Your pilot light needs to be on whenever you’re using your furnace to heat your home. However, you might decide to turn it off during the summer months, when you don’t need heating.

If you suspect your light switch is faulty, turn off the power to that circuit at the breaker and contact a qualified electrician to remedy the issue.
