Kenmore Elite 796.29002000 Water temp

[Capon]

Kenmore Elite, 796.29002000, doesn't fill with warm/hot water as selected. All hoses have been clear of foreign matter. Screens have been cleaned, Solenoids (both hot & cold) measure about 29 ohms resistance (no opens or shorts).
When selected to "whites", program preselects to hot (wash)/cold (rinse). After tub fills to determined level the temp is somewhat cold (approx 81°F). I even tried another load selecting "heavy duty" and "stain boost" trying to increase water temp, but obtained about 91°F. 
The service manual (pg 10) states hot should be approx 120°, warm approx 90° and cold approx 66°.
The measured hot water supplied is approx 135° (hot H2O tank is about 10 ft away).
During fill, the hot water flows and sometimes shuts off after 30-45 sec or so.
No error codes and I performed the QC test. seemed fine.
I'm now wondering if the thermistor, which I understand monitors water temp, is deteriorating and sending incorrect data to the main control board which in turn controls the hot/cold supply via energizing the respective solenoids on the inlet valve assy. Everything else works fine. 
FYI...the main control board was replaced last year (no power, no lights, no nothing)

Any thoughts? Can thermistors have an effect on water temp?

Hi Capon, yes In GENERAL the thermistor, if equipped can cause temp variation off design.  Is there a tech sheet inside the washer?  If so please post a pic of the wiring diagram.

Perchance, are the supply hoses reversed?
