This freezer seems to keep it's contents frozen, but the warning light/buzzer stays on, the buzzer sound is defeatable, the temp hovers between 0 and 10 degrees, My feeling is that since it is a frostfree model, that the defrost timer has quit and it is staying in the defrost cycle, as the sides stay warm all the time, in the last few weeks, I had opened it to put some groceries in it, afterwards the buzzer /light activated, but the temp stayed close to or at where it should, and the groceries are frozen, like I stated, I think it is fighting the defrost cycle so that it doesn't quite get to 0 and takes so long to recover....any input ?
