I've had that same situation happen to me, but it was because the dropped ceiling sat about an inch above the units. I had to pull the ceiling panels out. Having ice seemed to trump having a pretty ceiling 😅
Nice, at least it wasn't form over function, just someone put up some boxes. It's a constant battle with customers who want to pigeon hole their equipment so it "looks nice". Then wonder why ice production is low or freezers don't maintain temp. Shit's got to breath man!
