Does My Goodman Furnace Have A Pilot Light

Any gas furnace uses a pilot light to trigger the burners to heat your home.

Does my goodman furnace have a pilot light.

The pilot light is a small flame that is either lit manually and remains burning. The goodman gas furnace has an automatic ignition system that doesn t require manual lighting of the pilot light. Unlike older pilot lights which have to be lighted by hand automatic pilot lights now commonly found in most home furnaces are regulated by a thermostat and only ignite when needed. They have hsis hot surface ignitors.

When your furnace fails to ignite the first place to look is the pilot light. If the glow ignitor comes on but the furnace doesn t fire up some inspection and troubleshooting can be helpful. A small heat sensing device known as a thermocouple makes sure gas flow is delivered to the main furnace burners only when it is warmed by the pilot light. Some older versions may be spark ignition but still no pilot.

How can i re light it when it goes out it s a question installers often hear from customers. The pilot light on my mom s bryant 394had upflow furnace has gone out. However even many modern furnaces still run pilot lights. When heat is called for the gas valve opens and the pilot light lights the main furnace burners.

The most common reason for this problem is because the pilot light is not on. Most furnaces today don t have pilot lights they have gone to spark ignition which sparks the main burners when heat is called for. The most common part to fail is the hsi. Water heaters gas fireplaces and old gas stoves also often have similar pilot lights.

This is for more efficient as there s no gas being used unless for heat. The pilot light in a furnace that ignites the burners is so much a part of our collective understanding of how gas furnaces work that some homeowners find themselves surprised when they discover their new furnace doesn t need a pilot light. If your furnace has a small round knob on the gas valve with the words off on pilot you have a standing pilot ignition. This is relatively simple technology though not very fuel efficient.

If you have an older gas furnace your heating unit relies on a little blue flame known as a pilot light to ensure ignition of the burners. If gas or propane flow to this pilot light is interrupted even for a moment the pilot light can go out and will need to be relit. This is why your furnace won t turn on. When the furnace lights the glow ignitor starts first and the pilot light automatically ignites.

My mission is simple.
