Why would a dryer plug melt?

Answer by  dwmarkel (142)

It would melt because the current going through the wire inside the plug exceeded the capacity of the plug, either because the wire was too small or the current was too great. This caused the wire to heat up due to the resistance within the wire. The heat from the wire caused your plug to melt.

Probably caused by the resistance of the contact point between wire and screw terminal heating up the wire. Wire was probably not stripped correctly or maybe oxidation or sometimes just a loose connection.

Overheating causes the plug to melt. It is because the drier current rating is higher than that of the plug and thus it is overloaded.
