How to Deal with Coleman Furnace Error Codes and Issues

Do you find your furnace making weird noises? Does it turn on and off at random intervals? Or does it simply not turn on at all? Perhaps the light is also flickering. If so, you are likely having issues with your furnace. While some issues may be minor and can be fixed with a simple adjustment, others may require more attention and repair. Fortunately, most heating systems are equipped with indicators to alert homeowners of any problems or imminent issues. If you have a Coleman gas furnace, however, these indicators may seem a little different than what you’re used to seeing. Because of this, we’ve got some helpful tips for dealing with common error codes and other issues related to your new (or old) furnace!

Error Code 16

One of the most common and potentially dangerous errors that your furnace may produce is error code 16. When this error occurs, it means that your furnace cannot produce a flame. If you see this error code, you should shut off your furnace immediately and call a professional. While some minor adjustments and cleaning may be able to fix it, the source of the problem may be much more complex. If the issue is not addressed immediately, the furnace could cause damage to other systems in your home, including the duct system.

Error Code 24

Error code 24 indicates that your furnace may not be getting any power. If you are using a gas furnace, power outages can be an issue. However, if you have a furnace that is powered by electricity, you will likely see this error code. When this happens, it means that there is an issue with the wiring in your home. This could be a minor issue, such as a loose wire or connection. Alternatively, it could be something more significant, such as a short circuit.

Error Code 33

Error code 33 means that there is a problem with the heat exchanger of your furnace. This usually means that there is a clog or obstruction in the furnace pipe. If you see this error, it is best to call a professional. There may be something that is able to be cleaned or adjusted to fix the issue. If there is a more serious problem, you may need the assistance of a heating technician.

Error Code 34

Error code 34 indicates that there is a problem with the gas pressure in your system. If you see this error code, it is a good idea to check your furnace filter to make sure it is clean. This may be all that is needed to fix the issue. If not, you may want to call a professional. A clogged filter or blocked flow can cause a drop in pressure. This can lead to other issues, so it is best to get it checked out as soon as possible.

Error Code 35

Error code 35 indicates that the flame sensor of your furnace is not working properly. This sensor is designed to turn off the furnace if it detects a flame. If this sensor is not working properly, it could lead to an increase in carbon monoxide levels in your home. It is important to address this error as soon as possible.

Error Code 38

Error code 38 means that the humidifier control wire is not functioning properly. This wire is designed to turn on the humidifier when needed. If the furnace does not sense the proper amount of humidity in the air, it will turn on the humidifier. If this error occurs, you may need to replace the wire or humidifier.

Error Code 42

Error code 42 means that there is an issue with the motor that turns on your furnace blower. This usually indicates that the motor has overheated. If this error occurs, you should shut off the furnace and unplug it. You can then check the blower and motor to make sure they are free of debris or other contaminants. If not, you can clean them or replace them as needed. You may also want to get your furnace checked out by a professional to make sure there isn’t a more serious issue.

Error Code 44

Error code 44 indicates that there is a problem with the flame sensor in your furnace. This sensor is designed to turn off the furnace if it detects a flame. If this sensor is not working properly, it could lead to an increase in carbon monoxide levels in your home. It is important to address this error as soon as possible.
