Hi Hercules,

Yes possible the power line could have a high current surge.

Hi Mark,
If ntc is very hot then there could be something has shorted. Have you checked if the output voltages from the power supply low or pulsate? You may have to isolate it by going into this link below:

Hi KLR,

Probably the thermistor is already in bad condition otherwise it would not spark. Most of the time it will have very tiny hole in the thermistor body.

Hi KLR,

Sorry i can't provide to you this info becase I'm not into designing field. I suggest that you visit those electronics design forum as I believe there will be someone in the forum that can assist you on this matter.

It the component is connected in series with the main ac line the it is a thermister. If it is connected parallel between the main ac line with the ground then it is a varistor.
