Hi, the stacking dryer in my RV is 110-volt electric. I am living in the 1988 RV while I build a house; I don’t know the age of the W/D unit because the RV is previously owned.
After drying a standard-sized load for at least 8 hours, I still have to take the clothes out and hang them all over to finish drying. I don’t even bother putting jeans in. There’s moisture and lint on the door, and lint (some is unusually coarse) is getting by the lint screen such that I had to vacuum out the slot (twice so far) as far as I could reach. I removed the front panel, cleaned out the vent hose (thick layer of lint on the bottom), and checked for blockages to the outside–all clear now. The dryer isn’t working any better, and I’m about to call for service.
