Did you know that a staggering number of Carrier furnaces experience error code 14, also known as ignition lockout? This common issue can leave homeowners shivering in the cold as their furnace shuts down, unable to provide adequate heat. If you’ve encountered code 14 on your Carrier furnace, don’t worry! We’re here to help you troubleshoot and resolve this problem so you can regain the comfort of a warm and cozy home.
When a Carrier furnace displays error code 14, it indicates an ignition lockout. This means that the furnace control board did not detect a flame or adequate flame and has shut down. Error code 14 is typically triggered after error code 34 occurs three times. The furnace will reset the error code after three hours, but it can also be manually reset by turning the furnace off for 60 seconds and then back on.
In order to fix error code 14, there are several potential causes to consider and troubleshooting steps to take. From checking for oxide buildup on the flame sensor to inspecting the burners for dirt and clogs, we’ll walk you through each step to get your Carrier furnace back up and running.
Key Takeaways:
- Carrier furnace code 14 is an ignition lockout error that can leave your home without heat.
- The error code can be reset manually or will reset automatically after three hours.
- Possible causes include oxide buildup on the flame sensor, a shut-off gas valve, low gas pressure, improper grounding, and dirty burners.
- You can resolve the issue by cleaning the flame sensor, checking the gas valve, adjusting gas pressure, ensuring proper grounding, and cleaning the burners.
- If you’re unsure about any of the troubleshooting steps, it’s best to consult a professional HVAC technician for assistance.
Causes of Carrier Error Code 14
When encountering Carrier furnace error code 14, it’s important to identify the underlying causes in order to implement effective troubleshooting solutions. By understanding the potential reasons for this error code, we can take the necessary steps to resolve the issue and restore the proper functioning of the furnace.
Oxide buildup on the flame sensor:
One common cause of error code 14 is the presence of oxide buildup on the flame sensor. Over time, the sensor may accumulate soot or oxidation, preventing it from detecting or maintaining a flame. To address this issue, remove the flame sensor and carefully clean it using plain steel wool. This will help eliminate any buildup and ensure proper functioning.
In some cases, a manually shut-off gas valve can trigger error code 14. It’s important to ensure that the gas shut-off valve on the gas line going to the furnace is turned on. Additionally, check that the on/off switch on the valve is in the correct position to allow the flow of gas to the furnace.
Low inlet gas pressure:
Insufficient gas pressure at the gas valve can also lead to error code 14. To address this, utilize a manometer to measure the gas pressure at the gas valve. Adjust the set screws as necessary to achieve the proper gas pressure, ensuring a consistent and reliable fuel supply to the furnace.
Improper grounding of controls or flame sensor:
Improper grounding can interfere with the functioning of the furnace, potentially triggering error code 14. Ensure that the ground wire is securely attached to the gas manifold and that the flame sensor is properly mounted. By establishing proper grounding connections, we can eliminate this as a potential cause of the error code.
Dirty or clogged burners:
Furnace burners that are dirty or clogged can also contribute to error code 14. It’s important to inspect the burners for any accumulation of soot or rust, as this can hinder proper ignition. Clean the burners using a wire brush or pipe cleaners to remove any debris and ensure optimal performance.
In summary, error code 14 on a Carrier furnace can be caused by various factors such as oxide buildup on the flame sensor, a manually shut-off gas valve, low gas pressure, improper grounding, or dirty burners. By identifying and addressing these potential causes, we can effectively resolve error code 14 and ensure the efficient operation of the furnace.
Troubleshooting Carrier Furnace Code 14
If you encounter Carrier furnace code 14, there are several troubleshooting steps you can take to resolve the issue.
- Start by checking for oxide buildup on the flame sensor and cleaning it thoroughly.
