Not so much in the FF but the yogurt on bottom shelf was frozen. I checked temps 4 hours after installing parts. I know it takes 24 hours or more to stablize but thought it was weird the temps were below freezing after that much time plus the defrost timer only shut off for 4 minutes but I'm a noob at this. thanks for helping. I really appreciate it. If I can't figure this out I have to swap it out.
