Why are my clothes not drying?

Crowley electric dryer is not drying my clothes. I completely changed the exhaust vent. I cleaned the lint trap. I see no clogs or build up in the machine. It is heating just fine, when I open the door steam rushes out. I’ve had one load of laundry in the dryer for a week. I run the dryer once or twice a day but am so frustrated I give up easily on it. I’ve taken half of the clothes out and still no luck. Heat is escaping to the outside but it doesn’t seem to be as much as normal.
