Hello there! I completely understand your concern about seeing white smoke while trying to get your weekly meal prep done, especially with a new batch of pork.
Most of the time, white smoke in an air fryer is caused by excess fat or oil dripping down onto the hot heating element or the bottom of the basket and burning off. Since you mentioned the meat was on sale, it might have had a higher fat content or extra trimmings that rendered quickly under high heat.
Your air fryer is likely not broken, but to be safe, I recommend unplugging it, letting it cool completely, and checking the heating element for grease buildup. Cleaning it thoroughly before your next cooking session should resolve the issue.
