Got the evap cover in yesterday and installed. The unit had thermistor fan and pantry diverter as well as an upgraded gasket and pad that rests against the evap.
everything has checked out fine this morning!!!!!!
i suppose the main board replacement coupled with the evap/thermistor replacement did the trick.
of notwhen going through this I found
1. Condenser air inlet blocked with dust/dirt
2. Main board at rev 4.0.0. (Needed 6.0.0)
3. Evap froze solid
4. Evap thermistor located a bit up the tube ( lowered on reinstall)
