Run a Dryer Vent Blockage Test
The Vent Blockage test automatically detects the status of the exhaust ducts and reports any blockage or problems. This is great because proper ducting can reduce drying time and save energy.
Not all dryer models have a Vent Blockage test. To confirm if your model has a Vent Blockage test, and the steps to perform it, view the user's manual for your model.
