Troubleshooting Tips for Bryant Error Code 13
When faced with Bryant error code 13, it is crucial to address the issue promptly to restore the proper functioning of your unit. Error code 13, also known as Limit Circuit Lockout, indicates that the high limit or flame rollout switch has been open for more than 3 minutes. This can be caused by insufficient airflow, triggering a safety lockout mechanism.
To troubleshoot Bryant error code 13, consider the following steps:
- Check the high limit switch for proper operation and continuity. If the switch is open, it may need to be replaced.
- Inspect the flame rollout switch for any back drafts or blocked flues that might be causing the error. Resetting the flame rollout switch can also help resolve the issue.
- Ensure that the air filters are clean and not obstructing the airflow. It is essential to open all vents and return registers to maintain adequate airflow throughout the system.
- Examine the condition of the blower wheel and motor. Make sure there is proper combustion air for efficient functioning.
- Consider increasing the speed of the blower motor during the heat mode to improve airflow and troubleshoot the error.

Common Causes of Bryant Error Code 13
When encountering Bryant error code 13, it is important to identify the underlying causes to effectively troubleshoot and resolve the issue. Understanding the common reasons behind this error can help you address the problem and prevent future occurrences.
One possible cause of Bryant error code 13 is a restricted airflow over the furnace’s heat exchanger due to a higher MERV-rated filter. This can lead to the furnace going off on high limit, triggering error 33, which subsequently results in error 13.
Additionally, back drafts, blocked flues, and dirty A/C evaporator coils can contribute to the occurrence of Bryant error code 13. These issues can disrupt the proper airflow within the system, leading to the activation of the error message.
Problems with the blower wheel, blower motor, and combustion air can also cause air flow complications and trigger error code 13 on Bryant systems. Addressing these issues is crucial to restore proper air circulation and resolve the error.
Example Table: Common Causes of Bryant Error Code 13
| Causes | Description |
|---|---|
| Restricted Airflow | A higher MERV-rated filter restricts airflow over the furnace’s heat exchanger, leading to error code 13. |
| Back Drafts and Blocked Flues | Back drafts and blocked flues can disrupt the proper airflow, triggering the error message. |
| Dirty A/C Evaporator Coils | Dirty A/C evaporator coils can contribute to restricted airflow, resulting in error code 13. |
| Issues with Blower Wheel and Motor | Problems with the blower wheel and motor can cause air flow complications, leading to the activation of error code 13. |
| Combustion Air Problems | Inadequate combustion air can disrupt proper air circulation and trigger the error message. |
By addressing these common causes, you can effectively troubleshoot and resolve Bryant error code 13. Next, we will discuss the steps to take in Section 4 to fix this error and ensure your Bryant unit functions properly.
Conclusion
In conclusion, troubleshooting Bryant error code 13 requires addressing air flow issues and resolving underlying problems. By following the troubleshooting tips mentioned above, including checking the high limit switch and flame rollout switch, ensuring proper air flow, and inspecting the blower wheel and motor, you can fix the error and restore the functionality of your Bryant unit.
If you encounter difficulties in resolving the error on your own, it is recommended to seek professional assistance. Qualified technicians can diagnose the issue accurately and provide the necessary repairs to resolve Bryant error code 13.
To prevent future occurrences of error code 13, it is essential to perform regular maintenance on your Bryant system. This includes cleaning or replacing filters regularly, keeping vents and return registers open, and ensuring proper combustion air. By taking these preventive measures, you can minimize the chances of encountering error code 13 and ensure the smooth operation of your Bryant unit.
