Hello,  I sent you an email about 3 weeks ago and have not heard back so I thought I would try this?  I loved my Humidor for the first 3 months!  Everything was working fine and my cigars were very happy!  Since mid September the unit does not hold its temperature?  for the 1st 3 months it stayed at the temp I set , 70F.  Now it goes from 67 to 68F? Even if I set it to 74, which is the max I can set it?  It only goes to 67 or 68, sometimes it goes down to 65 on its own?  I just hope this does not continue because my cigars will damage if the temp stays below 69 for too long?  What can we do about this?  Please get back to me!  Thx,  James
