On the pipeing to the cooling coil there is a bulb, this controls what they call the superheat (effectively the valve that says how much vapour to release into the coil to give the cooling) just check it hasnt been knocked loose or that the tape holding it in place hasn't come loose.
Also there is sometimes a defrost stat that also has a bulb on it this should be held on a clip behind the coil just check its not come loose, other than that I don't know but 'll think about it
