Oven door not closing properly

That sounds like worn hinges or a loose door spring. Over time, the tension weakens, and even a small misalignment keeps the seal from closing properly. It’s an easy visual check, but replacing hinges can be tricky since you have to remove the door entirely. I’d suggest calling someone who handles home appliance repair in Orange County, CA https://akappliancerepairca.com/ . I used AK Appliance Repair for this once — they replaced both hinges and realigned the gasket in one visit. My oven heats evenly again, and it wasn’t pricey at all.
