Goodman gas furnace troubleshooting can help identify and address common problems to ensure optimal performance and heating in your home.
Common Troubleshooting Tips
When your Goodman gas furnace experiences issues, it can be frustrating and uncomfortable, especially during cold winter months. However, before calling a professional technician, you can try these common troubleshooting tips to potentially resolve the problem:
Check Circuit Breaker Or Fuse Box
If your Goodman furnace isn’t turning on, the first step is to check your circuit breaker or fuse box. Sometimes, a tripped circuit or blown fuse can cause the furnace to stop functioning. Simply locate your circuit breaker panel or fuse box and check if any breakers have flipped or fuses have blown. If you find any, try resetting the circuit breaker or replacing the blown fuse.
In addition to checking the circuit breaker or fuse box, it’s also crucial to make sure the furnace power switch is turned on. Ensure it is securely in the “On” position. Sometimes, the switch can accidentally get turned off, causing the furnace to stop working.
Resetting The Furnace
If checking the circuit breaker or fuse box doesn’t solve the issue, you can try resetting the furnace itself. Locate the furnace’s front access panel and remove it to expose the internal components. Look for a small red reset button and press it. This will reset the furnace and may resolve minor issues that caused it to stop working.
After resetting the furnace, wait for a few minutes and check if it ignites. If it doesn’t, proceed to the next troubleshooting tip.
Cleaning The Sensor And Replacing The Ignitor
If the furnace still fails to ignite after resetting it, the problem might be with a faulty sensor or a dirty ignitor. Over time, these components can get dirty or damaged, preventing proper ignition.
To clean the sensor, start by turning off the furnace power and removing the sensor. Use a soft cloth or fine-grit sandpaper to gently clean the sensor’s surface. Removing any dirt or debris can improve its functionality.
Next, if cleaning the sensor doesn’t solve the issue, consider replacing the ignitor. The ignitor is responsible for initiating the gas burners, so a faulty ignitor can prevent the furnace from igniting. Refer to your furnace’s manual or contact a professional technician for guidance on finding and replacing the ignitor.
By following these common troubleshooting tips, you may be able to resolve minor issues with your Goodman gas furnace and restore its proper functioning. However, if the problem persists or you are unsure of what to do, it’s always best to seek the assistance of a trained professional.
Specific Goodman Furnace Issues
Experiencing specific issues with your Goodman gas furnace? If your furnace isn’t turning on, check your circuit breaker or reset the furnace with the front access panel. If your furnace initiates but doesn’t ignite, it may be a problem with the ignitor/sensor, which can be cleaned or replaced.
Noisy Furnace
If you’re experiencing a noisy Goodman furnace, it’s important to address the issue as soon as possible. A noisy furnace can be disruptive and indicate underlying problems. Here are a few possible causes and troubleshooting steps:
1. Loose components: Check if any components, such as the blower motor or ductwork, are loose. Tighten or secure them if necessary.
2. Damaged blower motor: A damaged blower motor can cause excessive noise. If you suspect this is the issue, you may need to replace the blower motor to resolve the problem.
3. Dirty filters: Dirty filters can restrict airflow and cause the furnace to work harder, resulting in increased noise. Replace the filters regularly to ensure proper airflow and reduce noise levels.
4. Lack of maintenance: Regular maintenance is essential to keep your furnace running smoothly and quietly. Schedule annual professional maintenance or perform basic maintenance tasks, such as cleaning the blower assembly and lubricating moving parts.
Furnace Not Heating

1. Thermostat settings: Double-check the thermostat settings to ensure they are properly configured for heating mode. Sometimes, a simple adjustment is all it takes to resolve the issue.
2. Ignition problems: If the furnace is not igniting, the ignitor/sensor may be faulty, dirty, or damaged. Clean or replace the ignitor/sensor to restore proper ignition.
3. Pilot light: If your Goodman furnace has a pilot light, make sure it is lit. If it’s not, follow the manufacturer’s instructions to relight the pilot light safely.
4. Gas supply: Check if the gas supply to the furnace is uninterrupted. If there are issues with the gas supply, contact a professional to address the problem.
Furnace Stopping And Starting
A Goodman furnace that keeps stopping and starting can disrupt your comfort and may indicate an issue. Here are a few possible causes and troubleshooting steps to address this problem:
1. Thermostat issues: Check the thermostat to ensure it is functioning properly. Faulty wiring, loose connections, or incorrect settings can cause the furnace to stop and start irregularly.
2. Restricted airflow: A restricted airflow due to dirty filters or blocked vents can cause the furnace to overheat, triggering safety features that shut it off. Clean or replace the filters and ensure proper ventilation to prevent overheating.
3. Blower motor problems: A malfunctioning blower motor can cause the furnace to cycle on and off. Inspect the blower motor for any damage or issues and consider professional repair or replacement if needed.
4. Ignition issues: Faulty ignition components can lead to frequent cycling. Clean or replace the ignitor/sensor to ensure proper and consistent ignition.
Furnace Won’t Stop Running
If your Goodman furnace won’t stop running, it can result in unnecessary energy consumption and potential damage to the system. Here are a few potential causes and troubleshooting steps to resolve the issue:
1. Thermostat settings: Check the thermostat settings to ensure they are not accidentally set to continuous fan mode. Adjust the settings to the desired heating or cooling mode.
2. Malfunctioning limit switch: The limit switch is a safety feature that ensures the furnace does not overheat. If the limit switch is faulty, it may cause the furnace to continually run. Consult a professional to replace the limit switch if necessary.
3. Blocked airflow: Inspect the air filters, vents, and ductwork for any blockages. Restricted airflow can cause the furnace to work harder, leading to continuous operation. Clear any obstructions to restore proper airflow.
4. Faulty thermostat: If the thermostat is not accurately reading the temperature, it may cause the furnace to run continuously. Calibrate or replace the thermostat to rectify the issue.
Remember, if you encounter any issues with your Goodman gas furnace that you are unable to resolve, it’s always best to consult a professional HVAC technician for proper diagnosis and repair.
