Ah.. guess it's a polyfuse. Aliyusufee you may need to see if any lettering remains visible on the original part that was there. Otherwise you may need to guess based on knowing what that relay switched…

Think it would help if you drew an arrow pointed at the location you wish people to look at, because we can't guess where your eyes are looking at. The whole board is dusty and dirty, so it's not easy…

Do you mean that blue disk? If so, that's not a thermistor, that's either a varistor (MOV) or a capacitor, I can't tell. Or did you want people to look at a different part of the board?

Good point.. could be that too! If possible, a photo of it would help (even if it's damaged).
