first thing you might want to do is check the seal on the door, alignment might have shifted during the move. second IIRC that humi has a analog hygrometer which are not very accurate, have you calibrated it lately? might want to invest in a digital one.
might want to pull out that bottom shelf and throw some beads in there...way better then the foam trays
HCM BEADS is what i use
Heartfelt Beads and some people use these
hope this helps a little. i know more people with more experience will offer more tips to help you out.
