Ice make not always making ice

[rreale]

I have a 4 year old whirlpool wrf555sdfz french door refrigerator.  Noticed ice maker not making ice.  I changed the water filter, water pressure increased and I was making ice.  Then noticed the refrigerator was getting too cold (freezing my beers).  Getting to about 25 degrees.   I cleaned the coil and fan underneath (I removed front grill and back cover, vacuumed and blew the dust out).   I am getting ice bucket temperature of 14 degrees.  The bottom freezer is getting a steady temp of -4.  I have the refrigerator temp set to 37 and freezer set to -5.  The refrigerator temperature appears to be stabilizing around 36 degrees.  But getting very little Ice.  I read that I need to be at 10 degrees in the ice bucket to make ice.   I have read about an issue with the ice maker filler tube freezing up.  So I entered diagnostic mode , test 38 (forced defrost) and changed it to "Lo" for long defrost. Also the refrigerator seems to run all the time.  I wake up in the morning and its running after the doors have been shut for 7 hours.

 

Let me know if there is something else to try
