Brivis Evaporative Cooler Fault Codes:

Code	Fault Description
“Dead”	No Power – There’s an 8A ceramic slow-blow 3AG fuse inside the control module.  Turn off and disconnect the mains power from the cooler, remove the control module and carefully open it, then check the fuse using a multimeter set to continuity or ohms measurement mode to confirm that the fuse has not blown.  If the fuse has blown, the most likely cause is a faulty fan motor.
Overflowing	If the cooler is overflowing or the water inlet solenoid valve will not turn off, the most likely causes are a faulty water sensor or faulty control module (unable to sense water at high level).
ServoSeal not operational	Both the ServoSeal assembly and the control module can be the cause of this problem.  You may find that the ServoSeal is stuck in one position (open or closed) or that it is vibrating.  If the ServoSeal arm is gently vibrating, this is a sign of a control module fault.
30	FAN_LIMP – The fan may not be running, not running at the correct speed or there may be no signal coming from the fan speed sensor.  The speed sensor is located on the back of the fan motor.  It may stop working if it becomes detached from the motor or if dirt/dust builds up inside the sensor.
40	The low level water sensing has failed.  This can be due to a faulty water sensor or a control module fault.  Test the water sensor by checking for continuity between each water sensing plate and a wire in the plug and try cleaning the water sensor (brush and soapy water, rinse thoroughly afterwards).
41	The high level water sensing has failed.  This can be due to a faulty water sensor or a control module fault.  Test the water sensor by checking for continuity between each water sensing plate and a wire in the plug and try cleaning the water sensor (brush and soapy water, rinse thoroughly afterwards).
42	The water is unable to be drained from the cooler.  This could be due to a blocked drain or inoperative ServoSeal.  The control module may also be faulty, causing it to be unable to operate the ServoSeal.  If the cooler has drained, try cleaning the water sensor, as a dirty sensor could cause the control module to think that water is still present when it isn’t.
50	Unable to detect water.  After opening the solenoid valve to allow water into the cooler, there was no water detected after 15 minutes.  Check that the water supply to the cooler is on and that power is getting to the solenoid valve when the cooler is turned on and in cool mode.  Check that water isn’t draining from the cooler (this may be due to a faulty ServoSeal or faulty control module).  If the cooler is filling with water or overflowing, the water sensor may be faulty or the control module may have a fault in the water sensing circuitry.
60	MOTOR_OC – The fan motor is open-circuit.  This can occur if the fan motor has overheated and the internal thermal protection has been triggered.  If the fan motor is not open-circuit, then it is likely to be a faulty control module.

LED Flashes	Fault Description
4	Water not detected at high level.  The water sensor has detected water at the low level, but has not detected water at the high level.  Check that each of the plates of the water sensor have continuity to one of the wires in the plug at the end of the water sensor cable.  If the water sensor is found to have continuity and the cooler is overflowing with water, then the water sensing circuitry in the control module has likely failed.
6	Water not detected at low level.  The cooler has energised the water inlet solenoid valve but water has not been detected by the water sensor at the low level (timeout is approx. 10 minutes).  This may be caused by a faulty damper, causing all water to drain out of the cooler as it tries to fill.  The damper assembly may also be vibrating, due to a control module fault, which will cause it to get stuck in either the open or closed position.  This fault can also be caused by a faulty solenoid valve (burnt out or seized in the closed position), faulty water sensor or faulty water sensing circuitry in the control module. Check that each of the plates of the water sensor have continuity to one of the wires in the plug at the end of the water sensor cable.  If the water sensor is found to have continuity and the cooler is overflowing with water, then the water sensing circuitry in the control module has likely failed.  The cooler may also run the fan and blow hot air when this failure occurs.
7	Fan Motor Open Circuit.  The fan motor is open circuit, most likely due to the fan motor overheating and tripping the thermal protection mechanism inside the motor.  This may be due to a degraded fan motor run capacitor (check capacitance), or a short circuit inside the fan motor.
