Just a reminder about something we all know about and yet most of us ignore until we have to address it.
Yesterday my wife was complaining to me about the dryer not working very well, requireing things to be cycled multiple times, etc.
Yep you guessed it, the vent line was almost completely clogged w/ lint.
To make a long story short, I trashed all the old line and redid it to make a shorter, cleaner run. Also a happier spouse.
If it's been a while since you hooked up your dryer, it may be worth your while to disconnect the vent line and have a peek.
