Safe checks you can do yourself
From the outside, you can confirm the breaker, the position of the gas shut-off valve, that burner caps and heads are seated and dry, that the oven door closes properly and that hood filters are clean. For an induction cooktop, try a different pan and write down any code. Do not open panels or touch gas fittings, and switch the range off at the breaker if you notice burning or sparks.
