Ok, I have a Magic Chef 45 bottle unit I got from Home Depot a while back. It is a traditional compressor style unit, so you do hear the compressor and even refrigerant flow at times. Howeverk, periodically, I hear a popping or creaking noise. It dosn't really sound completely mechanical (like the compressor turning on or off), but almost sounds like a creak or pop from the body of the unit. The best I can compare is what you might hear from a traditional TV (tube and plastic cabinet, not rear projection) that well after your turn it off, you might hear a brief creaking pop, which I always figured was the plastic housing creaking as it called with the unit turned off.

I am trying to figure out if this is normal, or if I need to call for warranty repair. Considering we only hear this once or twice a day, I am not sure how easy it will be for the repairman to reproduce and identify what is going on, which is why I decided to post here first.

As to temp changes, in case anyone is wondering, I have a dual temp digital thermometer in the unit. I have a probe near the bottom of the unit and a probe near the top. I have a digital display with memory on top of the refrigerator.

The normal temp is 51* at the bottom of the unit(where I keep my Rieslings) and 54* on top shelf where I keep my reds. The bottom temp probe will range from 49*-53*, over the course of say a week (going by the high and low memory feature), but typically stays at 51*. The top probe is typically 54*, but will range from 53*-64*. I am pretty sure where the 64* comes in is that the unit (even thought it was sold as a wine cooler), had an auto defrost cycle that heats up the back panel periodically to melt any frost that is forming. From what I can tell, this temp rise must be pretty brief, because whenever I check the current temp is is right around 54*, but if I check the memory it has been as high as 64*, and it only the top portion of the fridge gets that hot. I refersed the probes to see if it was a probe malfunctioning, and it wasn't, so I am sure it is the defrost cycle.

Anyway, does this periodic pop/creak that I mentioned sound normal for this type of fridge, or does it sound like a mechanical problem of some kind?

Tnedator,
Pretty sure we have the same unit. I recently upgraded, but still use the magic chef for short term holds. We have had no problems with this unit for the 3 years that we have owned it. Although this will serve the needs of a casual collector, it is by no means a top of the line cooler. Any unit in this price range will have minor fluctuations in temp with variation from top to bottom.
Without hearing the pop, it’s hard to say if my cooler makes similar noise. This is by no means a quiet unit. I hear what could be described as a popping, but the noise is no more pronounced than any other sounds that it makes. I wouldn’t worry. If you start to see dramatic temp increases or rapid vibration, then call for repairs.

I have one of these as well and the Temp fluctuations do not bother me since what you are seeing as fluctuations is the air temp, once the liquid is cooled down there is very little temp fluctuation of the wine itself. What you need to be concerned with is the humidity level, I keep a small bowl of water in the bottom and that works great for me.
Thanks for the replies everyone. I think it is now a sound of the compressor going on and/or off. I heard it this morning, and when I went over to it, I could hear the coolant flowing, which I assume means the compressor is on.

Especially since I lost my receipt, which rules out warranty work, I guess I will just wait and see if it gets worse or the temp starts to flucuate more. Other than the defrost cycle it runs, it seems the temps are fairly stable.
My unit makes noise sometime, not a lot though. I have a KitchenAid unit. I've been pleased with that brand and it costs less than Sub Zero.

LOL, are you literally talking about the sound of a cork being pulled, as in when I drink a bottle, or that the sound is similar to a cork being pulled. The sound is actually fairly similar the pop of a cork being pulled. Not exactly the same, but similar.

I have noticed that my kitchen fridge makes a similar, but much quieter version of the same noise. When sitting in my living room, I can barely here my kitchen fridge make the noise, but the wine fridge that is twice as far away, can be clearly heard. Granted, the kitchen fridge cost 7 or 8 times more, so that might have something to do with how loud the noises are.
Hi, happy 4th. The rain has spoiled the grilling for me. So will do the burgers and hot dogs indoors on this rainy AR day. My wine will comfort me Big Grin
