The refrigerator is an appliance and an ignition source (by definition) within the garage and should be elevated 18 inches above the garage floor.
I was not aware of this, can't say I see this issue on new inspections but could see it on a remodel inspection . Some refrigerator power cords exit the unit above the 18" mark but they have the compressor typically sitting at the floor level, so is there a chance that's where a spark could happen or is that all sealed?
Not sure I've ever seen a refrigerator of chest freezer up 18" off the floor but the gas appliance would have to be there also.
Hummm
