Smoke coming out of your oven at high temperatures can be a sign of several issues. One common reason is the buildup of food residue or grease on the oven walls or heating elements. As the temperature increases, this residue can burn and produce smoke. To prevent this, make sure to regularly clean your oven and remove any food particles or grease. Another possible reason for smoke is that you may have accidentally spilled something inside the oven, such as oil or sauce, which is now burning when exposed to high heat. In this case, cleaning up any spills promptly and thoroughly is important to avoid smoke and potential fire hazards. In some cases, smoke coming from an oven could indicate a more serious problem, such as a malfunctioning heating element or faulty wiring. If you have cleaned your oven and there are no spills present, but you still notice smoke at high temperatures, it’s best to contact a professional technician to inspect and repair your oven to ensure its safety and proper functionality.
