Garage Refrigerator / Freezers, Winter, and Your Food

Dear Home-Ec 101,
I have a refrigerator in my garage and for the last few weeks I have noticed the freezer isn’t as cold as it should be.
Should I be worried?
More importantly, is the food safe? The vegetables seem a little soft.
Sincerely,
It’s Frickin’ Freezin’ , Mr. Bigglesworth

Garage refrigerators can be very useful for food storage, if you have a bunch of kids, they are also useful to keep the kids from running in and out every time they want a drink.

Unfortunately when the temperature drops below 40°F or 4°C the freezer may not maintain the proper temperature.

Why?

Refrigerators are designed for typical household use. The “average” house is expected to be in the general vicinity of 70°F or 21°C or “room temperature.”

Unless you have a high-end refrigerator freezer combo, which is unlikely in a garage refrigerator scenario, the freezer does not have its own thermostat.

The thermostat in the refrigerator portion of the appliance controls the temperature of the entire unit with the logic being, if the refrigerator portion is 40°F the freezer will be at 30°F or below.

In the winter your garage may be much closer to 40°F. Over time the thermostat in the refrigerator tells the motor, hey, we don’t have to run so often. All is well in the refrigerator portion of the appliance, but that freezer is going to slowly approach the temperature of the garage. There is no thermostat back up in the freezer to say, “Hey, we have a problem here, we should be running more often!”

If the garage temperature is only close to 40°F to 30°F for a day or two, it’s really not going to matter. Refrigerators are very well insulated to keep the cold air inside.

The food in your freezer has been beginning to thaw. If it has been over a short period, this won’t matter food safety-wise. If the freezer has time to thaw completely, you’ll need to follow the guidelines in The Freezer Was Left Open, Now What. (Observing whether or not there are ice crystals etc)

Food that is safe is not always good.

Repeated thaws and freezes will destroy the cells walls of the food destroying the integrity and texture of the food. While it may be perfectly okay to eat, I would understand calling it a loss and starting over with the most compromised ingredients, unless you have recipes where the ingredients are cooked to the point that texture is not an issue.

Sometimes life is a series of annoying lessons; I hope that this one wasn’t too expensive.

    Heather, I’ve enjoyed this site for a few years now, but the addition of the ‘shares’ thingie jutting out on the side gets in the way of reading the articles, and I find I don’t bother reading them. It also gets in the way of commenting, because I have to scroll all the way up to expose the box I have to tick to confirm I’m not a spammer. I can appreciate wanting to make things easier for those who want to share your articles, but there has to be a better way.. because this is too annoying.
