4. What is a Honeywell Gas Control Valve
A Honeywell gas control valve is a safety and regulation device used in gas-powered systems like water heaters and furnaces. It
controls the flow of gas to the burner, maintains proper temperature through integrated thermostats, and ensures safety by
shutting off gas if a flame is not detected. These valves may be mechanical or electronic and are known for their durability,
precision, and compatibility with residential and commercial heating systems. Honeywell¾s gas control valves are widely trusted
in HVAC applications for providing reliable ignition control, temperature regulation, and enhanced safety.

5. How Does a Honeywell Gas Control Valve Work
Receives a signal from the thermostat when heating is required
Opens the gas valve to allow gas flow to the burner
Ignites the gas using a pilot flame or electronic ignition system
Flame sensor detects ignition and confirms safe burner operation
Continuously regulates gas flow to maintain the desired temperature
Automatically shuts off gas if no flame is detected or once the target temperature is reached
Prevents gas leaks or overheating through integrated safety mechanisms

6. Importance of Resetting Honeywell Gas Control Valve s
Honeywell gas control valves may need resetting due to issues like power surges, dirty parts, overheating, or safety shutdowns.
Resetting helps restore normal system function.
Resetting a Honeywell gas control valve is crucial for several reasons:
1Restoring gas flow
A reset can help reopen the gas
line, allowing the system to
begin heating or providing hot
water again.
2Troubleshooting
system issues
Sometimes, the valve might be
stuck in an off position due to a
malfunction. A reset can clear
the issue, restoring normal
operation.
3Ensuring safety
Many gas control valves have
built-in safety features that shut
off gas flow if an issue is
detected. Resetting the valve
restores normal, safe operation.

7. Precautions Before Resetting the Gas Control Valve
Turn off the gas supply
Prevents leaks and hazards.
Power off the appliance
Avoids electrical interference.
Check for leaks
Don¾t reset if a leak is suspected.
Check the user manual
Follow model-specific instructions.

water heater, HVAC boiler system.

9. Steps to Reset Honeywell Gas
Control Valve on a Furnace

10. Resetting the Honeywell furnace gas control valve is generally a simple process. Here are the steps to follow:
Turn off the furnace: Begin by turning off your furnace. This will ensure the appliance is not actively running during the reset
process.
1.
Locate the gas control valve: The gas control valve is typically located near the gas line and the furnace burner. Look for a
knob or dial marked with settings like <OFF,= <PILOT,= and <ON.=
2.
Turn the valve to the <OFF= position: Rotate the control valve to the <OFF= position and wait for at least five minutes. This
allows any unburned gas in the system to dissipate, ensuring safety before you proceed.
3.
Switch the valve to the <PILOT= position: After waiting, turn the valve to the <PILOT= position. You will likely hear a click as
the valve engages.
4.
Light the pilot light: Using a match or lighter, light the pilot light. Keep the flame near the pilot assembly until it ignites.5.
Set the valve to <ON=: Once the pilot light is lit, turn the gas control valve to the <ON= position to restore normal operation.6.
Turn the furnace back on: Finally, power up your furnace again and test for proper function.7.

11. Steps to Reset Honeywell Gas
Control Valve on a Water Heater

12. The reset procedure for a Honeywell water heater gas control valve is similar but slightly different. Here¾s how to reset it:
Turn off the power and gas supply: Start by shutting off the gas supply and disconnecting the power to the water heater.1.
Locate the reset button: For many Honeywell water heater models, there will be a honeywell water heater reset button
located on the gas control valve. This is typically a small, red button.
2.
Press the reset button: Press the honeywell water heater reset button firmly. You should hear a click as the reset process
engages.
3.
Check the status light: After resetting, check the honeywell water heater status light. If the light is flashing or solid, it
indicates that the system has reset successfully. Refer to the honeywell water heater status light codes in the manual to
interpret the light pattern.
4.
Restore the gas supply: Once the valve is reset, turn the gas supply back on and wait for the water heater to begin heating.5.
Power up the water heater: After the gas supply is restored, turn the power back on and test the system.6.

System

14. Resetting a Honeywell boiler gas control valve is also a relatively straightforward process. Follow these steps to reset the valve on
your HVAC system:
Turn off the boiler: Begin by turning off the HVAC boiler system and cutting off the gas supply.1.
Locate the gas control valve: Find the gas control valve, typically located near the burner or combustion chamber.2.
Turn the valve to <OFF=: Switch the gas control valve to the <OFF= position and wait for about five minutes to ensure any
residual gas has dissipated.
3.
Turn the valve to <PILOT=: Rotate the valve to the <PILOT= position.4.
Ignite the pilot light: Light the pilot light carefully with a match or lighter. Hold the flame near the pilot until it ignites.5.
Switch the valve to <ON=: After the pilot light is on, move the gas control valve to the <ON= position to restore the gas flow.6.
Power up the system: Finally, turn the power back on and test the boiler to ensure proper function.7.

15. Troubleshooting Common Problems After Resetting
After resetting your Honeywell gas control valve, you might encounter a few issues. Here are some common Honeywell gas
control valve problems and how to troubleshoot them:
1 No gas flow
If your system doesn¾t seem to be receiving gas, check the gas supply to make sure it¾s turned on. Also, inspect the
Honeywell gas control valve for any blockages or damage.
2 No pilot light
If the pilot light won¾t stay lit after pressing the reset button, the Honeywell furnace gas control valve or water heater
gas control valve may be faulty. You may need a Honeywell gas control valve replacement.
3 Flashing status light
If the Honeywell water heater status light isn¾t blinking or flashes continuously, it may signal a thermostat or gas issue.
Refer to the troubleshooting guide for help.
