Thermocoupler Daughter Board Fault Light
My thermocoupler connection on the daughter board is not working, and I'm getting is the 2000c error reading. In addition the "fault" light is lit on the daughter board. I could not find any documentation on the "fault" light. can someone tell me what it means. I also unconnected all wires to the daughter board turn on the main board and the daughter board fault light remains "on" with no wires connected. I reset the main board a number of time and re-seated the daughter board but the fault light on the daughter board will not go out. suggestion???
The fault led will illuminate if the thermocouple is not connected or it is shorted to something else.
