Problem: Missing feet
Fix: Turn unit over. There should be 5 feet. On older models it’s a 1/2” diameter white rubber foot. On newer models it’s a 1” beige nylon pad. If 1 foot is missing I suggest you replace all 5. Note: you can replace with either 1/2” or 1” models. I suggest the 1” pad, it’s more stable. Just pull out old ones and press in new ones. Can order on Amazon
