Breezair speed control for evaporative coolers.<\/figcaption><\/figure>\n\n\n\n Breezair fault codes can also be displayed and read from the front display LED of the Breezair speed controller. This is shown by the blinking red Diagnostic LED this is called DIAG on the speed controller. <\/p>\n\n\n\n
When the evaporative cooler fan is operating normally, the DIAG LED on the front of the speed controller is green and will flash quickly twice. With a small delay between the fashes. This is good.<\/p>\n\n\n\n
If a fault is triggered on the speed controller the DIAG LED will turn red and flash a fault code. This flash code sequence is the fault code number. A single red Diag LED blink would indicate fault code 1, two quick red blinking LEDs would indicate fault code 2, three quick red blinking Diag LEDs indicate fault code 3, four red blinking LED lights would indicate fault code 4, and so forth. Reset the fault code by turning off the unit and back on again once the fault has been rectified. The DIAG LED can change from green to red and back again, but the SAL LED is always red in color. It will either be flashing or constantly on this is normal depending on the water level.<\/p>\n\n\n\n
Breezair Fault Code 1<\/h3>\n\n\n\n Error Code 1 Indicates a communications problem with the remote control. Check the data cable between the wall remote control and the evaporative swamp cooler for damage and continuity. Check the wireless remote that the batteries are good.<\/p>\n\n\n\n
Breezair Evaporative Cooler Service Code 2 Fault<\/h3>\n\n\n\nAn Error Code 2 means that there is no water at the sump covering the salinity probes. <\/p>\n\n\n\n
Fix: The mains water supply to the cooler could be turned off, the solenoid valve may be stuck closed, the dump valve may be open and not be closed, the salinity probes may be dirty\/faulty, or the speed controller salinity sensing circuit may be faulty.<\/p>\n\n\n\n
Breezair Fault Code 3<\/h3>\n\n\n\nAn error code 3 that there is a problem with internal EEPROM memory chip corruption or failure. The speed controller will store a small amount of code data to help the unit run and remember settings. This has default settings for the operation of the evaporative cooler. Replace the speed controller this is not a DIY replaceable part.<\/p>\n\n\n\n
Breezair Evaporative Cooler Service Code 4 Fault<\/h3>\n\n\n\nAn error code 4 means that the evaporative swamp cooler is not able to drain the water from the reservoir sump quickly enough. You will get a fault error code after around 4-5 minutes of the water being in contact with the salinity probes. The Breezair will go into fault condition if water is still detected by the salinity probes. Possible causes could be a problem with the drain valve such as a material blockage, scale, failed drain valve motor, or limit switch fault. Excess foam can also cause this problem.<\/p>\n\n\n\n
Fix and replace the dump valve if not reach the limit and or clear the blockage. <\/p>\n\n\n\n
Breezair Fault Code 7<\/h3>\n\n\n\n An error code 7 is a 50Hz frequency fault. This is due to the fact that the mains power supply frequency is not normal. Australia has a standard 50Hz power supply frequency that is constant and should not drift. <\/p>\n\n\n\n
If the frequency drifts too much such say between 45-55Hz a fault code will pop up. This is rare and I have yet to see this fault. It is designed to protect the speed controller and motor.<\/p>\n\n\n\n
Cause: This can be caused by corrosion inside the speed controller eg rust, corrosion, moisture, bugs, dirt, or failed electrical capacitors. Portable generators that drift can have a bad frequency that can damage sensitive electrical devices.<\/p>\n\n\n\n
I have seen old tornado water pumps cause electrical arching which can cause this trip. Replace the water pump. Welding near the evaporative cooler can also cause this error.<\/p>\n\n\n\n
Breezair\/Breamer Fault Code 8<\/h3>\n\n\n\nAn error code 8 means that a power failure has been detected such as a blackout\/brownout. Turn the unit on and of to reset.<\/p>\n\n\n\n
How to reset Breezair evaporative cooler<\/h2>\n\n\n\n To reset a fault code on a Breezair evaporative cooler you need to turn off the mains power to the cooler. Waite at least 2-5 minutes and then turn on the main power.<\/p>\n\n\n\n
The Breezair evaporative swamp cooler will perform some internal self-checks. If the remote is set for cooling the Breezair unit will close the dump valve, fill with water and start the fan. This is a pass. <\/p>\n\n\n\n
Conclusion<\/h2>\n\n\n\n Hopefully, you can fix your Seeley Breezair swamp cooler with the above troubleshooting guides. They are easy to work on but the parts cost a fortune.<\/p>\n\n\n\n
Many of the older units have a lot of problems. The old green motors tend to fail within a few years if run at maximum speed. The internal windings tend to short out. This is a manufacturing fault that should never happen. The white motors are much better.<\/p>\n\n\n\n
I brought my Breezair Icon evaporative cooler to save money but over the years it has cost a small fortune on repairs. I’m just glad I could do it myself.<\/p>\n\n\n\n
This is why I have written out this Breezair evaporative cooler troubleshooting guide so you can save on some labor costs.<\/p>\n\n\n\n
