What Is The Gibson Furnace Reset Button?

The Gibson furnace reset button is a manual safety or control switch designed to clear certain fault conditions and restart the furnace control system. It may be labeled “reset,” “restart,” or integrated into the furnace’s control module. It is not a substitute for diagnosis and should be used only for transient faults.

Where To Find The Gibson Furnace Reset Button

Gibson furnaces, including models sold under Gibson, White-Westinghouse, or Kelvinator, place the reset control in a few typical locations. Checking the right area prevents unnecessary disassembly and ensures safe operation.

Common Locations

• On the Furnace Control Panel: A red or black button on the electrical control box behind the front panel.
• Behind the Blower Access Door: Near the motor or on the switch housing where the blower connects.
• Near The Pilot Or Burner Assembly: On older models with a manual reset for thermocouple circuits.
• On The Gas Valve Assembly: Some designs include a reset on or close to the gas valve or pressure switch housing.

How To Use The Gibson Furnace Reset Button Safely

Use the reset button only when it is safe to do so. The reset clears certain lockouts but repeated pressing can mask persistent faults and create unsafe conditions.

Step-By-Step Reset Procedure

1. Turn Off Power: Switch off the furnace power at the service switch or breaker to prevent electrical arcs.
2. Wait A Minimum Of 5 Minutes: Allow controls, capacitors, and sensors to discharge and the system to stabilize.
3. Inspect For Issues: Smell for gas, look for visible wiring damage, and check for obstructions near vents.
4. Press The Reset Button: Firmly press and release the button; do not hold it down for extended periods.
5. Restore Power And Monitor: Turn power back on and observe the ignition sequence and blower operation for a full cycle.

If the furnace fails to start or trips again, do not keep pressing the reset button. Repeated resets indicate a deeper issue that requires inspection.

Common Reasons The Reset Button Trips On Gibson Furnaces

Understanding why the reset trips helps target repairs and avoid repeated lockouts. The reset often responds to safety triggers or control faults rather than routine maintenance items.

• Flame Failure Or Ignition Problems: Failed ignitor, clogged burner, or improper gas pressure can cause a flame safety device to open the circuit.
• Blocked Venting Or Exhaust: A clogged or capped vent prevents proper draft, triggering pressure switch or limit switch lockouts.
• Limit Switch Or Overheat Condition: Restricted airflow from dirty filters or closed registers causes overheating and trips the high-limit switch.
• Faulty Pressure Switch Or Inducer Motor: Pressure switch failures or an inoperative inducer motor will stop the safety sequence.
• Electrical Supply Issues: Voltage dips, blown fuses, or intermittent power can trip controls and require a reset.

Troubleshooting When The Gibson Furnace Reset Button Won’t Hold

When a reset completes but the furnace immediately trips or fails to run, follow a methodical troubleshooting process to identify the root cause.

Quick Diagnostic Checklist

• Check Airflow: Replace or clean the air filter and ensure supply and return vents are open.
• Inspect The Flame Sensor: A dirty flame sensor can cause false flame failure; clean gently with fine steel wool.
• Verify Gas Supply: Confirm the gas valve is open and other gas appliances work; if unsure, call the gas utility.
• Examine The Venting System: Look for bird nests, debris, or disconnected vent pipes that interrupt exhaust.
• Test The Inducer And Pressure Switch: Listen for the inducer motor and check tubing for holes or obstructions.

When Electrical Or Control Components Are Suspected

If basic checks fail, components such as the control board, limit switch, pressure switch, or ignitor may require professional testing with a multimeter. Replace only with manufacturer-specified parts to maintain safety and code compliance.

When Not To Press The Reset Button

The reset button is a recovery tool for transient faults, not a cure for persistent problems. Avoid pressing it in several situations.

• If There Is A Smell Of Gas: Evacuate the area and call the gas company or emergency services rather than resetting.
• Repeated Trips: Continuous lockouts signal underlying mechanical, electrical, or safety failures.
• After Work On Gas Or Electrical Systems: Allow a licensed technician to verify safe operation before restarting.
• If The Furnace Shows Visible Damage: Burn marks, melted wiring, or corrosion require professional inspection.

Maintenance Tips To Prevent Reset Button Trips

Routine maintenance reduces the chance of reset-related disruptions and extends furnace life. Simple tasks address the most common triggers for lockouts.

• Change Or Clean Filters Monthly During Heavy Use: Restricted airflow causes overheating and trips the high-limit switch.
• Schedule Annual Professional Tune-Ups: A technician will inspect combustion, venting, controls, and safety switches.
• Clean Flame Sensors And Burners Annually: Dust and oxidation interfere with ignition and flame sensing.
• Keep Vents And Intake Areas Clear: Ensure outdoor intake and exhaust openings are unobstructed by foliage or debris.
• Test Carbon Monoxide Detectors Regularly: Although not a reset issue, CO alarms are essential when combustion appliances operate.

How To Identify If The Reset Button Is Faulty

A defective reset button can fail to reset or cause intermittent behavior. Identifying a faulty reset requires careful observation and basic testing.

Signs Of A Faulty Reset

• The Button Feels Loose Or Stuck: Physical damage or wear indicates replacement is needed.
• No Response After Power Cycle: If the furnace won’t respond after a proper power-off and reset sequence, the switch may be bad.
• Intermittent Operation: Random trips unrelated to known triggers can point to electrical contact issues.

Testing involves confirming power to and from the reset switch with a multimeter and replacing the switch or control module if it fails continuity testing. This work is best left to a qualified technician to ensure electrical safety.

Replacement Parts And Professional Repair

When repairs are necessary, use OEM Gibson parts or equivalent replacements specified for the model number. Incorrect parts can create safety hazards and violate warranty terms.

Finding The Correct Part

• Locate The Furnace Model And Serial Number: This information appears on the furnace service panel or nameplate.
• Order OEM Parts From Authorized Dealers: Authorized dealers provide correct control boards, switches, and gas valve components.
• Keep Records Of Maintenance And Replacements: Documentation helps technicians diagnose recurring issues and supports warranty claims.

When To Call A Licensed Technician

Professional service is recommended in any of the following situations to protect safety and comply with codes.

• Repeated Reset Button Trips Or Persistent Lockouts
• Smell Of Gas Or Suspected Leaks
• Electrical Burns, Sparks, Or Tripped Breakers Related To The Furnace
• Failure Of Ignition After Proper Reset Procedure
• Replacement Of Control Board, Gas Valve, Or Major Components

Key Safety Reminders

Resetting a furnace is a simple fix only when the underlying issue is transient and nonhazardous. Always prioritize safety and adhere to these reminders:

• Turn Off Power Before Accessing Internal Components.
• Do Not Reset Repeatedly.
• Evacuate And Call Professionals If There Is A Gas Odor.
• Use Qualified Technicians For Electrical Or Gas System Repairs.
