The feedwater pump
will not run in auto or flush mode. There is 13.58 volts getting to the red wire (position 3 in the schematic) of the speed board but zero volts going to the motor
Likewise, when I flip the switch to Service
, the feedwater pump
does not run.
The feedwater pump works as expected when I flip the switch to manual run mode.
I've checked continuity of the wires between the connect board and the speed board and they all are good.
Also, when the unit is sitting idle, I'm still seeing 6.7 volts on the red wire on the speed board.
This leads me to believe, I've got a bad control board but I'm not sure.
