I have an upright freezer (Maytag) that's 2 years old. It used to work very quetly and with cool exterior for the past 2 years but in the last ~5 weeks, the sides / top are hot all the time (105 degrees F) and the freezer is running very loud. The environment is the same as it was before and the freezer is ~85% full (which is pretty constant). The freezer door is opened 2-3 times a day for a few seconds.
I had a warranty technician look at it, he didn't do anything other than telling me that this is how it's supposed to work. (I know freezers have to dump heat on the inside to freeze food but it seems unnecessary that it does this 10 hours a day every day.)
Does this sound correct or is it the case of a lazy technician? (He came without tools so he had no intention of repairing anything.)
