Right on crappie14. Years ago i was using a turkey fryer to fryfish. And i had it heating up on the deck while I was cooking some other things in the house. I couldn't get the oil to heat up. every time i checked it, it still wasn't 350 yet. Well I turned it up all the way and was standing there looking at it when POOF it went up in flames. I was in shorts and sandels I went to the truck and put on my fire gear and yelled to the wife to get me a pizza pan preferably one you don't want anymore. I did burn a spot on the deck but I saved the house. So yes check the thermometer!
