Why does my dryer smell like mildew when I use the Refresh option?

I’ve had my dryer 4 years. It just died. Will not purchase again.

Love the different options for what kind of clothes you put in

[This review was collected as part of a promotion.] Great price, love the color and large enough for a mid size family. Excellent customer service by Samsung. Will return for my future purchases.

[This review was collected as part of a promotion.] I have it stacked in my condo. Its a lil bit too tall for a 5'4 person as it appears to be on a different setting lit up due to angle. But i will figure it out!! Got washer and dryer!

[This review was collected as part of a promotion.] Works great and fast, nice large capacity. I own a lot of Samsung products so easy to manage it all with Smarthings. Bundled with washer was best deal hands down over other front loaders.

[This review was collected as part of a promotion.] Bought this dryer with washer to have a matching set. (our old washer and dryer did not match.) Dryer is efficent and holds a large load. Need to set the "dry" setting to "dryer" for a good dry.

[This review was collected as part of a promotion.] Love it! Bought this a month ago with a Samsung washer. Have used with all kinds of laundry - regular, sheets and larger items. This combo has made such a difference - thank you!

[This review was collected as part of a promotion.] I bought my dryer 4 mounts ago and glad I did, the dryer is so fast I can dry 2 loads before my washer is done lol

[This review was collected as part of a promotion.] I purchased this dryer together with a washer and I am very satisfied with the purchase. Very easy to use and extremely efficient.
