can relay's "blow"? thanks.

 

Relays can go bad and need replacing just like fuses, just not as often.

 

so they would suddenly go out like from too much amperage? reason i'm asking is because my e-fan quit working today and all the wires and connections are good. so besides the fan motor itself being broke i don't know what else it could be?

 

relays are set with a maximum voltage and current that can run through them. Too much and they can blow, or they can go bad from age.

 

Releys develop "pits" over time from making and breaking contact. Eventually that pitting leads to not making good contact and it needs replaced. Hopefully thats your problem because I would imagine the relay is cheaper than the fan motor.
