In cases like that I’d call a local appliance repair service before even thinking about replacing the oven. A technician can quickly check the heating elements, temperature sensors and control board with proper tools and tell you whether it’s a straightforward fix or something more serious. In many situations a single burned‑out element or a bad relay is all that’s wrong, and fixing it costs much less than buying and installing a new appliance. Plus, a good appliance repair service will give you a clear estimate up front, so you can decide calmly if the repair is worth it or not.
