Abstract
A control system for a clothes dryer has an inlet thermister located in the air flow system prior to the dryer drum to monitor the inlet temperature. This inlet temperature signal is provided to a microprocessor which samples this temperature over time and when this temperature exceeds a predetermined rate of increase with respect to time, the microprocessor generates an air flow restriction or blockage signal representing an air flow restriction or blockage in the dryer vent ducting.
