How Do You Know If Your Furnace's Gas Valve Is Failing?
It's no secret that gas furnaces involve fire. The heat in your home comes from the combustion of natural gas inside the furnace's burner chamber. This process requires a specific amount of gas to enter the chamber, allowing the furnace to burn cleanly and efficiently. Too much or too little gas can cause severe problems or inefficient operation. The gas valve regulates the flow of fuel to the burners. The valve remains closed most of the time but opens when the thermostat requests heat.
