Symptoms of a Malfunctioning Furnace Gas Valve

A gas furnace is the most efficient way to heat your Denver, NC home. Gas furnaces have long lifespans, and many people find gas heating to be more comfortable than other types of home heating systems. A key part of this type of heating system is the furnace gas valve. The following tips will help you be aware of these symptoms of a malfunctioning gas valve so that you can stay safe and comfortable all winter long in Charlotte, NC.

No Heat

A malfunctioning furnace gas valve may impede your furnace’s ability to perform the combustion process. If the valve isn’t allowing enough gas to get into the combustion chamber, your furnace won’t be able to transfer heat through the heat exchanger, into the air handler, and throughout your home. The result will be room-temperature air blowing from your home’s vents.

Constant Furnace Cycling

Inadequate gas flow from the valve may cause your furnace to stay on for an extended period of time. Without enough gas for the combustion process, the furnace will never make enough heat to reach the temperature setting on your thermostat. The thermostat will continue communicating to the furnace to stay on. Eventually, this could cause the blower motor to overheat. If your furnace doesn’t turn off and it’s blowing room-temperature air, it’s best to turn it off and call for professional HVAC repairs.

Carbon Monoxide Alarm

A failing furnace gas valve could result in a gas leak in your home. The gas may build up and suddenly release somewhere other than the sealed combustion chamber. If too much gas is released from the valve, the excess may seep out of the combustion chamber and mix with the air you breathe. Excess gas also impedes the combustion process. Your home’s carbon monoxide alarm may sound. This is an emergency and requires urgent repairs, explains the Department of Energy.
