A:AnswerThere is a Warm / Keep Warm feature. This function will maintain an oven temperature of 170 °F. The Warm function will keep cooked food warm for serving up to three hours after cooking has finished. The Warm function may be used without any other cooking operations. The Warm function can be used after cooking has finished using a Timed Cook or a Delayed Timed Cook. ^Daphane
A:AnswerSerial and model number for ranges can be located in different areas. In the majority of cases, the label can be found on the left hand side door of the drawer, behind the oven panel, in the left hand side of the frame of the bottom drawer or beneath the upper lip of the top oven when the door is opened. ^Daphane
A:AnswerAn air fryer circulates the air more rapidly thus speeding up the cooking process. The fan speed is faster on air fry mode than convection. I am sorry, the factory did not provide that information on how long it takes the oven to warm up to the desired temperature. Please seek help in the LG Community Forum, https://lgcommunity.us.com. The LG Community Forum is a great resource for getting help from other LG customers. ^Daphane
