Gas geyser pilot light problems: causes and fixes
The pilot light is the small flame that lights your geyser’s main burner. If it goes out, the geyser stops heating and stays off until it is relit. In Pakistan the usual causes are gas load shedding, low pressure and wind, followed by a dirty pilot jet or a worn thermocouple.
