I work on appliances for a living, and I'd suggest if you plan on putting anything into the fridge that is worth something to you, to replace that fan ASAP. You didn't mention if you had planned on doing that or have done it, but it is an inexpensive repair, I do it all the time, and if it failed once, it will again, most likely sooner than later. You can easily find the part online, though the model number doesn't look quite right, Kenmore units usually have 3 numbers, a dot, then a bunch more numbers. The 3 numbers before the dot indicate who made it for them (Whirlpool, Amana, etc), and you'll need them to look up the correct part number for the fan.
Once you get it, search for an evap fan motor. Not expensive, easy to replace, and it will keep your product at the right temp. One important thing to look at once the cover is off and the fridge is running is the frost pattern on the evap. It should cover the whole evap top to bottom evenly. It's easiest to see if you start with a warm freezer, and with the cover off and the fan not blowing, watch as the frost starts forming on the evaporator, it should cover it completely within 3-5 minutes or so, top to bottom. If not, there may be a sealed system issue such as low refrigerant due to a leak. Best of luck!
