ABSTRACT:
A fabric drying apparatus including a fabric tumbler is provided which includes control circuitry for interrupting a cycle upon detection of temperature signals outside a predetermined range. A power supply energizes the fabric drying apparatus. A heater is generally associated with the fabric tumbler for providing heated airflow thereto. Temperature sensing circuitry includes at least one thermostat for controlling the cyclic operation of the heater to provide airflow in a predetermined temperature range. The temperature sensing circuitry further includes oscillator circuitry operable to provide a frequency output variable in response to airflow temperature. A control system includes a microcontroller in communication with the oscillator circuitry, the cycle selection switches, the display system and the power supply. The microcontroller is operable for monitoring the temperature of the airflow through the frequency output of the oscillator circuit and for deenergizing the fabric drying apparatus and preventing reenergization thereof responsive to a frequency output outside a predetermined range. The frequency output outside of the predetermined range is indicative of a failure of the cycling thermostat or the thermistor circuitry and the microcontroller will effect the display of a coded message corresponding thereto in the display system.
