What Is The Gibson Furnace Reset Button?
The Gibson furnace reset button is part of a safety mechanism that stops the furnace when a fault occurs, such as overheating, a flame sensor issue, or a restricted vent. Pressing and releasing the button resets the control board after the fault condition has been cleared. It is not a substitute for addressing underlying problems, and repeated resets may indicate an ongoing issue that needs professional evaluation. The reset button is typically located on or near the burner assembly or control board and is often colored red or a contrasting shade for visibility.
Commonly, the reset button serves as a temporary remedy to restore operation after the fault has been addressed. Homeowners should follow safety steps, avoid forcing resets, and use the reset as a diagnostic tool rather than a permanent fix. If the furnace continues to trip after a reset, the underlying cause must be identified and resolved to prevent safety hazards and potential damage to the furnace system.
Where Is The Reset Button On Gibson Furnaces?
Locations for the Gibson furnace reset button can vary by model and installation. In many Gibson gas furnaces, the reset button is inside the access panel of the burner compartment, near the ignition module or the flame sensor. Some models place the button on the primary control board or gas valve area behind the lower service panel. Access typically requires switching off power and removing the panel to view internal components. Always follow manufacturer instructions and shut off power at the disconnect switch before opening the furnace.
If the button is not obvious, consult the unit’s manual or label on the inside of the cabinet for exact location guidance. For older or compact Gibson models, the reset button may be mounted on the gas valve or near the burner assembly. In any case, avoid forcing components or pressing other buttons that you don’t recognize. When in doubt, contact a licensed HVAC technician to locate and operate the reset safely.
| Model Type | Typical Reset Button Location |
|---|---|
| Older Gibson Gas Furnaces | Inside blower/compressor area, behind access panel |
| Newer Gibson Gas Furnaces | Near the ignition module or control board, behind service panel |
| Compact/Hybrid Gibson Units | Gas valve area or burner assembly |
Safety Precautions Before Resetting
- Turn off power to the furnace at the dedicated switch or the main breaker to prevent electric shock.
- Shut off the gas supply if you smell gas or suspect a gas leak, and evacuate the area if necessary.
- Ensure the furnace has cooled after overheating before attempting a reset to avoid burns or fire risk.
- Do not reset the system repeatedly in quick succession. If the problem persists, seek professional help.
- Keep children and pets away from the furnace while performing any reset or inspection.
Common Reasons To Reset A Gibson Furnace
Resetting is commonly required after safety devices trip due to overheating, flame sensor issues, or a temporary fault in ignition. Other causes include a dirty air filter restricting airflow, a blocked vent or chimney, a pressure switch fault, or a temporary electrical glitch on the control board. A reset may clear minor faults, but persistent issues indicate a deeper problem that needs diagnostics by a technician. Recurrent resets can also mask a failing heat exchanger or gas valve problem, which requires professional assessment.
Before performing a reset, consider whether any obvious maintenance tasks are due, such as filter replacement or duct cleaning. Addressing these non-electrical concerns can reduce the likelihood of future resets and improve furnace efficiency and safety. If resets become more frequent or the furnace fails to stay on after a reset, prioritize a service call to prevent further damage or safety hazards.
Step-By-Step Guide To Resetting A Gibson Furnace
Preparation
Begin by turning off power at the furnace switch or the main electrical panel. If you can access the gas valve safely, ensure the gas supply is steady and there are no gas leaks. Wait several minutes for any residual heat to dissipate and for the system to reach ambient conditions. If you smell gas, do not attempt a reset; leave the area and contact emergency services or your gas provider. Retrieve the manual if possible to locate the exact reset button position and any model-specific steps.
Reset Procedure
With safety checks complete, turn the power back on or switch the furnace to standby. If the reset button is clearly accessible, press and hold it for 3 to 5 seconds, then release. Some models require you to hold for a longer period up to 10 seconds; follow the specific model instructions if available. After releasing, wait about 60 seconds for the system to attempt ignition. Set the thermostat to heat and the desired temperature. Observe the ignition sequence and listen for the burner flame. If ignition occurs, allow the furnace to run for several minutes to stabilize, then recheck airflow and room temperature. If the furnace does not ignite or immediately trips again, do not repeatedly press the reset button. Proceed to troubleshooting or contact a technician.
If the system enters a fault code while restarting, consult the manual for the meaning of the LED indicators or error codes on the control board. Many Gibson furnaces display a sequence of blinks or a combination of LED colors to indicate specific faults, such as flame sensor problems or ignition failure. Only proceed with further troubleshooting if you are confident in your abilities and safety, otherwise schedule professional service to avoid potential hazards.
Troubleshooting After Reset
If the furnace stays on after a reset, monitor for any recurring trips or irregular operation. If the system fails to ignite again, proceed with targeted troubleshooting: check the flame sensor for cleanliness; dirty sensors can prevent ignition and trigger a trip. Inspect the air filter and replace if dirty to improve airflow and prevent overheating. Verify the venting path for blockages or restrictions that could cause backdrafting or furnace shutdown. Confirm the gas supply is steady and the gas valve is fully open. Inspect electrical connections and ensure there are no loose wires on the control board or limit switch.
Document any error codes shown by the furnace’s LED indicator. A repair technician can interpret codes to determine whether the issue lies with the flame sensor, ignition system, gas valve, pressure switch, or control board. If there is any sign of burning odors, smoke, or gas smell, leave the area immediately and call emergency services. Do not operate a furnace that shows signs of a fuel leak or significant malfunction.
Maintenance Tips To Prevent Future Resets
- Replace or clean the air filter every 1–3 months, depending on usage and household conditions. A clogged filter reduces airflow and can trigger overheating.
- Schedule annual preventative maintenance with a licensed HVAC technician to inspect the heat exchanger, ignition system, blower motor, and safety controls.
- Keep the area around the furnace clear of dust, debris, and clutter to maintain proper ventilation and airflow.
- Test and replace carbon monoxide detectors in the home, ensuring early warning of dangerous conditions.
- Verify that the venting system is unobstructed and free from bird nests, snow buildup, or debris that could impede exhaust.
- Inspect and test the thermostat and wiring for proper operation and calibration to avoid false heat calls.
When To Call A Professional
Call a licensed HVAC technician if the Gibson furnace continues to trip after resets, ignites briefly but shuts down, or shows persistent error codes. Seek immediate help if there is a gas smell, unusual noises, or soot around the furnace, as these can indicate leaks or a faulty heat exchanger. Regular maintenance by a professional can diagnose issues before they cause repeated resets and extend the life of the furnace. Do not attempt advanced repairs beyond basic reset and safety checks without appropriate training.
