Duct BlasterÂ®. 1  A Duct Blaster is used to directly pressure test the duct system for air leaks, much the same way a plumber pressure tests water pipes for leaks. 2  The Duct Blaster fan is first connected to the duct system at the air handler cabinet, or a return grille. After temporarily sealing all remaining registers and grills, the Duct Blaster fan is turned on to force air through all.
Turn the dryer on, and check the air flow from the dryer by examining the outdoor duct opening. If the air flow is reduced, remove and clean the exhaust tubing. The tubing should be cleaned regularly to prevent overheating. The cycling thermostat is located inside the dryer, near the heating element. If the cycling thermostat is not working properly, the heating element can overheat. To test the cycling thermostat, remove the connections between the thermostat and the heating element, and use a multimeter to test the cycling thermostat.
