Carrier Error Code 14: Ignition Lockout
How to Fix Carrier Code 14
- Step 1: Ensure that the manual gas shutoff valve located near the furnace is fully open. The handle should be parallel to the gas pipe.
- Step 2: Check the furnace filter and replace it if it's dirty. A clogged filter can restrict airflow and affect combustion.
- Step 3: Do not attempt to restart the furnace. Call a qualified HVAC technician to inspect the system and diagnose the problem.
What Does Carrier Error Code 14 Mean?
The Carrier error code 14, also known as an ignition lockout, means your furnace tried to ignite the burners multiple times but failed. After several unsuccessful attempts, the control board locks out the system as a safety precaution. This prevents the continuous flow of gas into the combustion chamber, which could create a dangerous situation. This lockout requires manual reset in some cases, but should only be done after the underlying problem is resolved. Several factors can cause this issue, ranging from a faulty gas valve to a blocked flue. Because this code indicates a potential safety hazard related to gas flow and combustion, it's important to have a qualified HVAC technician diagnose and repair the problem. Do not attempt to troubleshoot gas-related components yourself.
Common Causes of Carrier Code 14
