Clothes dryers are inspected for several factors, with most emphasis on the dryer exhaust system. The system is connected to the clothes dryer vent outlet that exhausts air from the dryer blower to a designated area. Remove combustion gases (including carbon monoxide), heated air, moisture, and lint from the dryer to a designated area.
- Improvised filter materials (e.g., stockings, t-shirts, etc.) attached to the duct line are considered a blockage and should be recorded as a deficiency.
- Look at the exhaust ventilation system and identify the flexible duct line and the entire duct line that runs from the back of the dryer.
- Look for crushed pipe or any unintentional kinks in the duct line.

We were cited for 3 tenant clothes dryers for exposed electrical wiring. Their cord cover was missing. We did inspect dryer vents and transition duct materials but did not inspect for other dryer components. Is this appealable?
