3 min read Updated: August 4, 2026 By JennAir Support Center

Turn off power before inspecting. Unplug your range or flip the breaker at the electrical panel. For gas ranges, also shut off the gas supply valve.

Important Safety Warnings

Turn off power before inspecting. Unplug your range or flip the breaker at the electrical panel. For gas ranges, also shut off the gas supply valve. Never work on heating elements or internal components with the power still connected.

Know your limits. If a step involves removing panels, testing electrical components with a multimeter, or working with gas lines, that is a job for a certified technician. When in doubt, stop and call a pro.
