We just updated from electric to a gas range. It's a fairly high end Frigidaire, not professional, but a good one. Problem is, my wife insists that she smells gas, usually just after lighting a burner. I can't notice it. This is the first gas appliance we've had in over 40 years. I feel that a tiny hint of gas is normal on ignition. It goes away immediately. I don't want to give up a brand new gas range and buy an electric. Any opinions?
