sure - you have all kinds of options -
search temp control, or fermentation chambers -
Each of us could/would probably recommend our own, so look thru all the stuff here and choose how you want to do it.
Popular controllers are Dwyer/Love, Ranco, Johnson, and, the ubiquitous eBay Aquarium Temp Control - which is quite inexpensive, but measures in C not F... (if that's an issue for you). I think the ChiCompany has something that will work as well.
Basically, you end up plugging the fridge into the controller, and the controller will use it's temperature sensor instead of the fridge's sensor, telling it when to turn on and off.
