- Electrical Problems: Inspect wiring connections for corrosion or damage. Repair any issues you find.
Troubleshooting Steps
- Turn Off Power: Always start by turning off the power to the furnace for safety.
- Inspect Vents: Examine both intake and exhaust vents for blockages. Ensure they’re clear and unobstructed.
- Test the Pressure Switch: Use a multimeter to check the pressure switch. If it’s not functioning, replace it.
- Clear the Drain Line: Flush the condensate line with water to remove any blockages. Ensure proper drainage.
- Check Wiring: Tighten or replace any damaged wires. Make sure all electrical connections are secure.
When to Call a Professional
If troubleshooting doesn’t resolve the issue, it’s time to consult a professional. They can perform in-depth diagnostics and repairs, ensuring your furnace operates safely and effectively. Regular maintenance can prevent future problems, keeping your home warm and comfortable.
Common Causes of 6 Blinks
When your Goodman furnace flashes six blinks, it signals specific issues that require attention. Understanding these causes can streamline troubleshooting efforts.
Faulty Ignition System
A faulty ignition system often triggers the six-blink code. You might notice this if the burners don’t ignite or the pilot light is out. Check the following:
- Ignitor Function: Inspect the ignitor for damage or wear. If it’s cracked or coated with debris, replace it.
- Gas Supply: Ensure the gas valve is open and there is adequate gas pressure. A lack of gas can prevent ignition.
- Wiring Connections: Examine the wiring for loose or damaged connections. Secure any loose wires and replace worn-out ones.
Issues with the Flame Sensor
Issues with the flame sensor can also lead to the six-blink warning. If the sensor is dirty or malfunctioning, the furnace may shut down to prevent unsafe conditions. To troubleshoot:
- Cleaning the Sensor: Turn off the power and gently clean the flame sensor with fine sandpaper or a cloth. This removes soot or buildup that can inhibit performance.
- Testing the Sensor: Use a multimeter to check the sensor’s resistance. If it’s out of range, consider replacing it.
- Connection Integrity: Check the connections to the flame sensor for any sign of corrosion or damage. Tighten loose connections and replace any corroded components.
Keeping these common issues in mind can help you quickly identify and address the problem. Regular maintenance can also prevent these issues from recurring, ensuring your Goodman furnace operates efficiently throughout the winter.
Step-by-Step Troubleshooting Guide
You can follow these steps to troubleshoot a Goodman furnace showing six blinks. This guide helps identify and resolve common issues effectively.
Checking the Power Supply
- Turn Off the Furnace: Stop the unit and switch off the power at the breaker.
- Examine the Circuit Breaker: Ensure the breaker isn’t tripped. If it is, reset it by flipping it off and back on.
- Inspect the Disconnect Switch: Look for any disconnect switches near your furnace. Make sure they’re in the “on” position.
- Test Outlet Power: Use a multimeter to check if the outlet has power. If no power is detected, consider contacting an electrician.
Inspecting the Thermostat
- Access the Thermostat: Open the thermostat cover.
- Check Battery Levels: If your thermostat uses batteries, replace them if they’re low or dead.
- Verify Settings: Make sure it’s set to heat and the temperature setting is higher than the current room temperature.
- Inspect Wiring Connections: Tighten any loose connections within the thermostat.
- Open the Furnace Panel: Remove the access panel on your furnace, exposing the circuit board.
- Look for Faulty Connections: Check that all wires are securely attached. Look for any signs of burn marks or damage.
- Inspect for Blown Fuses: Locate any fuses on the circuit board. Replace blown fuses with ones of the same amperage.
- Check Error Codes: Refer to your furnace’s manual for specific error codes that may appear on the circuit board, indicating particular problems.
These steps guide you through the most common issues when your Goodman furnace displays six blinks. By following them, you can assess and possibly resolve the issue without further assistance.
Preventative Maintenance Tips
Regular maintenance ensures your Goodman furnace runs efficiently, reducing the risk of the six-blink error code. Follow these tips for effective upkeep:
Check the Air Filter Monthly
Replace or clean your air filter every month. A clogged filter restricts airflow, causing your furnace to work harder. This strain can lead to overheating and possible errors, including six blinks.
Inspect and Clean Vents and Ducts
Inspect your vents for blockages. Clear away obstructions like dust, dirt, or furniture. Schedule an annual professional duct cleaning. Clean ducts promote optimal airflow and efficiency.
Monitor Drain Lines
Examine your condensate drain lines regularly. Clear any clogs to prevent water buildup, which can cause pressure switch issues. Use a wet/dry vacuum to remove debris.
Test Carbon Monoxide Detector
Ensure your carbon monoxide detector works properly. Test it monthly and replace the batteries at least twice a year. This protects your home and alerts you to potential furnace problems.
Schedule Annual Professional Maintenance
Book an annual inspection with a qualified technician. Professionals check all furnace components, ensuring they function correctly. Routine maintenance can prevent the occurrence of the six-blink code.
Keep the Area Around the Furnace Clear
Maintain a clear space around your furnace. Store items at least two feet away from the unit. This prevents overheating and allows for proper airflow.
Listen for Unusual Noises
Pay attention to unusual noises while the furnace operates. Sounds like rattles, banging, or hissing may indicate underlying issues. Record these occurrences and mention them during your next service call.
Monitor Thermostat Settings
Check your thermostat settings regularly. Ensure it’s set to your desired temperature and functions accurately. A faulty thermostat can lead to improper furnace operation.
By following these preventative maintenance tips, you enhance the efficiency of your Goodman furnace and help prevent future issues, including the six-blink code. Taking proactive measures improves reliability and maintains a comfortable home during colder months.
