Thank you for your question.
Without a model number, I will only be able to give you general information.
The dryer needs two things to dry clothes, heat and air flow. If you know the dryer is heating the way it should the problem would be a venting problem. I recommend starting the dryer then checking the vent outside. You should feel blowing out of the vent hood. If you do not feel the air blowing out you have a plugged vent duct. You can clean the vent yourself with a vacuum and a brush or have it done by a vent cleaning company.
If you think, the vent is clear I recommend removing the vent hose from the back of the dryer. Then open any windows in the room and put in a wet load of clothes. Now start a cycle with the vent hose disconnected. If the clothes dry in the normal amount of time, the problem is a restricted vent. The vent has to be cleaned.
If you need further assistance, please reply with the details of what you have found and a complete model number.
