This is not a one size fits all and since my refrigerator was not a Frigidaire I had to adapt it to my unit but it is working well. We have had temps in the 30's and 40's at night and the fridge is working well in the garage. The only downside that I see is that if you don't remove it in the spring your fridge will run too often and raise your electric bills in the warm months.
