Understanding Bryant Furnace Error Code 33
Error code 33 on a Bryant furnace indicates an issue with the ignition process. This error often prevents the furnace from igniting, leaving you without heat.
What Does Error Code 33 Indicate?
Error code 33 signifies a problem with the pressure switch or the ignition system. The pressure switch monitors gas flow and system pressure. If it detects an issue, the furnace fails to ignite, displaying this error. You might experience this code after a power outage or if the furnace hasn’t been serviced in a while.
Common Symptoms of Error Code 33
Common symptoms accompanying error code 33 include:
- No Heat: The furnace fails to produce warmth, leading to a chilly home.
- Continuous Blowing: The blower motor may run continuously, trying to circulate air without effective heating.
- Flashing Indicator Lights: The status lights on the furnace may flash or blink, indicating a malfunction.
- Locked-Out System: Repeated attempts to ignite can cause the system to lock out, stopping operation altogether.
By recognizing these symptoms, you can take appropriate steps to address the issue.
Causes of Bryant Furnace Error Code 33
Error code 33 in your Bryant furnace often arises from specific issues within the system. Understanding these causes helps you troubleshoot effectively.
Faulty Limit Switch
A faulty limit switch represents a common trigger for error code 33. This component monitors the furnace’s temperature, shutting it down if it overheats. If the limit switch malfunctions, the furnace might not ignite. Regularly inspecting this switch ensures it functions correctly. You can easily check if it’s working by looking for any signs of excessive heat or other failures. Replacing a faulty limit switch can restore normal operation.
Blocked Venting
Blocked venting can also prompt error code 33. The venting system transports fumes outside, and any obstructions can create pressure issues. Debris, snow, or even bird nests often cause blockages. Inspect the vent pipes for any visible obstructions, and clear them carefully. Ensuring proper airflow prevents ignition problems and maintains safety. Regular maintenance of the venting system reduces the chances of encountering this issue in the future.
Troubleshooting Steps for Error Code 33
Error code 33 indicates issues with the ignition process. Taking the right steps can help you resolve it quickly.
Initial Checks to Perform
- Ensure Power Supply: Confirm that the furnace receives adequate power. Check circuit breakers and replace blown fuses if necessary.
- Inspect Thermostat Settings: Verify that the thermostat is set correctly. It should be on “heat” and above room temperature.
- Examine Air Filter: Check and replace a dirty air filter, which can restrict airflow and impact system performance.
- Clear Venting: Inspect the venting system for blockages. Remove any debris or obstructions that can affect air pressure.
- Locate the Limit Switch: Find the limit switch, typically near the heat exchanger or plenum.
- Use a Multimeter: Set your multimeter to the continuity setting. Disconnect power to your furnace for safety.
- Test for Continuity: Connect the multimeter probes to the terminals of the limit switch. A reading indicates the switch is functioning; no reading means replacement is necessary.
- Check Reset Function: If your limit switch includes a reset button, test it. Press the button and monitor if the furnace attempts to ignite.
Following these troubleshooting steps can help identify and fix the cause of error code 33 effectively. If the issue persists, consider contacting a professional for further assistance.
When to Call a Professional
Recognizing when to engage a professional is crucial for effectively dealing with Bryant furnace error code 33. If troubleshooting steps don’t resolve the issue, professional assistance becomes necessary.
Signs You Need Expert Help
