Korean-made (By…LG??), serial number RD700753N, purchased new and installed less than a month ago. New installation with new rigid metal exhaust ducting: vertical from dryer location approx 5 feet, 90-degree bend, then horizontal approx 9 feet, through wall to outside. Short metal flex duct connects dryer to rigid duct.
Dryer seems to work, but metal exhaust duct right at the dryer is oddly cool even when dryer is set on maximum "Antibacterial" heat level. It gets warmish, but not very warm and certainly not as hot as I'm accustomed to.
Is this the new norm, or is there a possible defect or problem here?
