If you have a multimeter, you can test to see if your ice dispensing switch is good or not.

Set your multimeter to the continuity function with beeper.

Touch one probe to each of the switch terminals at the same time.

Use your finger to press the operating lever connected to the switch; the meter should sound and read 1Ω or less.

Release the lever, and the meter should not sound and should read OL for open loop.

If the switch does not operate as described in the steps above, follow the next steps to replace it.
