How to replace old Roper oven with slightly newer Jenn-Air

I have a 4 year old Kitchenaid refrigerator and the freezer is not holding temp. Model KRFF 305EBS00. We had a power outage a few days ago and i ran the frig on my Honda 2000 watt generator for about 24 hours. The main part of the frig (it's a french door style) holds temp at 38°, but the freezer, which is set to hold at 0°, varies and is up as high as 10°. Any advice? Thanks

Just in case this helps someone out there... This I'll call a workaround and perhaps a tip. My dishwasher is a Frigidaire Gallery lgid2475qf3a. I inherited it with the house I bought. (Yes, thank you. I appreciate your sympathy and condolences. ;-) Anyway, my experience with this was awful/terrible/pathetic, I daydreamed of running it over with a monster truck. Then I made a discovery. If you run cleaner through it monthly, you can *almost* make it function like a good dishwasher. (Let me compare this to the low-to-medium priced Kenmore dishwasher in my previous house, which cleaned pretty well, and I never *HAD* to clean it to make it work properly. That's how it should be.) As a noted cheapskate, I have discovered that using Iron-Out (or other calcium deposit descaler products) is an economical way to clean it, rather than buying things labeled as dishwasher cleaners, which although convenient, you get maybe two cleaners for about five dollars, whereas the big container of Iron-Out costs maybe $12, but it'll clean the dishwasher monthly probably for two years. What I do: - NO METAL! Ideally, run the dishwasher empty, but if you want, you can multitask, and run a load of dishes (Dishes only, glass/stoneware/etc., and plastics too, but no metal, let me repeat, NO METAL. - Per the instructions that came with the dishwasher, stand nearby and listen for the first time the dishwasher drains, roughly ten minutes or so after you start it. (You'll hear water gushing down the drain three times within about a minute's elapsed time.) THEN, open the door and pour some of the cleaner in it. I don't really measure carefully, I'm going to guess I put about a half cup into the dishwasher. - Hint - Iron Out isn't the greatest smelling thing in the whole world. However, at least with this dishwasher, you don't really smell it as the dishwasher runs, and after the cycle is over. If you decide to try it with some other brand/model dishwasher, I can't guarantee that you may not smell it as you clean your dishwasher. If you're worried, pay more money for a dishwasher cleaner. - Run the long cycle, perhaps twice when you do it for the first time. And for about a month, this awful dishwasher will do an OK job washing dishes. Then a month later, you'll start noticing it's not washing well, meaning it's time to clean it again. As I mentioned, my previous dishwashers did an OK job for years and years and didn't need to be cleaned monthly in order to work. Those were good dishwashers. This one, well, it's shiny. I can't think of much else good to say about it. But, until I get the Monster Truck and the replacement dishwasher, I'm able to tolerate this dishwasher by cleaning it monthly. Hope this helps someone out there.
