I have a Noritz N-063S-NG water heater. The CPU board, part number SHA7914, has an issue and the unit is throwing error code 71. Noritz has discontinued the model and the part. Does anyone have the part on hand?
 
I have the exact same problem. i am wondering if there is a substitute board that will work? i read where there was a replacement model for the N-063S. NR71-SV-NG, but I don't know who to ask.
