   Check connection of flow meter wiring harness.

2. 2

   Verify water supply to refrigerator is on and supply valve is open.

3. 3

   Check flow sensor resistance: Red wire to Black wire should be 4~30 kOhm.

4. 4

   If resistance is out of range: replace flow sensor.

5. 5

   If harness is loose: reconnect and retest.
