Re-lighting your pilot flame

Keeping this in view, can a furnace gas valve be repaired?
Furnace gas valves occasionally stop opening and closing properly with age. Sometimes cleaning or repairing them can restore their operation, but when that doesn't work, replacement is the only option. Gas valves aren't repaired often because the labor cost would push the price past the cost of a new part.
Why do gas valves fail?
A diaphragm connected to a valve controls gas flow and pressure. A thermocouple senses heat from a pilot flame and generates a current that holds open a solenoid valve. Gas valves can fail from a variety of causes including contamina- tion, product deficiency, and misuse.
