Indicators that your dryer duct needs to be cleaned:
- Clothes (especially towels or jeans) take a long time to dry?
- Dryer running hot?
- Flapper on vent hood doesn’t open when dryer is on?
Experiencing long drying times?
Lint build-up reduces air flow causing dryer to overheat. When this happens, the high temperature limit safety switch has to cycle on and off to control the heater. Most high temperature limit switches were never designed to cycle on and off continuously which can cause them to fail over a period of time.
