A:Answer Hi. We had the same reaction last year when we bought ours. It takes some getting used to, and thought it was malfunctioning and went round and round with Zline… but it turns out it is “normal” as there are laws now about cooling fans being mandatory to protect the electronics between your burners and the oven, and keeping the exterior from being to hot to the touch. As soon as we are done cooking we turn the oven off and crack the door to help it cool off and stop blowing faster. On a happier note, it cooks food SO well, and the burners are amazing! Hope that helps!
