The wr9x330ds timer is made for GE refrigerators, but it is a universal type that I use on most brands as long as it will fit in the space and perform the same. This timer is very reliable. In my opinion, your original timer is not as reliable as proven by service data that I keep.
For exact performance per the old original timer, you can go with the electronic one, but in that case, I would put a 1000 joule surge protector on the wall outlet for the fridge.
