Sounds like you might be dealing with a blocked vent or a fan issue — air isn’t circulating between the freezer and fridge compartments. Sometimes it’s just frost buildup behind the back panel. You could unplug it overnight to defrost, but if it’s still not cooling, better reach out to specialists offering home appliance repair in Orange County, CA https://akappliancerepairca.com/ . They’ll check for sealed system or compressor faults. I once had AK Appliance Repair fix mine, and they handled the freon recharge and fan replacement quickly. It ended up cheaper than replacing the whole unit, which was a huge relief.
