Hydraulic Cooling Fan Sensor
I think I may have a hydraulic cooling fan sensor going bad. I do
not have a drawing but the book says the fan is to operate from 400- 800 RPM normally and 1800 RPM in fan override. My fan is operating but I do not see the temp guage cycle as before indicating increased and decreased air flow. My temp guage has always cycled between 180 and 200 when not in fan override. I am also seeing creaping heat up to 210 until I put the fan in fan override. I can hold the water temp at thermostat value in fan override. Does anyone know the temperature range of the fan sensor and the fan RPM while in normal operation. There was a prior post addressing an overtemp problem referring to some washers, but nothing about normal variable fan speed ops. After he changed the washers his guage cycled as does mine. I called BB and found Bennie Collier has been transferred to the school division. That can't be good, and I did not find anyone else who knew the answer.
