When encountering Bryant error code 33, it’s important to take the necessary troubleshooting steps to identify and resolve the issue. Below, we have outlined common solutions that can help fix the error and restore the proper functioning of your Bryant HVAC system.

1. Check for open switches: Start by inspecting the limit and flame rollout switches. Ensure that they are not open or stuck in the open position. If any switches are open, they will need to be replaced to resolve the error.
2. Inspect connections and switches: Examine the connections and wires associated with the limit and rollout switches. Look for any loose or damaged connections. If any issues are found, secure or replace the connections as needed.
3. Adjust gas input settings: Improper gas input adjustment can also trigger error code 33. Verify that the gas input is correctly adjusted according to the manufacturer’s specifications. If necessary, adjust the gas input to the appropriate level.
4. Inspect the blower wheel: A loose blower wheel can cause the furnace to operate in high-heat only mode, resulting in error code 33. Carefully examine the blower wheel for any signs of looseness or misalignment. If any issues are detected, tighten or realign the blower wheel to ensure proper operation.
5. Check the gas valve: A stuck high-heat solenoid in the gas valve can also be a potential cause of error code 33. Inspect the gas valve and ensure that the solenoid is not stuck in the open position. If necessary, replace the gas valve or solenoid.

By following these troubleshooting steps, you can effectively address the common causes of Bryant error code 33 and resolve the issue. However, if you are unsure about any of the steps or if the error persists, it is recommended to seek professional assistance from a qualified HVAC technician.
