My brother has a Whytner CHC-120S cooling humidor and it is not holding humidity. I emptied it out (approx. 70 cigars) and added 2 Boveda packs (72) and the highest the humidity would get is 59%. This is after letting it run a full day. I then removed all shelving with no change. I simply unplugged the unit and let it sit for a couple of hours. The humidity rose to 85%. I then plugged the unit back in and within an hour or two, the humidity dropped again to 59%. The cooling is working and it has a few condensation drops in the back well. Has anyone seen this problem when the cooling is on it sucks all the humidity out? Also I tried to see if I can locate a control board for it but the site I found one on is temporarily out.
