Gas valve is not opening on the Goodman furnace
The gas valve is supposed to open after the furnace has reached a certain temperature.
The most common cause for this is when there’s a clog in the venting. This prevents the flow of air from reaching the burner and will cause it to push open if it reaches its set point.
If that happens, you need to clean out any debris in your system by blowing air through them or using a vacuum cleaner attachment to suck up any dirt or lint that could be blocking airflow.
The Goodman gas valve helps control the flow of natural gas and air into the burner by opening and closing an opening called a port. The port has a specific size that is determined by the size of pipe feeding it.
The Goodman model includes two main parts in its construction:
1) A piping system, and 2) The burner assembly system. The two systems work together to create heat as well as airflow that makes it easier to regulate temperature levels within your home.
The gas valve is a mechanical device which controls the supply of natural gas to the burners. It creates an opening in the flow of natural gas, in order to maintain the pressure inside the furnace.
A common problem with Goodman furnaces is that the gas valve might not open, which means it cannot provide essential gas to keep the furnace going.
It is important for homeowners to identify if this is a problem with their pressure regulator or if it’s something more serious like a damaged control board or faulty sensor, as these are not easy fixes and require professional intervention.
