Heres how; First, turn off the gas in the house so you don’t blow yourself up or cause a disaster, loosen the bottom nut, tap the bottom of the plug upward to loosen the tapered plug, remove the tapered plug, lubricate with a special gas valve grease , and re-install the plug, job done.
Why isn’t my gas valve opening?
Furnace gas valve troubleshooting The gas valve opens right after the ignitor activates. So if you don’t see your ignitor turning on, then your gas valve won’t open either. If your ignitor isn’t even turning on, then it’s likely something else in your furnace that’s the problem. Turn off power to your furnace.
Can a gas valve be repaired?
The gas valve cannot be repaired in the field. Only the gas valve manufacturer or someone certified by the manufacturer of the gas valve can make repairs. Then re-certifying the safety of the gas valve. This also applies to gas valves that have been submerged underwater due to flooding.
Why does a gas valve fail?
The valve itself may have simply worn out or may be damaged due to basement seepage or submersion. Alternately, one of the electronic gas ignition components or a glitch in the safety circuit may be to blame. If your furnace has a standing pilot light, the thermocouple could be worn out.
Do furnace gas valves go bad?
A bad gas valve in a Honeywell appliance such as a water heater or furnace that is powered by natural gas can go bad and affect the performance of the unit. A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all.
How do you open a gas valve?
To turn the gas cylinders on (to open gas cylinder valve), turn the valve handwheel anti-clockwise 2 or 3 turns (do not open hard against the stop). To turn off LPG gas cylinder, turn the round valve handwheel located on top of the cylinder clockwise until snug by hand only (don’t over-tighten).
How do you bleed a gas valve?
While pressing the valve control knob in, press the igniter button repeatedly until the pilot ignites. This could take anywhere from one to 10 minutes to bleed air out of the lines as the gas starts to flow. Once the pilot is lit, continue to press the valve knob inward for 30 seconds before releasing it.
How much does it cost to change a gas valve?
Furnace gas valve prices are $75 to $300 for the part alone or up to $600 for original manufacturer parts (OEM). Gas valve replacement labor costs $125 to $500.Furnace gas valve replacement cost. National average cost $500 Minimum cost $125 Maximum cost $1,000 Average cost range $200 to $800.
How long should a gas valve last?
Gas Valves are routinely checked for 100,000 cycles and are used in equipment that have approximately 15 years life expectancy.
How do you test a gas solenoid valve?
How to Test a Gas Valve Solenoid Coil Unplug the appliance from the wall outlet. Use a flashlight to inspect the interior of the burner assembly. Watch the igniter tip and count the seconds while it remains on. Unplug the appliance from the wall outlet. Set the multimeter to the ohms-times-10 setting.
How do you test a gas control valve?
How to Check the Furnace Gas Valve With a Multimeter Turn off the furnace at the wall control. Take out the bolts in the service panel on the side of the furnace using a nut driver. Pull the wires off the gas valve terminals. Turn the test control on the multimeter to “mV,” which stands for millivolt.
Where should a gas shut off valve be located?
The gas meter and gas service shutoff valve is usually located on the side or in front of the building. If the building has a breezeway, it could be located there.
Are gas control valves interchangeable?
Gas Water Heater Parts – Control Valves Natural and propane water heater gas valves are not interchangeable, so, be sure to order a valve for your type of gas.
Are Honeywell gas valves interchangeable?
Honeywell gas valves — the right choice every time. Notes: All piloted valves have a 1/4″ compression fitting. All the VR valves come set for natural gas, but can be converted to LP gas.
What happens if gas valve goes bad?
If the gas valve is stuck or otherwise malfunctioning, your furnace may shut down completely or just stop delivering warm air. There are other issues that may cause the same symptom, so you need an experienced technician to diagnose the problem and apply the proper repair.
What would cause a gas furnace not to ignite?
The Pilot Light (Faulty Ignition Sensor) The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. This is typically the problem if you can hear your furnace click on but it does not fire up. If the sensor or ignitor is dirty, it will need to be cleaned.
What opens the gas valve on a furnace?
The furnace gas valve operates by electromagnets. The primary valve — also known as the safety valve — supplies gas to the pilot light. The second valve — also known as the main valve — allows gas to flow to the burner trays. The thermocouple (or thermopile) generates the power holds the safety valve open.
How do you know if a valve is open or closed?
Ball valves are perhaps the easiest valve to see if they are open or closed. If the handle on top is parallel to the valve, it’s open. Likewise, if the handle is perpendicular to the top, the valve is closed.
