What must be reported as a deficiency when inspecting a gas range?

When inspecting a gas range, the presence of gas leaks is considered a significant safety hazard, and it must be reported as a deficiency. Gas leaks can pose serious risks, including fire and explosion, making it imperative for inspectors to identify and report any signs of leakage.

Moreover, the functionality of the heating elements and burner ignition efficiency also play essential roles in the performance and safety of the appliance. Any issues regarding these functionalities should be noted, especially if they affect the range's operational integrity.

A unit that is missing knobs may affect usability, but it does not present an immediate safety risk associated with gas leakage or operational efficiency. Therefore, while missing knobs may be an inconvenience, it is not categorized as a deficiency that directly threatens the safety of the appliance.

Overall, the most critical aspect to report in a gas range inspection is any sign of gas leaks, as it addresses immediate safety concerns that need to be addressed for the protection of the home and its occupants.
