Code Definitions and Solutions
Open Limit Switch (Code 1)
An open limit switch often points to faulty thermostats or wiring issues. Check thermostat settings and inspect wiring connections for damage.
Pressure Switch Fault (Code 2)
A pressure switch fault indicates possible vent blockage or a damaged switch. Inspect the venting system for obstructions.
High Limit Switch Open (Code 3)
A high limit switch open error signifies overheating issues. Ensure air filters are clean and that vents are unobstructed.
Rollout Switch Tripped (Code 4)
If the rollout switch trips, it could suggest flame rollout or improper venting. Check combustible materials around the furnace and ensure proper venting is in place.
Ignition Failure (Code 5)
An ignition failure may occur due to a faulty ignitor or gas supply problem. Inspect the ignitor for damage, and confirm that gas is flowing to the furnace.
Flame Sensing Issue (Code 6)
A flame sensing issue can stem from a dirty flame sensor or faulty wiring. Clean the flame sensor gently and check wiring for integrity.
- Read the Manual: Always refer to your furnace’s manual for specific troubleshooting codes and guidance.
- Turn Off Power: Before performing any checks, turn off power to the furnace to ensure safety.
- Keep Records: Document error codes and any troubleshooting steps you take. This information helps when consulting a technician.

- Seek Professional Help: If you can’t resolve the problem after following troubleshooting steps, contact a qualified technician.
Common Troubleshooting Codes
Understanding the common troubleshooting codes for American Standard furnaces can help you identify issues quickly. Here are several error codes you might encounter, along with their meanings and suggested solutions.
Ignition Failure Codes
Ignition failure codes typically signal problems with the furnace’s ignition system. Common codes include:
- Code 3: Indicates a failure to ignite. Check the power supply and ensure gas is reaching the burner.
- Code 4: Signals an ignition lockout. Reset the furnace by turning it off at the thermostat for 30 seconds. If the issue persists, inspect the ignition components.
Flame Sensor Issues
Flame sensor issues can prevent your furnace from operating properly. Recognizable codes include:
- Code 7: Suggests a flame sensor fault. Clean the flame sensor with fine sandpaper to remove any buildup.
- Code 8: Indicates the flame sensor is not detecting flames. Inspect wiring for damage, and ensure the sensor’s position correctly aligns with the burner.
Pressure Switch Failures
Pressure switch failures can interrupt air flow and require immediate attention. Look for these codes:
- Code 14: Denotes a pressure switch failure due to blocked venting. Check the vent pipe for obstructions and ensure it’s clear.
- Code 16: Indicates a stuck pressure switch. Verify that connections are secure and replace the switch if necessary.
Familiarizing yourself with these codes helps you troubleshoot effectively and maintain your American Standard furnace efficiently. Always consult your furnace manual for specific codes and instructions.
Diagnostics Steps for Each Code
Understanding how to troubleshoot American Standard furnace codes directly impacts your ability to maintain a comfortable home. Follow the steps outlined for each diagnostic code to efficiently identify and rectify issues.
Step-by-Step Troubleshooting
- Identify the Code: Observe the flashing lights on the control board to determine the error code. Refer to the furnace manual for specific code meanings.
- Turn Off Power: Before performing any checks, turn off the furnace power at the circuit breaker. This ensures safety during your troubleshooting process.
- Check Filters: Inspect and clean or replace the air filter if it’s clogged. A dirty filter can restrict airflow and cause overheating, leading to fault codes.
- Inspect the Flame Sensor: Remove and clean the flame sensor with fine-grit sandpaper. A dirty or malfunctioning sensor can trigger ignition failure codes.
- Examine the Pressure Switch: Check the pressure switch hose for clogs or disconnections. Ensure the switch operates correctly by testing with a multimeter.
- Look for Obstructions: Examine the venting system for blockages. Clear any impediments that may restrict proper air or exhaust flow.
- Reset the System: If you resolve the underlying issue, reset the furnace by turning power back on. Watch for any new error codes after the reset.
- Multimeter: Essential for measuring voltage and resistance in electrical components.
- Screwdrivers: Helpful for removing panels and electrical connections.
- Ladder: Needed for accessing high vent pipes or ceiling-mounted units.
- Flashlight: Useful for inspecting dark areas within the furnace or ductwork.
- Soft Brush or Cloth: Effective for cleaning components like the flame sensor and burners.
- Safety Goggles and Gloves: Ensure personal safety while performing inspections and repairs.
By following these diagnostics steps and using the right tools, you can troubleshoot various American Standard furnace codes effectively.
