Whirlpool Whirlpool WED5000DW 7.4 cu. ft. Electric Dryer MECH-WONT-START Error Fix: Dryer Will Not Start

Error code MECH-WONT-START on the Whirlpool Whirlpool WED5000DW 7.4 cu. ft. Electric Dryer means: Dryer Will Not Start. The dryer does not start when the Start button is pressed. Check: (1) Door switch — press the button manually and listen for a click. (2) Start switch — does it make contact? (3) Thermal fuse — on Whirlpool dryers, the thermal fuse is on the exhaust duct inside the back panel. If it is blown (no continuity), the dryer will not start at all. The thermal fuse blows due to overheating (restricted vent). Fix the vent issue before replacing the fuse. (4) Drive motor — a failed motor will hum or do nothing. (5) Main control board — verify power reaches the board.
