Amana Washer NFW7200TW Machine does not work properly in ATC mode.  Ran 'quick service cycle' and both hot and cold solenoids responded in 5 second test.  Will work in Hot/hot or cold/cold, but not in automatic temp control - only cold flows.  Water temp thermistor?  How verify?  Ohm test or any circuit board test mode?  No error codes so far.  Thanks, Jeff (20 year HVAC tech experience & have multi-meter)

Have you performed circuit board test? We have seen this issue with this model washer and was faulty circuit board. How old is washer?

I will do the circuit board test and check for the 2.5 VDC between 3 & 6 on plug #3. Hope it is not the circuit board since I gather that they are obsolete. Any work-around? the machine is only 4 years old.

Not sure of a work around. Would need to replace circuit board if the VDC is not correct.

Measured between pins 3 & 6 on CL3 and had static 5 VDC. Also connected plug and measured 3.126 VDC through the connection. Ran board input and output test and had no issues. Only problem is ATC……….does that condemn my board? If it is obsolete, is there a replacement board available?
