- Dryer stopped heating with motor running, then shortly thereafter the motor stopped but continued to hum. - Opened up unit and found Black wire between heating element and motor input was melted at motor plug--also found other (Purple) wire leaving heating element to cycling thermostat was severely heat damaged at plug on the heater terminal. (I previously replaced same wires with 10Ga vs OEM 14Ga wires/Hi-temp connectors for same reason, about 5 years ago.). - Checked continuity on Hi/Low/ Limiting thermostats at room temp--all good. Also checked them for shut-off at higher temperatures (in an oven), all working properly. - Replaced melted wiring and connectors. Plugged the unit back into the wall and immediately detected heater element becoming hot, even though it had not been turned on at the control panel. Immediately disconnected the dryer from the wall plug. - Checked for ground between heating element and ground and neutral--both tested Open. - Checked for continuity between motor plug (that had the previously melted, Black wire from the heater) and found continuity from the heater input plug and one of the 120V leads on the wall plug. I think this should be an Open when the motor is not running. - Does this indicate a bad motor switch?
