Our fridge door has never popped open, and we have encountered some pretty severe jolts. Last week on I-95 in South Carolina we crossed a bridge approach slab which had settled lower than the bridge. We hit the edge of the bridge very hard at about 63 mph. The bridge was not skewed, so we hit it with both wheels at the same time. Although we heard every pot, pan and dish in the cabinets jump, and every piece of hanging clothing in the rear bedroom closet came off the clothes bar, the fridge door thankfully stayed closed.
