Responded to a customer complaint of gas odor when operating the lower oven. Performed comprehensive leak detection along all gas connections to the appliance, finding no evidence of gas leaks. Upon testing the lower oven during operation, detected no gas odor, though customer noted a slight whiff. Determined smell was likely normal combustion during initial ignition rather than a leak. Advised customer that no immediate concerns were found but recommended contacting an appliance specialist if they wanted further investigation of the oven's internal components.
