By way of explanation: I live in an apartment, so the freezer I use is not mine. It's a stacked freezer/fridge, just about as bog standard as you would anticipate seeing in any home.
Recently I've been thinking that it sounds like it's struggling often. Sometimes it feels like ice cream inside the freezer is a little soft (though that could just be that certain brands of ice cream are softer than others?)
About a week ago, I got home from a weekend vacation and was dead tired. I pulled out some frozen chicken yakisoba for dinner, and several hours later got the worst food poisoning of my life (I should note that the doctor did diagnose it as food poisoning, and specifically blamed something I ate). The people I had been on vacation with didn't suffer any illness, and the last day I hardly ate anything other than breakfast before the yakisoba - so I became even MORE suspicious of the freezer at this time.
I recently purchased a temperature probe and placed it in my freezer. It's only been going about 24 h, so I'm not finished collecting data, but I see the internal temperature of the freezer fluctuating between 2.0 and -6.8 °F. Is this a safe temperature range for a freezer? I've read that keeping it below 0 is ideal, and I'm seeing cycles of 15-20 minutes where it's between 0 and 2 °F. I'm not sure if that's enough, over a longer period, to cause a problem.
I realize this is a bit foolish of me, but I don't want to approach my landlord about replacing the freezer until I'm very sure that there is, in fact, something wrong with it. I just have no idea how to either verify the freezer is safe, or prove that it is malfunctioning.
Thanks in advance for any help.
