Aging in a refrigerator temp question

Perhaps, but you don't get the control over temp variations that you do with an external controller. You also don't have protection in case the fridge skitzes out and tries to freeze your beer. My controller won't let the fridge get too cold even if it tries and if my controller's sensor goes bad, it shuts everything down saving my beer.

 

Instead of a temp controller buy a digital thermometer. I bought one on amazon. It's a digital thermometer that asle reads humidity. It's made for a cigar humador. All you do it pop in a battery and it attaches to the inside of your fridge with a magnet. I can set my fridge using the regular temp controls and the warmest it keeps is around 54. I prefer to cellar at 48 degrees because that is where I like to drink my sours. The thermometer confirms that my fridge only fluctuates by a couple tenths of a degree once I set it where I want.

Costs less than $20 and installs in 2 secs.
