5. DOE Clothes Dryer Sensor Research
 DOE is conducting research to characterize the capabilities and
design of current automatic termination sensor technologies and
control strategies.
• Test units: 4 vented electric standard, 2 vented electric compact, and 2
vented gas dryers.
• Testing to evaluate control signals during the cycle, accuracy of
sensors/controls to detect different conditions (e.g., RMC levels), other
design limitations.

6. DOE Clothes Dryer Sensor Research
 Investigate options for improving the accuracy of automatic
termination sensing, including:
• Potential design changes that can be implemented with current sensor
technologies (e.g., changing sensor location, adding additional sensors,
modified control strategy, etc.).
• Alternative sensor technologies and control designs to significantly
improve the accuracy of automatic termination sensing.
 Conduct testing to evaluate the effects of these design changes on the
accuracy of the automatic termination controls.
• Using existing and modified sensors and controls.
• Using appendix D1 and D2 test methods with the current DOE, AHAM
HLD-1-2009, and AHAM HLD-1-1992 test loads.
• Evaluation of the over-drying energy consumption when drying different
loads below consumer-accepted RMC levels.
