    Cooler flow switch failure if it is the thermal-dispersion flow switch showing failure then the board isn't getting a signal back from it. You need to know what the actual pressure drop is across the cooler and be able to monitor it before saying that the switch is bad. Small mice have been known to eat the wires sometimes.
