How to fix Kenmore stand up freezer after brown out

A week ago, there were several brown-outs and my Kenmore stand-up freezer hasn't been working properly since.

The freezer isn't completely broken. The compressor must still be working, because it does cool down to -3 to -8 Celcius (17-27 F). But, this should be a lot lower. (It is set to coldest, so no, that didn't just get bumped).

I'm wondering how I should go about figuring out what is wrong. My initial guess is that it is not circulating the coolant into the radiator. That's why it is partially cooling, but not fully. How can I confirm this. And what else should I check for?

Finally, is this a problem I should try to fix myself, or should I get an appliance repairman? I have fixed other things around the house, like my microwave, range and humidifier, so I'm not afraid to diy.

Any help would be greatly appreciated.

Thanks in advance.

 

If it’s a self-defrosting model there are a few things you can check for. First, check to see if the fan is running inside the freezer. If not it probably went out when you had the black outs replace it and your problem should be fixed. Another thing look at the back bottom half of the inside of the freezer. If there is excessive frost on the cover you have a defrosting problem. This link is for refrigerator repair but the information applies to your problem Refrigerator Not Cooling Repair Guide
