Fridge not getting cold.

[TexasBorn]

My fridge in the trailer is just a small home unit. The little freezer upper part is like 20* but the lower is around 50*. Do you think it's not cooling off because it's in the hot trailer? Thanks in advance.

How hot is the trailer?

By home unit, do you mean a regular AC plug in fridge with a compressor? If so, could be old/less effective, could be in too confined a space (not enough clearance/ventilation around the fridge) or could be just too hot in the trailer.
