There is a six year old LG electric dryer that is in good condition. The average lifespan of an electric dryer is about 14 years, but they can last up to 18 years.
As mentioned elsewhere, the vent ducts for the dryer are a bit clogged with lint and should be cleaned as part of regular maintenance. This will help the unit run efficiently and extend its lifespan. It also reduce the fire risk posed by excessive lint buildup.
