Intertherm not cooling correctly

Question

me and a friend just moved into a trailor like 4 months ago. our intertherm cooling system was working at the time now it seems like the outside unit is only blowing out warm air instead of hot air, is it suppose to be hot or warm air, inside the trailor it blows cool air but not cool enough to keep the trailor cool all the time. we just had a block under the power meter blow out would that have been the problem? or is it something else like the freon or what? i'm not sure what they mean by product. our intertherm model is: sch30 ib 82mr25 cr03
