Abstract

A sensor is installed in the dryer air-stream to verify that an adequate draft is being created by the appliance prior to activating the appliances air-heating system. If the sensor determines that an adequate draft is present, determined, e.g. by a pressure differential in the system, it will allow the appliance's air-heating system (either an electrical element or gas burner) to be activated. If the sensor determines that an inadequate draft is present, this may be symptomatic of a blocked or obstructed air-vent or lint trap, which is a potential hazard. In this case the system will not activate the heating system and an audible and/or visual warning of the failure mode may be displayed.
