What Is The Suburban RV Furnace Reset Button?

The reset button on a Suburban RV furnace is designed as a safety feature to stop the furnace when an unsafe condition is detected, such as flame loss or overheating. Pressing the reset button restarts the furnace’s ignition sequence, allowing it to attempt lighting again. This button ensures that the furnace does not continue to operate under hazardous circumstances and helps prevent damage or fire risks.

Where To Find The Reset Button On A Suburban RV Furnace

The reset button is typically located behind the furnace burner access cover or on the furnace control box. It is often red or black and somewhat recessed to prevent accidental pressing. Accessing it requires removing the furnace cover, which should be done carefully to avoid damaging components. Consult the Suburban furnace manual to verify the exact location for your furnace model.

When To Use The Reset Button On The Suburban Furnace

Using the reset button is appropriate when the furnace fails to ignite or after it has shut off due to an error condition. Common scenarios include:

Burner ignition failure
Flame sensor issues
Thermocouple or thermopile fault causing safety shutdown
Air pressure switch detecting obstructed airflow
Sudden furnace turn-off triggered by system safeguards

Resetting the furnace helps restore normal operation, but pressing it repeatedly without addressing the underlying problem can cause further damage.

Step-By-Step Guide To Reset Your Suburban RV Furnace

Turn off the furnace and set the thermostat to off.
Wait for approximately 5 minutes to allow the furnace to cool and reset internal sensors.
Remove the furnace access panel carefully.
Locate the reset button, usually red or black and slightly recessed.
Press the reset button once firmly and release.
Replace the access panel and turn on the thermostat.
Observe the furnace to ensure it ignites properly and runs smoothly.

Only press the reset button once per attempt to avoid flooding the system with gas or damaging components.

Common Issues That Require Using The Reset Button

Thermocouple or Thermopile Failure

The thermocouple detects the pilot flame and signals safe operation. If it fails or gets dirty, the furnace may shut down and require a reset to try ignition again. Cleaning or replacing the thermocouple often resolves this issue.

Ignition Problems

If the furnace’s spark igniter isn’t producing a flame, the reset button can be used after verifying gas supply and vent clearance. Persistent ignition failure suggests deeper electrical or gas valve issues.

Clogged Air Pressure Switch

The air pressure switch monitors combustion air flow. Blockages in furnace vents or drains can trigger safety shutdowns, necessitating the use of the reset button after clearing the obstruction.

Safety Precautions When Resetting Your Suburban Furnace

Ensure proper ventilation: Confirm that vents and flues are unobstructed before resetting.
Check for gas leaks: Smell for gas odors and inspect connections thoroughly.
Do not overuse the reset button: Continuous pressing can be dangerous and worsen furnace damage.
Follow the manufacturer’s guidelines: Refer to your specific Suburban furnace manual for instructions and warnings.
Turn off all electrical sources: When handling furnace components, ensure power is off to avoid shocks.

Tips For Maintaining Your Suburban RV Furnace To Avoid Reset Issues

Perform regular cleaning: Clear dust, dirt, and debris from the burner assembly and pilot light area.
Inspect gas lines and connections: Periodically check for leaks or corrosion.
Test safety switches: Ensure pressure and flame sensors work correctly.
Maintain venting systems: Clean ducts and clear any blockages in exhaust and intake vents.
Schedule professional inspections: Annual servicing by RV technicians can catch problems early.

How To Troubleshoot If Resetting Does Not Work

If the furnace continues to fail after pressing the reset button, investigate these areas:

Gas Supply: Verify the propane tank has sufficient fuel and the valve is open.
Ignition System: Inspect igniter and wiring for damage or corrosion.
Thermocouple Condition: Replace if the sensor is worn or faulty.
Air Pressure Switch: Check for blockages or faulty switch components.

Consulting a certified RV technician is advisable when problems persist to ensure safety and proper repairs.

Frequently Asked Questions About Suburban RV Furnace Reset Button

Is it safe to press the reset button multiple times?
