Or just an old fridge.

Take a $100 bill and close the fridge door on it and see if it pulls out easily. If it does then you might need a new seal. Go all around the perimeter.

Then get another $100 bill and do the same on the freezer.

If you do need a new seal, each bill should just about cover the cost of parts. Installation is easy.

Only reason I haven’t replaced them is because they are so freaking expensive and I need new shelves and drawers too. By that point it’s almost cheaper to buy a new damn fridge.
