9. Now set your ohmmeter to its greatest resistance scale and touch one meter result in the NO terminal and the other meter cause the NC terminal.

10. The resistance reading in between these two leads must be infinite.

11. Lastly take a resistance reading from both the NC terminal and the NO terminal to any metal mounting hardware that belongs of the switch assembly. You must get a typical reading of infinity.

Any readings that vary from the tests above are signs of a defective door switch that will need to be replaced.
