Mitsubishi MSY-D30NA Gas Valve
The main job of a gas valve is that it controls all of the gas as it comes into the furnace. This gas valve is probably ran by the control board which is affixed to the main HVAC system, if you have one.
Indications of a weakening valve that controls the gas
- System refuses to start
- Furnace will not light
- The valve looks damaged
- You smell gas
