First, connect the part to a multimeter in resistance measurement mode to the part and measure the value. Write it down, which you actually already did do.
Next, use a soldering iron on one of the leads to heat up the part. Check if the resistance is changing and if it is, is it going up or down. Next, if you can, put the part in a freezer for a a couple of minutes and measure the resistance. See if it changed and if it did, did it increase or decrease.
I expect the part to be a negative temperature coefficient thermistor. They operate by decreasing their resistance as the temperature increases, so when the unit just turns on, the resistance will be high, limiting the in-rush current which is often caused by charging of input capacitors. After a while, the part will heat up and resistance will decrease. At that point, the capacitors should have be charged and the circuit should be ready for normal operation.
In catalogs, look for phrase NTC Thermistor or just NTC (if that is indeed a thermistor) and you might be lucky and find appropriate component.
On the other hand, it might be a fusible resistor used instead of a real fuse, but I don't think that such resistors in the pictured format would have printed text on them. Instead, ring marks seem to be more common.
I definitely recommend replacing that part, once it's identified.
Also note that there's a pretty high chance that this part isn't the only thing that died. I suspect that its failure was caused by failure of some downstream component.
