Take off the dryer vent and run the unit to see if it will dry normally. If it does, you still have a blockage in your exhaust vent in the wall.

Most of the time when your dryer is taking longer and longer to dry the clothes it is due to a clogged dryer vent. Just take the vent off and clean it. If the dryer cannot vent it cannot circulate the air inside the dryer

The number one cause of dryer heat related problems is poor exhaust ventilation. If not vented properly, a dryer will not dry efficiently, will actually take longer than required to dry, and will cause the heating circuits to overheat to the point of failure. The dryer will actually seem hotter than usual in many cases as the heating circuits begin to overheat. This is also the source of many fire hazards if not resolved. Read through the link provided and review some of the potential causes.

If you have any questions, please post back and let me know. I hope you find this information is helpful.

NOTE: If you thoroughly check everything and still have problems let me know. The problem could be related to a thermostat failure.
