Minecraft wiki entry for Furniture, associated text: Once you pick a spot along a wall where the fridge is going to go, dig a two-block deep hole and place one iron block at the bottom of it. Next, put the chest inside that hole, then destroy the three blocks behind, left, and right of the chest. replace those blocks with iron blocks. Next, place an iron block two spaces up (if you place a solid block directly on top of the chest it won't open, therefore, make one space between the chest and the iron block). Optional: At this point, you can place an upside-down quartz stair on the iron block. Since the quartz stair is not a solid block, the chest can still be accessed. However, the quartz stair will not match the iron blocks, so they may need to be replaced by quartz blocks, but they will still not match the iron door. If you do not plan to use the quartz stair, place an iron block on top of the iron block behind the chest.
