Model # 75023102

take floor panel out and you will see the ignitor,if it takes longer than 1 minute to lite change it out,if it's faulty it will lite but takes longer than normal and i've seen them burn holes through the tube,if it's good then you'll have to check out the thermostat or sensor or could have a bad board,i looked up the model number but it says it couldn't be found so i don't know what is in your oven but start with ignitor,hope this helps
