Hmmm......Hemi, you reminded me of a situation 4 years ago with a nearly-crashed 4 month old Kenmore upright 20 cu ft freezer we have. It all started when the temps started climbing in the top of the freezer on my first day off work, and I kept cranking the thermostat. The weird part was, only the upper areas of the freezer were warming up. The bottom foods were still frozen solid and the thermometer was reading -15* down low, +25* up high. My wife or kids mentioned that it was noisy the day before...cause unknown. My first thought was: Noisy, ooooooh crap, the compressor is shelled........now, I'm frantically trying to figure out what plan "A" is, and have no idea what plan "B" could possible entail...never had a freezer crash before...ever.
I finally decided to start emptying the freezer into coolers and come up with a makeshift plan on how to salvage as much of the more expensive items as I could. During this process, I noticed what looked like a missing screw in the lower portion of the freezer where the circulating fan is located. Just an empty hole in the back panel. I grabbed my tool kit and a flashlight and set out to find what the missing screw belonged to. The fan mounting base had the missing screw (actually, broken screw head, the screw was still in the mounting base), and the other of the two screws had vibrated loose, allowing the fan blades to contact the air discharge outlet hole in the panel, hence the noisy freezer.
When I got around to finding the problem, the fan had been stalled overnight and half the next day (no more noise...I'm thinking, yeah right, what noise?), so, yeah, the freezer temps are gonna be strange. The broken screw had obviously been over-torqued during assembly and then failed after a few months in service. Easy fix, just darn glad I was home to catch it.
We kind of got suckered into buying this freezer, as I didn't want any more kenmore appliances in my house. In NE Wyoming, if you own anything requiring tech field service by Sears, you will be waiting a very, very long time. The service tech is a contractor for the last 4 or 5 years now...that's right, they no longer have any local Sears repair techs in this area. What a CROCK! And we wonder why Sears and K-mart are partnered up?
Anyway, the guy will show up, check out your appliance, order parts and says he'll return in about 3 weeks to repair it. When he shows up (usually a week or more late), he finds more problems and needs more parts because he got cocky and thought he'd figured it all out the first visit to your home. So, he orders more parts, and about 2 months after your initial call for waranty service, you MIGHT have a properly working appliance again. We've been through this twice with two different appliances...those appliances are no longer in our home.
I like Craftsman tools for their warranty service which is great...if you break it, call a "reputable" Sears store for a replacement. When it comes in, you exchange it for yours, no questions asked. But, Kenmore no more...for us.
