Carrier Furnace Error Code 14: What You Need to Know
When your furnace goes into a diagnostic test or if it detects a problem when you turn it on, it will display error codes. These error codes help identify the issue with your system so that you can repair it and get back to a comfortable home as quickly as possible. A carrier furnace code 14 is an indication of an issue with the exhaust flue or chimney. Your furnace uses these flues to vent out hot air from the combustion process. When this error code appears, you need to take some steps to troubleshoot the problem and locate its source before something more serious occurs. Read our in-depth article on carrier furnace error code 14 below for more information and troubleshooting tips.
What Does Carrier Furnace Error Code 14 Mean?
A carrier furnace error code 14 means that the furnace has detected an issue with the flue. This is a serious issue that, if not addressed, may result in carbon monoxide buildup in the home. The flue is a pipe or tube that runs from the furnace to the outside of your house. It allows the furnace to release hot air that results from the combustion process. If the flue is blocked or has too many bends, it can result in a carrier furnace error code 14. There are several reasons that the flue may be blocked or have excessive bends. The most common culprits include leaves, pine needles, rodents, c-wire, and corrosion.
How to Fix Carrier Furnace Error Code 14?
There are several things that you can do to troubleshoot and repair a carrier furnace error code 14. The first thing that you should do is turn off the system and make sure that there is no visible blockage in the flue or chimney. Clear the flue of any obstructions. If you notice that the flue itself has excessive bends, reposition it so that it is less convoluted. You should also check the length of the flue. It should be at least 12 inches in length. When you’ve cleared the flue or replaced it with a new one, turn the system back on and see if the error code has gone away. If not, you may have a more serious issue.
Carrier F furnace error code 14: Flue is blocked
A carrier furnace error code 14: flue is blocked typically means that there is a significant blockage in the flue. This can be due to anything from leaves to a c-wire that got caught in the system during installation. The best way to address this issue is to remove the blockage and clear the flue. You can do this by climbing on a ladder, removing the flue, and cleaning it out. Do not use any tools to dislodge the blockage. Just use your hands.
Carrier F furnace error code 14: Flue has excessive bends
A carrier furnace error code 14: flue has excessive bends is typically caused by having the flue run through the wrong opening. The flue is supposed to run through the natural gas or fuel oil lines, not the wiring lines. If you notice that the flue is bent near the end, you can try and reposition it so that it is running through the gas lines again. If you can’t straighten it out, you can replace it with a new one.
Carrier F furnace error code 14: Flue is too short
A carrier furnace error code 14: flue is too short indicates that the flue is too short for the furnace. This can cause the furnace to overheat and can be potentially dangerous. If you notice that the flue is too short, you can try repositioning it so that it is closer to the furnace. If repositioning it is not an option, you can replace the flue with a longer one.
Carrier F furnace error code 14: Chimney has blockage or excess bends
If your furnace displays an error code 14: chimney has blockage or excess bends, it means that the chimney connected to the furnace is blocked or has excessive bends. The best way to address this issue is to remove the blockage and/or straighten the bend in the chimney. Again, do not use any tools to dislodge the blockage. Just use your hands.
Summary
If your furnace displays an error code 14, you should take it seriously and address the issue as soon as possible. The more time that passes after the error code appears, the more dangerous the situation becomes. If you have a carrier furnace, you can use the information in this article to help you troubleshoot and repair a carrier furnace error code 14.
