If that doesn't work, I'll have the fridge taken away.
You are stumbling around in the dark and you're going to hurt yourself. You have no idea how it works, much less why it doesn't work. You don't even know what tools are involved, much less how to use them. There are several possible causes, the least likely of which is a 'shot of *****', which you are obviously unqualified to add.

Save yourself a lot of aggravation and probable injury. Have it taken away.
