2011 Passport Refrigerator Temperature Control

[E597283]

I have had issues with setting the temperature in my refrigerator. I have the sticker that says to slide the plastic glide up on the fin for cooler temperature but the refrigerator always takes a while to cool and doesn’t seems to be that cold. I have read on an older thread that the wire with the “large tip” needs to be actually touching and making contact with the fin. Is this correct? I do have it attached to the glide but I am not sure it is actually making contacting with the fine. Why don’t they just have a normal temperature control dial like a normal refrigerator? I assume there are not temperature controls for the freezer?
