What Is the Goodman Furnace Reset Button?

The Goodman furnace reset button is a manual control designed to reset the furnace’s electronic control board or safety limit switches after they trigger a safety shutdown. Many Goodman furnace models are equipped with this button to protect the unit and home occupants from unsafe conditions such as overheating or flame rollout. By pressing this button, homeowners can attempt a safe restart of the system. However, it is not meant as a permanent fix but rather a troubleshooting tool.

Where to Find the Reset Button on a Goodman Furnace

The location of the reset button varies by model but is commonly found within the blower compartment or near the furnace’s control panel. Typically, it is a red or black push button, sometimes labeled “RESET” or “Limit Reset.” To access it, users often need to remove the furnace access panel carefully.

Steps to Locate the Reset Button:

• Turn off power to the furnace
• Remove the front access panel using a screwdriver if necessary
• Look for a small red or black button near the blower motor or control board
• Consult the user manual for model-specific guidance

Always ensure power is off before attempting to locate or press the reset button to avoid electrical hazards.

When and Why to Use the Goodman Furnace Reset Button

The reset button should be used only when the furnace has shut down due to tripped safety features. Common scenarios include:

• Overheating: The limit switch or high-temperature limit sensor triggers a shutdown to prevent damage.
• Flame Failure: If the furnace detects no flame when the gas valve is open, it may shut off to prevent gas leaks.
• Power Interruptions or Faults: Temporary electrical faults may cause the furnace to stop operating.

Using the reset button immediately after the furnace shuts down can sometimes restore normal operation, but persistent issues require professional attention. Resetting without diagnosing can pose risks.

Proper Procedure to Reset a Goodman Furnace

1. Turn Off Power: Switch off the furnace at the thermostat and main electrical panel to ensure safety.
2. Locate the Reset Button: Follow the steps outlined above to find the button on your model.
3. Press and Hold: Press the reset button firmly for 5 to 10 seconds and then release it.
4. Restore Power: Turn the furnace power back on at the breaker and thermostat.
5. Observe Operation: Allow the furnace to start and stabilize. Listen for unusual noises or observe error codes if your unit has a digital display.

Do not press the reset button repeatedly without allowing the system to cool down first, as this can cause damage.

Troubleshooting Common Issues Related to the Reset Button

If pressing the reset button does not restore furnace operation, consider the following troubleshooting steps:

• Check Thermostat Settings: Ensure it is set to “Heat” mode and temperature is above room temperature.
• Inspect Air Filters: Dirty or clogged filters can cause overheating and frequent shutdowns.
• Examine Vents and Registers: Blocked airflow can trigger safety limits to trip.
• Look for Error Codes: Many Goodman furnaces have diagnostic lights or codes indicating specific faults.
• Verify Power Supply: Make sure the furnace is receiving adequate electrical power.
• Assess Flame Sensor and Ignition: Faulty sensors can cause flame failure and shutdowns.

If these checks do not resolve the issue, scheduling professional furnace service is advisable.

Safety Considerations When Using the Reset Button

While the reset button offers a quick way to restart a furnace, it is vital to never ignore the underlying cause of shutdowns. Repeated use of the reset button without addressing mechanical or electrical problems may lead to:

• Risk of fire or gas leaks
• Damage to furnace components
• Increased energy costs
• Potential voiding of warranty coverage

Always follow manufacturer instructions and safety guidelines. If unsure, consult a licensed HVAC professional.

When to Call a Professional for Goodman Furnace Reset Issues

Contact an HVAC technician if:

• The furnace requires multiple resets within a short period
• The furnace fails to restart after pressing the reset button
• You notice abnormal smells, noises, or visible damage
• The reset button is damaged or stuck
• There are concerns about gas leaks or carbon monoxide

Professional technicians can diagnose complex problems, perform necessary repairs, and ensure your furnace operates safely and efficiently.

Maintaining Your Goodman Furnace for Reliable Operation

Regular maintenance reduces the likelihood of safety shutdowns and the need to use the reset button. Recommended maintenance tasks include:

• Changing furnace air filters every 1-3 months
• Cleaning burners and flame sensors annually
• Inspecting and cleaning blower fans
• Checking and sealing ductwork leaks
• Annual professional inspection and tune-up

Proactive upkeep extends furnace lifespan and enhances heating performance.
