Common Bryant Furnace Error Codes and Their Meanings

Bryant furnaces utilize LED lights to indicate specific error codes when there is a malfunction. Understanding these error codes can help in troubleshooting and resolving issues with your furnace. Here are some common Bryant furnace LED error codes and their meanings:

Code 13 (One long, three short flashes)

This error code indicates a dirty or incorrectly rated air filter. A dirty air filter can restrict airflow, leading to decreased performance and potential issues with the furnace. It is recommended to check and clean or replace the air filter regularly to avoid this error code.

Code 31 (Three short, one long flashes)

Code 31 relates to a pressure switch fault, typically caused by venting issues. A malfunctioning pressure switch can disrupt the proper circulation of air in the furnace, resulting in system shutdown. It is advisable to check the venting system for any obstructions or blockages and ensure proper airflow.

Code 33 (Three short, three long flashes)

When code 33 is displayed, it signifies a limit circuit fault. This fault can occur due to an open limit switch or flame rollout switch. These switches are safety devices designed to detect potential hazards, such as overheating. If this error code appears, it is essential to have a professional technician inspect and repair the furnace.

Code 43 (Four short, three long flashes)

Code 43 indicates a low-heat pressure switch open while the high-heat pressure switch is closed. This error code typically points to a problem with the pressure switches that regulate the flow of gas in different heat modes. Consulting a certified technician is recommended to diagnose and resolve this issue.

It is worth noting that these error codes are a general guideline, and their meanings may vary depending on the specific model and configuration of your Bryant furnace. When encountering any error codes, it is advisable to consult the furnace’s troubleshooting guide or seek professional assistance from an HVAC technician to ensure accurate diagnosis and efficient resolution.

Troubleshooting Steps for Bryant Furnace LED Codes

If you are experiencing LED codes on your Bryant furnace, there are a few troubleshooting steps you can take before contacting a professional technician. Follow these guidelines to potentially resolve the issue:

1. Check the air filter: Ensure that the air filter is clean and properly rated for your Bryant furnace. A dirty or incorrectly rated filter can cause the LED code.
2. Reset the power: Turn off the power to your furnace for at least 30 seconds, and then turn it back on. This power reset may clear the LED error code.
3. Check for obstructions: Ensure that the venting system for your furnace is clear of any obstructions or blockages. Blocked vents can trigger LED codes and impact the furnace’s performance.
4. Verify gas supply: Confirm that the gas supply to your furnace is not interrupted and that the gas valve is fully open. Insufficient gas supply can lead to LED error codes and heating issues.
5. Inspect the pressure switch: Check for any loose connections or obstructions at the pressure switch. Faulty pressure switches can trigger LED codes and disrupt the furnace’s proper operation.

If these troubleshooting steps do not resolve the issue with your Bryant furnace, it is recommended to contact a professional technician who specializes in Bryant furnace troubleshooting and repairs. They will have the expertise to diagnose the problem accurately and provide appropriate solutions to get your furnace back up and running efficiently.
