What fridge?
Mine Whirlpool
had a bracket on top that was glued to the bridge and screwed to the wall above the opening. The glue let loose and the fridge damaged the side wall. I don’t think it was attached at all on the bottom but apparently there was one screw through the fridge frame
Into the floor. Of the two front bottom adjuster feet, only one was slightly in any wood. The other had nothing under it at all.
I repositioned the fridge, put the single screw back into the floor, and am adding wood strips (still need to stain) under the adjustable feet. I then used two different types of JB Weld to reattach the bracket to the top of the fridge.
