回复：求救!冰箱里不跑冷气了,食物都溶化了,不知哪儿出问题了?

There is a fan hidden in the fridge that blows in cold air from the cooling unit. It may be stuck with dust and fibers. You have to open the panel (typically by removing a few screws)covering it and do some cleaning and lubrication ( I think SAE40 motor oil will do--just apply a little).
