The Most Common Reasons for Armstrong Furnace Errors and How to Fix Them
When you live in a place where the temperature dips below freezing for most of the year, keeping your home warm and comfortable is no easy feat. You need a reliable furnace that’s going to keep things heating when there’s a chill in the air. However, even the best furnaces are prone to issues from time to time. You might experience an Armstrong furnace error code or something similar if your furnace is not operating properly. There are many different error codes that can appear depending on what exactly is going wrong with your system. When you see an error code on your furnace control panel, it means there is some type of issue with the appliance. Each code has its own meaning and potential solutions so you can fix it as soon as possible. Here are some of the most common reasons why you might see an error code on your Armstrong furnace and how to fix them.
Error Code F9
The most common error code for Armstrong furnaces is F9. This is a communication error between the control board and the motor. This can usually be fixed by making sure the wiring is all connected properly. If the wiring is not the problem, the control board may be bad and need to be replaced. Another potential cause of error code F9 is a dirty heat exchanger. When the exchanger becomes clogged with dirt and debris, it can’t function properly. You’ll need to clean the exchanger to avoid this issue. Finally, error code F9 can also indicate a problem with your thermostat. If the thermostat is set to the wrong temperature, it may not give your furnace enough power to run. The thermostat may need to be replaced if this is the case.
Frequent Cycling and Shudders
Frequent cycling is a common issue with furnaces. It occurs when the system is powering on and off repeatedly. This can cause your house to feel extremely uncomfortable, and it can significantly increase your energy bill. Frequent cycling can be caused by a few different issues with your furnace. A clogged filter, a dirty heat exchanger, or low refrigerant levels can all cause the system to cycle more often. The first two issues can be fixed by cleaning or replacing the problematic part. The third issue, low refrigerant levels, can’t be fixed until you call a professional to come out and change your system. This is an extremely dangerous job that should not be attempted by homeowners.
Error Code F7
Error code F7 is another common furnace error code. It means there is a problem with the blower motor. The motor’s bearings may be going bad, or the blower may be too clogged with dust and debris to work properly. If your blower motor is simply old and worn out, you can replace it. However, you may need to replace the motor if it is too clogged with dust and debris to function correctly. If the bearings in the motor are going bad, there is not much you can do to fix the problem besides calling a professional. If you continue to run the system with a bad blower motor, it can lead to major damage.
Error Code F6
Error code F6 means there is a problem with the control board. The wiring in the board may be loose, or the board could be overheating. If the wiring is loose, you simply need to tighten it up. If the control board is overheating, you may need to install a cooling fan. Simply place the fan near the control board, and it will help keep the temperature down. If you notice your furnace error code F6 is still present after trying these fixes, you may need to replace the control board. However, you may also have a different problem causing the error code.
Blower Doesn’t Turn On
If your furnace blower doesn’t turn on when the furnace is on, you have an issue. This can be caused by a few different things. Most commonly, the problem is caused by a clogged filter. If the filter is clogged with too much dust, it doesn’t allow enough air to flow through the furnace. This can cause the blower to fail to turn on. To fix this issue, simply clean the filter. You may also need to replace your filter if it is extremely dirty. Another potential cause of the blower not running is a loose connection in the heating system. A loose connection can cause the blower to short out and not turn on. To correct this problem, you need to check all of your connections and make sure they are secure.
Furnace Shuts Off Continuously
A furnace shutting off and on repeatedly can be a frustrating problem to deal with. After all, you want your furnace to stay on so you stay warm and comfortable. However, if it shuts off too often and for too long, you may be left in the cold. There are a few different reasons your furnace may be shutting off and on so frequently. An error code F6 or F7 may be causing the issue because the blower or fan is not working correctly. If the thermostat is not set correctly, the furnace may be shutting off because it doesn’t have enough power to keep running. You can fix this issue by checking your thermostat to make sure it is set correctly.
