Turning a mini fridge into a mini freezer

[bionicbelly]

Hey all.
I am going to start storing frozen yeast, and I want to use a mini fridge to keep my vials in.
I know it will get pretty cold, as in it has the capability to freeze pretty hard, but I want to make sure I can get it down to around -20C (-4F). I have some inkbird 308's, and was going to use one for this fridge. But, I am not sure if this will work, since the thermostat for the fridge will probably kick in at a lower temp than what I want.
Is there a way to disable the thermostat, and rely solely on the inkbird?
I'm sorry if this is a dumb question, I know absolutely nothing about refrigerators.

Why not just get a mini freezer like this one??

Cause I have a mini fridge.

I found this. Easier than I thought.

If you can gently tilt the freezer plate so that it is flush with the back of the freezer, that will turn the entire fridge into a freezer. I did it to one once to convert it into a ferm chamber.

You have to do it slow & gently because if the refrigeration line kinks or breaks, it will ruin the fridge.

I don’t know the max lower temperature.

Any tips on doing this other than going slow?

That’s about all I got.

if it starts to resist, stop and let go. It will spring back a little. Then try again. You might have to do that several times to get it all the way back.

mine was held in place with 4 screws: 2 front & 2 back, that fixed the plate into the side walls. I removed the screws and slowly and gently tilted it until I had the plate close to the back.

I’ve done it twice to this fridge. I don’t dare do it again.
