Disconnect and restore power. The reading should be okay unless you have a bad thermistor amplifier or bad connector/connection at the board
Did that, readings were still off .
Check the thermistor amplifier by doing a dc voltage check at the ff thermistor while the connector is attached to the board.
I will do that! I am going out armed with a new board and thermister. I checked the thermister charts and the readings look as if the values are correct... Hmmmm.
Thank you again!!
