I need to purchase a small freezer and the only space I have for it is in an unheated, insulated attached garage. I recently moved to the Dakota's where the weather can get quite cold. I am receiving conflicting information from friends, some say it is OK, others say the cold weather will cause the freezer to stop running because lubricating oils and/ or compressor will fail and others say only a manual defrost is OK. I have checked manufacturer's sites and cannot find this problem addressed. Your opinion? Thanks.
Refrigeration units don't care for the most part how cold it gets with exceptions. The oil is not a concern, neither is manual or auto defrost. Refrigeration units that are required to operate in cold temperatures, say below 30 degrees F. have crankcase heaters on them to heat the oil which keeps freon moving out of the oil and the bottom of the compressor. Otherwise when the compressor starts the cold freon will we sucked out of the bottom of the compress with a large quantity of oil which can destroy the compressor. Another item used for cold weather application is a fan control sensor which keeps the condensing temperature up or the unit will again remove the oil from the crankcase. It may work fine for a quite a while, but it will fail in continuously cold temperatures.

No. There are units designed to operate in a garage. These units are pretty expensive. The drastic change in temperature tricks the sensing components. You have a good chance of loosing your food product in the unit. As a former service technician, if the call was for a unit in a garage, we would contact the customer, explain the situation and cancel the call.
The first thing is to find out if there is a fan that runs next to the compressor. If not then in the summer the machine is overheating and passing the heat up to the machine itself thawing or preventing the freezer from operation properly
Hi: It sounds like you bought a frost free freezer as it has a fan. The fan will come on to circulate the air. It will not necessarly run continuosly. The noise is most likely coming from the fan. I sold Frigidaire freezers for years and they are noisy compared to a refridgerator. If you think it is louder than it was when you bought it, I would replace the circulating fan. Also look at the back wall for frost as it could be a bad defrost heater blocking it with ice. Most likely just the fan though. Since it's in a detached garage,and you won't have to put up with the noise inside your house, it could run a while before failing. The fact it's getting cold is a very good sign.Also as you asked 2'nd, a freezer is ok in an unheated garage. Don't put a refrigerator in there. Unless It is a Whirlpoll Gladiator that is designed for such applications. Use www.searspartsdirect.com to find out where the fan is if you feel it is necessary to replace it. Its not a tough job if you are handy. Their shipping is expensive so you might want to buy it locally.
If the door is not sealing because of frost build up or product blocking it it won't make the noise. Is it still cooling ok? If you haven't defrosted it you might do this now. Is it in a cold location, i.e. unheated garage up north? This can cause it also. Check the door and the cooling first if it's not right I would call for service. You should have a one year warrany.
