Troubleshooting Common Errors
While the Bryant Plus 90 furnace is designed for reliability, issues can arise. Understanding common errors and how to troubleshoot them can help you resolve problems quickly and safely. Here’s a guide to troubleshooting some common errors⁚
Error Code 33⁚
Error code 33 typically indicates a high limit fault. This could be due to a faulty roll-out switch, a problem with the high limit switch inside the heat exchanger blower compartment, or an issue with the heat exchanger itself. A qualified technician should diagnose and address the problem.
Error Code 34⁚
Error code 34 usually signals a problem with the ignition process. This could be caused by a faulty igniter, a blocked gas valve, or a problem with the control board. A technician should investigate and resolve the issue.
Furnace Not Running⁚
If the furnace is not running at all, start by checking the thermostat to ensure it’s set to “Heat” and that the temperature setting is below the current room temperature. Then, check the circuit breaker to ensure it’s not tripped. If the furnace still doesn’t run, a technician should diagnose the problem.
Furnace Running But Not Heating⁚
If the furnace is running but not providing heat, check the air filter. A dirty air filter can restrict airflow and prevent heat from being distributed. Also, inspect the venting system for blockages. If the problem persists, professional assistance is recommended.
