Close the shut-off valve on the gas line to the oven, as the manual asks; do not open any fitting. If it comes back, it needs a visit. ### What is the first step when a gas Rational displays Service 32.1? Close the shut-off valve on the gas line to the oven, which is Rational's own instruction for this message. Then book a visit; the oven will not cook until a technician has checked the burner. ### Is Service 32.1 on a Rational a gas leak? Not by itself; it reports a burner problem. If you also smell gas, treat it as an emergency: no switches, ventilate, get everyone out and call from outside. ### Why do Rational gas ovens have several burner numbers? The manual lists 32.1 to 32.3 and 33.1 to 33.3 with the same wording. The number tells the technician which burner or which step failed, so read it out exactly when you book. --- **[Read on the site: Rational Service 32.1: the gas burner is not working on a gas iCombi Pro](https://commercialappliancerepair.center/error-codes/rational-service-32-1/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
