Humidity problems

I am having alot of problems with my humi the humidity will not go below 70 with nothing in it , no beads or nothing
i have a 3 draw 600 count with a glass door it was maintaining 69 all winter once the heat came everything went crazy

1- calibrated the hygrometers
2- tried empty cigar boxes to remove some humidity no good
3- moved it yesterday to my basement that fixed the temp 66 from 75
4- i took all the cigars out and put them in a cooler until i get stabilized
5- i tried dry beads no good
any ideas

Thanks
