If you’re experiencing the dreaded Bryant furnace error code 13, don’t worry, we’re here to help. This error code indicates a limit circuit lockout, which means that the high limit or flame rollout switch has been open for more than 3 minutes. There could be several reasons for this error code, including a high limit fault, rollout fault, or even a restriction in air flow. In some cases, a simple troubleshooting step can resolve the issue and get your furnace running smoothly again. Let’s dive into the steps you can take to fix Bryant furnace error code 13.
Key Takeaways:
- Bryant furnace error code 13 indicates a limit circuit lockout.
- Possible causes of the error code include high limit or rollout faults and air flow restrictions.
- You can try troubleshooting steps, such as checking switch operation issues and ensuring proper air flow, to fix the error.
- Upgrading to a higher MERV-rated filter can sometimes lead to the error code 13 due to restricted air flow.
- If you’re unable to fix the error on your own, it’s advisable to seek professional assistance.
Troubleshooting Steps
If you’re facing the pesky Bryant furnace error code 13, you might be able to resolve it yourself by following a few troubleshooting steps. These steps can help identify and fix the issue without the need to call a professional. Follow these instructions to troubleshoot and potentially resolve Bryant furnace error code 13.
-
Check the switch operation: Ensure that the high limit switch is closed and the flame rollout switch is not tripped. If you notice any issues with these switches, they may need to be replaced.
-
Inspect the air flow: Make sure there are no air flow issues that may be causing the error code. Clean or replace the air filter if it’s dirty, open all vents and return registers, and ensure that the blower wheel and motor are clean and functioning properly.
-
Verify combustion air and intake pipes: Check for proper combustion air supply and ensure there are no blockages in the intake pipes. Clear any obstructions that may be hindering the air flow.
-
Adjust blower motor speed: If none of the previous steps resolve the error code, try increasing the speed of the blower motor during heat mode.
Following these troubleshooting steps should help you address the Bryant furnace error code 13 in many cases. However, if you’re unable to resolve the issue on your own, don’t hesitate to seek assistance from a professional HVAC technician for further diagnosis and repair.
The Impact of Upgraded Filters
It’s worth noting that upgrading to a higher MERV-rated filter can sometimes lead to Bryant furnace error code 13. The higher MERV rating can restrict the air flow over the furnace’s heat exchanger, causing it to go off on high limit. This can trigger an error 33, which may then lead to the error 13 due to safety lockout. If you’ve recently upgraded your filter and started experiencing error code 13, it’s possible that the restricted air flow is the culprit. In this case, you may need to revert to a lower-rated filter or find other ways to improve air flow around the furnace.
| Pros of Upgraded Filters | Cons of Upgraded Filters |
|---|---|
| Achieve higher indoor air quality by removing more allergens and contaminants. | Increased MERV rating can restrict air flow and potentially lead to Bryant furnace error code 13. |
| Reduce the frequency of filter replacement due to higher particle capture efficiency. | May require more frequent filter maintenance, including more frequent cleaning or replacement. |
| Enhance the overall performance of your HVAC system by preventing dust buildup and improving energy efficiency. | Higher-priced filters can be more expensive to purchase and maintain. |
