I was in earlier today. It appears that the compressor is kicking on without the fan or the display. I turned it on and the fan came on and it began to cool so I turned it back off and it persisted with a loud pumping sound over the next 30 minutes that sounded like a compressor. I unplugged it. Then next time one of y’all is in the building can you listen to it as well and tell me what you experience?
