I'm having a problem with my refrigerator/freezer that I can't quite figure out. I rent an apartment so I'm not exactly sure how old this model is but I don't think it's older than 10 years as it has a Power Saver feature. For the past 2 years that I've lived here I always kept the settings as follows: Refrigerator 1.5 out of 9, 9 being coldest; Freezer A , E being coldest; Power Saver turned on. I've never had a problem before, food stayed frozen in the freezer and cold in the refrigerator. It cycled like it was supposed to and I didn't notice any problems. Now all of a sudden after getting an outrageous electric bill I discovered that my refrigerator/freezer isn't working properly (I think). It is running non-stop around the clock. I checked under it and behind it to see if it was dirty and it doesn't appear to be. I unplugged it from the wall and plugged it back in. There is no frost build-up in the freezer but it is mighty cold. The refrigerator is quite cold too, not so cold as to freeze my milk but pretty cold. I tried changing the Power Saver setting but that didn't seem to help. I turned the temperature setting all the way down to 1 or 0 and that didn't seem to help either, still kept running. It did finally shut off but that was only after I turned the dial to off so I don't think that was much help. I kept the setting on off for now until I can figure out what is going on. Any advice or opinions? Should I bother with this or just have my apartment complex come look at it?

Measure the freezer back wall temperature and post, you might have other problems.

You may well have fixed it, only time will tell.
