A Guide on What to Do When Your Furnace Error Code Doesn’t Work

In the coldest and darkest of winters, your furnace is going to be something you are going to need more than ever. However, with any kind of machinery, there will be times when it breaks down. Fortunately, in most cases, you can troubleshoot these issues from home with an error code. If you have a furnace that has an error code, don’t panic! This common issue is a good thing. It means that your furnace has multiple safety precautions built into it in case something goes wrong. However, not all error codes are the same and some require immediate attention while others can wait until another time. In this blog post, we’ll explore what different error codes mean for your furnace and how to troubleshoot them if they happen to you.

What does an error code mean?

The furnace’s error code is a way for the equipment to tell you what kind of problem it’s having. This will help you decide how to move forward. Usually, the error code will be displayed on a screen on the front of the furnace and you can reference the error code manual to see what the code means and how to troubleshoot it. If your furnace is older and doesn’t have a digital screen, you may see error codes written on a card or sticker inside the furnace. Just like with any other piece of machinery, it’s important to know what your error code means. If you have no idea what the error code means, you can likely find help online.

Furnace pressure issues

Furnace pressure issues are usually indicated by an error code of OE-E or a flashing error code of E-O. If your furnace is experiencing pressure issues, it may not be able to produce enough heat or it may run for a shorter length of time than normal. When the furnace pressure is too low, the pilot light is unable to stay lit. The furnace’s error code is telling you that there is a problem with the pressure and that you’ll need to fix it. You can check your furnace’s pressure by opening up the pressure gauge on top of the furnace and seeing if the needle falls somewhere between 8 and 12 PSI. Cleaning or replacing filters and parts as needed can help you fix pressure issues. If you’re experiencing pressure issues, it’s best to have an experienced furnace repairman come to your home to inspect and correct the problem.

Furnace circuit board failure

A furnace circuit board failure is usually displayed as an error code of CO. A furnace circuit board failure occurs when the furnace’s circuit board stops working and can’t transmit power to other parts of the furnace. If your furnace’s circuit board has failed, you’ll likely have other error codes as well. While you can try to troubleshoot the circuit board failure by replacing the circuit board and resetting the furnace, it’s best to have an experienced furnace repairman look at it for you. When the circuit board fails, it puts the entire furnace at risk. Because the furnace is no longer receiving power from the circuit board, you need to reset it manually. Follow the furnace’s instructions on how to reset it to avoid additional problems down the line.

Furnace blower motor issues

A furnace blower motor issue is usually indicated by an error code of EB. A blower motor issue means that the motor that blows air through the furnace is having some kind of problem. A furnace blower motor issue may cause the furnace to turn off early or it may run too long. Blower motor issues can be caused by a clogged motor, faulty wiring, or a faulty motor control board. If your furnace blower motor is having issues, it’s important to have it looked at right away. Furnace blower motor issues can lead to more serious furnace problems if they aren’t taken care of right away.

Furnace burn-out and oxidation

A furnace burn-out and oxidation error code are usually indicated by an E06 error code. A furnace burn-out and oxidation issue mean that the burners inside the furnace are deteriorating and are close to failure. Burn-out and oxidation can be caused by several different things, including low maintenance, high usage, or poor fuel. If your furnace is experiencing burn-out and oxidation, you’ll want to replace the furnace as soon as possible.

Furnace control panel failure

A furnace control panel failure is usually indicated by an error code of E03. A furnace control panel failure means that the control board has stopped working and can’t be reset. The control board is responsible for turning the furnace on and off, so without it working, the furnace won’t be able to function properly. If you have furnace control panel failure, you’ll want to have the furnace replaced as soon as possible. While you can try to troubleshoot the control panel failure by replacing the board, it’s best to have an experienced furnace repairman do it for you.

Final words

The furnace is usually the first thing that people think of when they consider home comfort. However, with more than a hundred different brand names, a variety of different features, and even more reasons why your furnace might break down, it’s important to know what issues your furnace could have and how to troubleshoot them. If your furnace is having issues, it’s important to address them as soon as possible. Your furnace is responsible for keeping your home warm, and if it’s broken, you won’t be able to depend on it for that. In the worst-case scenario, a furnace issue can lead to carbon monoxide poisoning and even death. Make sure you know what issues your furnace might have and how to troubleshoot them from home.
