this error code, including a bad circuit board or a broken wire. You can fix this error code by checking the circuit board to make sure that there are no loose connections and that none of the wires are broken.

Error Code E4

If you get an error code E4, it means that there is an issue with the blower circuit. The blower circuit moves air through the system so that your furnace can heat the house. There are a few reasons why the blower circuit would be faulty, including a faulty board, a broken wire, or a broken sensor. You can fix this error by checking the circuit board for loose connections and broken wires. You can also check the sensors to make sure that they are intact.

Error Code E6

An error code E6 means that there is an issue with the overheat/blocked filter circuit. The overheat/blocked filter circuit is what tells the system when the filter is clogged or if the system overheats. This means that the furnace might shut down so that it doesn’t get too hot and cause a fire. This can be caused by a clogged filter or a broken sensor. You can fix this error by cleaning the filter and checking the sensors to make sure that they are intact.

Error Code F1

If you see an error code F1, it means that there is an issue with the temperature sensor. This is the sensor that measures the temperature in the house. This sensor is critical for regulating the operation of the furnace, so if it is faulty, the furnace won’t work properly. A faulty temperature sensor can be caused by a broken wire or a broken sensor. You can fix this error code by checking the wires for damage and the sensor to make sure that it is intact.

Error Code F2

An error code F2 means that there is an issue with the control board. The control board is what powers the furnace and lets it know what to do. If there is an issue with the control board, the furnace won’t work properly. There are a few reasons why the control board would be faulty, including a bad fuse or a broken wire. You can fix this error code by checking the fuse to see if it is blown and replace it if necessary. You can also check the wires to make sure that they are intact.

Final Thoughts

The Goodman furnace error codes are a series of alerts that come from your furnace’s sensors. These alerts identify common problems with your system, so you can take the necessary action to correct them. When you get a new or used furnace, it is helpful to know the different error codes so that you can troubleshoot and fix any issues. Knowing these codes also makes it easier for a technician to diagnose and repair any issues with your furnace.
