Bluestar RNB366BBSS

SaferProducts.gov consumer incident report 20260625-9B6A5-2147315209. Severity: Incident, No Injury. Product: Bluestar RNB366BBSS (36" RNB Stainless Steel Gas Range). Incident: Description of hazard: The structural oven cavity (liner) of this gas range has developed a crack under normal residential cooking conditions, breaching the oven's thermal barrier. The manufacturer's service department has stated the oven cavity is not a replaceable part, meaning the appliance cannot be repaired. Bluestar suggested that a technician come and verify the crack, and the technician said it is not safe and has never seen this kind of problem before. Because this is a gas appliance, a breach in the oven liner raises serious safety concerns: products of combustion, including carbon monoxide, and high-temperature gases can escape into the appliance insulation and surrounding cabinetry rather than venting normally. I am also concerned about elevated exterior surface temperatures, heat transfer to the adjacent combustible wall, and increased fire risk. The crack represents a structural/metallurgical failure of the core oven chassis on a premium appliance marketed as built to last decades, occurring within approximately 7 years of normal use. Incident/injury: No injury has occurred. I am reporting this as a potential safety hazard. Photos attached: Yes - images of the cracked oven cavity. I am filing this report so that CPSC can track whether other 2019-era BlueStar units show the same structural failure pattern.
