Furnace pilot light repeatedly extinguishes due to gas valve malfunction, leaving homeowners without heat

Homeowners experience intermittent heating failures when their furnace gas valve opens unexpectedly, causing the pilot light to go out and the system to stop working. This is particularly painful during winter months when lack of heat becomes an emergency. Current DIY solutions and generic HVAC advice fail to address the root cause, forcing expensive emergency service calls or complete furnace replacement.
