Understanding Goodman Furnace Ignitors
Goodman furnace ignitors play a crucial role in the heating process by lighting the gas that warms your home. Understanding different types of ignitors and common issues helps you troubleshoot effectively.
Types of Ignitors Used in Goodman Furnaces
Goodman furnaces typically use two main types of ignitors:
- Hot Surface Ignitors: These ignitors heat up electrically to ignite gas. Often made of silicon carbide, they glow orange when activated. These ignitors are standard in many Goodman models because of their reliability.
- Spark Ignitors: A spark ignitor generates a spark to ignite the gas. These are less common in modern Goodman models but may be found in older systems. They require a working ignition module that sends an electric charge.
Knowing the type of ignitor in your Goodman furnace helps simplify troubleshooting steps.
Common Ignitor Issues
Several issues can hinder the performance of your Goodman furnace ignitor:
- Electrical Problems: Loose or damaged wires can disrupt electrical flow. Check all connections for wear or corrosion.
- Burnt-Out Ignitor: Ignitors can wear out over time. If your furnace won’t ignite, inspect the ignitor for cracks or discoloration. Replace it if necessary.
- Clogged Gas Line: A clogged line can prevent the ignitor from receiving gas. Ensure gas supply is clear before troubleshooting the ignitor.
- Faulty Flame Sensor: A malfunctioning flame sensor may not register that the furnace has ignited. Clean or replace the sensor if you suspect it’s faulty.
Identifying these issues accelerates the troubleshooting process, helping you get your furnace back up and running swiftly.
Troubleshooting Goodman Furnace Ignitor
Troubleshooting a Goodman furnace ignitor involves several steps. By following a systematic approach, you’ll efficiently identify the issue.
Step-by-Step Troubleshooting Guide
- Check Power Supply: Ensure the furnace has power. Inspect the circuit breaker for any tripped switches. Reset any if necessary.
- Examine the Ignitor: Remove the ignitor and inspect it for any signs of damage or wear. Look for cracks or burnt areas.
- Test the Ignitor: Use a multimeter to test the ignitor’s resistance. A reading below 40 ohms usually indicates a faulty ignitor that needs replacement.
- Inspect Wiring Connections: Check all electrical connections to the ignitor. Confirm that wires are securely connected and not frayed or damaged.
- Clean Flame Sensor: A dirty flame sensor can prevent ignition. Gently clean it with fine sandpaper or a soft cloth.
- Check Gas Supply: Ensure that the gas valve is open and that there are no clogs in the gas line. If you suspect a blockage, contact a professional.
- Look for Error Codes: If your furnace has a diagnostic indicator, check for error codes that can provide insight into the problem.
| Tool | Purpose |
|---|---|
| Multimeter | To test electrical resistance of the ignitor |
| Screwdriver | To remove and install the ignitor |
| Sandpaper or Cloth | To clean the flame sensor |
| Flashlight | To inspect hard-to-see areas |
| Safety Goggles | To protect your eyes during troubleshooting |
Having the right tools simplifies the troubleshooting process. Complete these steps carefully, and you’ll restore your Goodman furnace to functionality.
Common Symptoms of Ignitor Problems
Furnace ignitor issues often manifest through specific symptoms. Recognizing these signs early helps prevent more significant problems in your Goodman furnace.
Ignitor Not Lighting
An ignitor that fails to light indicates a malfunction. When the thermostat calls for heat but you notice no response, it’s time for a check. Common causes include:
- Burnt-Out Ignitor: A burnt-out hot surface ignitor won’t heat up, preventing ignition. Inspect the ignitor for cracks or discoloration.
- Faulty Electrical Connection: Loose or damaged wires can disrupt power. Ensure all connections are secure and inspect the wiring for wear.
- Power Supply Issue: Check your home’s circuit breaker. If a tripped breaker caused a loss of power, resetting it may solve the problem.
Follow these steps: Turn off the furnace power, inspect the ignitor carefully, and replace it if necessary.
Error Codes Related to Ignitor Issues
Many Goodman furnaces display error codes that help identify specific problems. Look for flash patterns on the LED indicator light. Common codes related to ignitor issues include:
- Error Code 14: Indicates a failure to ignite after three attempts.
- Error Code 33: Signals a low flame signal, often due to a faulty ignitor or flame sensor.
Refer to your owner’s manual for precise error code meanings and troubleshooting steps. Taking action based on these codes can quickly address ignitor-related problems.
Replacing a Goodman Furnace Ignitor
Replacing a Goodman furnace ignitor involves recognizing when a replacement is necessary and following safe procedures during the process.
When to Replace the Ignitor
Replace the ignitor if it shows physical damage, such as cracks or breaks. Replace it if it’s not glowing bright orange or if it fails to produce a spark during ignition attempts. Also, consider replacement if error codes indicate ignitor issues, like Error Code 14, which signifies ignition failures.
- Turn Off Power: Switch off the power to the furnace at the breaker box. This step prevents electrical shocks during the replacement process.
- Disconnect Gas Supply: Shut off the gas supply to the furnace to ensure safety while working.
- Locate Ignitor: Open the furnace access panel and locate the ignitor. It’s usually near the burner assembly.
- Remove Old Ignitor: Carefully disconnect wires from the ignitor. Use a screwdriver to remove any screws securing it in place and gently pull it out.
- Install New Ignitor: Position the new ignitor in the same spot as the old one. Secure it with screws and reconnect the wires, ensuring proper connections for efficient operation.
- Reassemble Furnace: Replace the access panel securely, ensuring all components function correctly.
- Restore Gas and Power: Turn the gas supply back on and switch the power on at the breaker box.
- Test the Furnace: Set your thermostat and allow the furnace to cycle on. Observe the ignitor to ensure it glows and allows the furnace to light properly.
By following these steps, you restore your Goodman furnace’s heating capabilities safely and effectively.
