My oven started acting up recently. Food is getting burnt on one side while the other side stays undercooked. I tried changing trays and using different modes, but the issue stays the same. Has anyone dealt with this before and knows what usually causes it?

Uneven heating like that usually points to a weak heating element, poor air circulation, or a temperature sensor that’s no longer reading correctly. It can look serious, but often it’s a single part causing the imbalance. I wouldn’t rush to replace the whole oven yet. I’ve seen similar cases described here https://gdoing.com/the-repair-compan...t-advertising/ where what looked like a major breakdown turned out to be a simple repair after proper diagnosis.
