I'm in a bit of a predicament with my refrigerator. It suddenly stopped cooling, and I'm not sure what to do. The light is on, so it's getting power, but there's no sound of the motor or cooling action. I've checked the obvious things like the power source and settings, but no luck. I have a lot of perishables at risk, so I need to figure this out fast. Does anyone have any ideas on what could be wrong or what steps I should take next?

Thanks for the tips! I tried unplugging and cleaning the coils, but it didn't change anything. It looks like I might need to get a professional to check it out. I'm worried about the potential cost of repairs or having to buy a new fridge.
