I have an Indiglo IY0450 ice machine that is making ice but will eventually go into safe mode. I am getting E08 TXV faults with every cycle...to the tune of about 80 faults per day. After going into the freeze cycle the difference between T3 and T4 is 37F. I believe it should be less than 12F at 5 minutes after the freeze cycle start. T3 temperature never goes below 53F while T4 gets down to 10F. I have thoroughly cleaned the machine, replaced T3 thermistor and it is still doing the same thing. Not sure what to do next.
