Is your dryer too warm and heats the laundry room also? Are garments hotter than normal on the cease of the drying cycle? Doesn’t the outdoor exhaust vent flapper open very much, indicating low exhaust velocity?
Is the laundry room humid than traditional? Does the dryer want extra garments drying time to dry out the same amount of garments? Is there a burning smell coming from your dryer? Is there lint current in areas across the dryer or inside the drum?
