We were recently given a Kenmore Coldspot Model # 70192000 Serial # EK0815247 Manufactured 2-00. I had to purchase from Home Depot the 1/4 water line with filter to hookup the automatic ice maker. After connecting the ice maker to the water line and turning on the water, the water does not flow out of the pressure regulator. I have opened the valve all the way and still can not get water to the ice maker. Could the regulator need replacing or are there missing parts? I appreciate any help

How did you connect the ice maker line to the main line.

I connected the ice maker to the water line to our second sink. I used a self peircing saddle valve that was included with the 1/4 tubing and filter.
