Had to replace dryer heater coil. At the same time, I changed out all the fuses that were involved in the heating process. Cleaned out all the lint that had collected in the bottom of the dryer over the past 5 years or so and there was a lot of lint.Replaced dryer vent to the outside of the house as the old vent was metal and had lots of stuck on lint inside it. Was easier to replace than to clean. The personnel at Appliance Parts Pros were a great help in completing this process.
