Mate - once again test out of circuit to be 100% sure - just lift one leg of the resistor though - no need to pull the whole thing out. Problem with testing anything in circuit is that the voltage you put across it with your DMM will take the path of least resistance and if there is a circuit to go around that is 2.1K and not 2.7K then it will take the lazy path ... electricity is a bit like teenagers really when you think about it
