ok the frig will start and freeze and be all normal for 24 or 48 hours and then it just stops freezing u can hear it running and that's all. after it stops cooling i checked the back and the black tank is to hot to touch, so i check the fan clean and blow out all the dirt and fuzz gave it a shot of oil to the fan start it again, everything is groovy and then bam stops cooling this time the tank is cool. so i have a repair guy come and maybe figure it out, he replaces the relay starter switch charges me $175 turns it on and leaves. 4 days later guess what no cold air inside. now i am flipping out i don't have the money to bring someone else out to look at it and replace another part and have it not work. please help me figure this out ty
