What Do the Kenmore Furnace Error Codes Mean?

‍

If you experience a problem with your Kenmore gas or electric furnace, you may receive an error code as a notification of the issue. Depending on the furnace model that you have, this code may be accompanied by an illuminated red light or another visual indicator to help you diagnose the problem. In general, these codes are universal for all types of furnaces. Each manufacturer may assign their particular meaning to each code, but they will generally mean the same thing across all brands. If your furnace experiences an error and begins displaying error codes, there are several ways to troubleshoot the problem and get it back up and running again as soon as possible. Read on to learn more about these codes and how to repair your appliance when these error codes appear.

Error Code 1 – Blower Problem

This is one of the most common furnace errors, and it is also one of the easiest to troubleshoot. Error code 1 typically indicates an issue with the blower motor, meaning that the motor is either clogged with debris or has failed. If the problem is with the blower being clogged, you can clean it out using a soft-bristled paintbrush or a vacuum. If the motor is overheated, it may be possible to replace it, but you will likely need to call a professional for this task since the motor is extremely heavy. If the blower motor is not the problem, there may be an issue with the wiring or the control panel. You will likely need a professional to diagnose and repair the issue in these cases.

Error Code 2 – Stuck Rotor

If your furnace experiences an error code 2, this may indicate that the rotor (a device used to control the furnace’s heat) is stuck. This can prevent the furnace from heating properly. If you experience this error code, you will likely notice that the furnace is not emitting heat. You may also notice a clicking sound coming from the furnace while running. You can rotate the rotor manually to repair this issue to get it unstuck. Frequently, this is a problem with a buildup of debris in the furnace. If this is the case, you may need to clean out the furnace and replace the rotor.

Error Code 3 – Electronic Failure

If you see error code 3, there may be an issue with the furnace’s control panel. This could mean that the wires are loose or broken or that the control panel components have failed. If you experience this error code, it’s important to turn off the furnace immediately. This is because the control panel may be sending false information to the rest of the furnace, leading to fire hazards. If the error code persists after turning off the furnace, you should call a professional to diagnose the issue and repair the control panel.

Error Code 4 – Combustion Problem

Error code 4 indicates a problem with the furnace’s combustion system. The most common cause of this issue is a buildup of soot inside the furnace. This can be caused by several factors, including improper installation, a dirty air filter, or a clogged exhaust system. If you experience this error code, you may notice that the exhaust system emits black smoke. You may also notice a burning smell coming from the furnace. If this is the case, turn off the furnace immediately and call a furnace repair professional.

Error Code 5 – Ignition failure

If your furnace experiences an ignition error, there may be a problem with the spark ignition system. This can be caused by several issues, including a dirty burner head, a broken or loose spark assembly, or short wiring. If you experience this error code, you may notice that the igniter is not engaging when you attempt to start the burner. You may also notice a burning smell coming from the furnace. If this is the case, turn off the furnace immediately and call a furnace repair professional. If the spark assembly and igniter are clean, it may be possible to tighten the screws and open up the wiring to make sure there are no loose connections. After these repairs, if the error persists, you will likely need a new ignition system.

Error Code 6 – Electronic Control problem

If your furnace experiences an error code 6, there may be an issue with the control panel. This could mean that the wires are loose or broken or that the control panel components have failed. If you experience this error code, it’s important to turn off the furnace immediately. This is because the control panel may be sending false information to the rest of the furnace, leading to fire hazards. If the error code persists after turning off the furnace, you should call a professional to diagnose the issue and repair the control panel.

Conclusion

Furnaces can experience several issues that will result in an error code on the control panel. These errors should be taken seriously, as they can lead to serious (and expensive) damage if left unchecked. If you experience an error code on your furnace, it’s important to troubleshoot the problem as soon as possible. This will allow you to repair the furnace before it causes significant damage to your home.
