- 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. Both damaged wire ends showed green oxidation on the copper wires, suggesting protracted time for the damage to occur. (I previously replaced these wires with large (10Ga vice OEM 14Ga) wires, and Hi-Temp connectors, for the same reason, about 5 years ago.)
- Checked continuity across 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 good (Open)
- Checked for continuity between motor plug (that had the previously melted, Black wire leading into it from the heater) and found continuity from the heater input plug and one of the 120V leads on the wall plug. (the Black wire was disconnected for the test) I think this should be an Open when the motor is not running
- Does this indicate I have a bad motor switch and need to replace the motor?
Thank you for any insight you might have.
