The 'Haier' model's refrigeration compartment is only 45 or below when set to highest cold setting for refrigerator compartment and the freezer is set to it's coldest setting as well.

The unit seems to be acting as if it is freezing up for lack of refrigerant gas or some other cause. Ice build up, although not visually apparent for the unit is full of frozen food, causing interference (not the food) with the fan and the surrounding plastic back wall seems to be the source of the noise. Depressing the back wall of the freezer compartment on the left or right side about the location of the fan, sometimes suppresses the noise entirely, even when released (at times).

I have considered the thaw cycle or temperature not operating properly, but with the temperature in the refrigeration not tolerating warmer settings without the temperature rising to 55+ degrees; I more or less seem to doubt this as a likely scenario.
Additionally, re. the defrost cycle, there is no apparent interior build of ice within the freezer compartment at anytime.

I enjoy troubleshooting, but I am novice with some intermediate skill level, would anyone care to offer some other opinions or suggestions?

Here's some additional info on the Haier unit for it wasn't listed in the 'down-arrow menu' on this forum.

Thank you in advance for all your help, Nic:)

Thank you Denman.
Would your thoughts towards defrost be the same if I said this condition was more than 8 months or better and ongoing? Or would you suspect anything else?
It may also be worth noting that the unit has some external damage to doors; the owner said it was reduced in price for this reason.
I am still considering your view, I was also wondering what values one might expect to find with the low or high pressure sides?
Thank you in advance.

Hi Denman:)
I was afraid to do too much because we were uncertain if a warranty applied at the time. As it turned out, a warranty was in effect and the unit supposedly could not be repaired and so a store credit was issued. I was told that Haier (made in Korea) and many other models that were made overseas were a bit of risk in terms of actually finding OEM parts. So if a unit was at some point in need of a repair, a universal part would essentially be your only alternative if even available.
As for what was wrong with the unit, the warranty repair services didn't do anything except note the brand say, 'Can't be fixed or get parts.'
I have heard that before and although that may be true in this case, at times I can still track down parts through my parts rep. that others tell me can't be had. I usually give tell them where they can it if I do find it. :)

Thanks again,
Nic:)
Thanks again and I am sorry for such a long delay in a follow up.
