Cooling fan diagnosis GE JVM1443WK

Question

I think my cooling fan inside the oven failed.
I can not find any info on it to test to see if it is any good. Has three terminals on it. One has a single black wire, the other has a black wire and orange wire, and the third has a white wire and a pink wire to it.
Not getting continuity from the terminal with the single black wire to either of the other two terminals, but am getting continuity between those two terminals
