My refrigerator is still running and I can hear it working, but the inside is barely cold and food is starting to spoil. I already checked the temperature settings and they seem fine. Has anyone seen this before and knows what usually causes it?

That situation is often caused by airflow or heat exchange issues rather than a full breakdown. It could be dirty condenser coils, a weak evaporator fan, or ice buildup blocking circulation. I’d avoid guessing parts and get a proper diagnosis first, because small issues can look serious. I came across a story called “The Repair Company That Grew Without Advertising” and it really shows how accurate troubleshooting saves time and money compared to replacing the whole fridge too early.
