Breezair, Braemar & Coolair Fault Codes: 01, 02, 04, 07 and 08 Explained
Nov
When a Breezair, Braemar or Coolair evaporative cooler finds a problem it stops, flashes SERVICE on the wall control and shows a fault code number. The same codes are flashed in red on the electronics module inside the cooler’s control box. This guide explains what each Breezair fault code means, what usually causes it and which part to check, so you can sort out simple problems yourself or order the right part before the technician arrives.
How to read the fault code
- When SERVICE flashes, turn the wall control off.
- Write down the number flashing at the bottom of the screen (for example 02 or 04).
- Turn the cooler back on. If SERVICE comes back with the same number, the fault is real and needs fixing.
On the electronics module the code is shown as red LED flashes: 2 red flashes = code 02, 4 red flashes = code 04, and so on. Two green flashes is normal operation. Older CPMD-controlled coolers (EXH, LCB, CPL and similar) show the same faults with an “FC” prefix, such as FC2 or FC04.
Breezair, Braemar and Coolair fault code table
| Code | What it means | Most common causes | Parts to check |
|---|---|---|---|
| 01 (1 red flash) | Communication failure between the wall control and the cooler | Wall control cable not plugged in properly, damaged cable in the roof space, faulty wall control | 4 pin CPMD cable, 6 pin MagIQtouch cable, wall controllers |
| 02 (2 red flashes) | No water detected at the probes within 20 minutes of filling | Water tap off, inlet solenoid not opening, blocked inlet strainer, water pressure below 100 kPa, drain valve not closing, probe plug loose or upside down | 24VAC solenoid valve 834320, 12VDC solenoid valve 865607, water sensor probe 833811, drain valves |
| 04 (4 red flashes) | Water still detected at the probes 20 minutes after draining started | Drain valve not opening, blocked or kinked drain hose, inlet solenoid not shutting off (or fitted backwards), dirt on the probes, cooler not level | 24VAC drain valve 105345, 12VDC drain valve 116389, solenoid valve, sensor probe |
| 07 (7 red flashes) | Motor error | Motor power or communication cable loose at the control box, failed inverter board inside the motor | Motor cables and plugs first, then the fan motor (the inverter board is not sold separately) |
| 08 (8 red flashes) | Supply voltage error | Mains voltage dropped below about 93V. The fan stops and restarts on its own once voltage returns | No cooler part. Check the circuit, breaker and power supply to the cooler |
Code 02: no water (the most common fault)
Code 02 means the cooler opened its inlet valve but the water sensor probes did not detect water within 20 minutes. Before buying parts, check that the tap to the cooler is fully on and that water hasn’t been cut off in your street. Then check the following:
- Solenoid valve. With the cooler calling for water, the solenoid should click open and water should flow. No flow with power at the valve usually means a failed solenoid. Most Breezair, Braemar and Coolair coolers use the 24VAC 834320 solenoid; Super Stealth XTR and some 12V models use the 12VDC 865607.
- Inlet strainer. A small filter at the solenoid inlet blocks up in hard-water areas and starves the cooler.
- Water pressure. Seeley coolers need roughly 100 to 800 kPa at the inlet. Non-return isolation valves in the supply line can also lock up; a ball valve is better.
- Drain valve. If the drain valve doesn’t close fully, the tank empties as fast as it fills.
- Probes. A loose probe plug, a plug fitted upside down, or a coated sensor probe stops the cooler seeing the water.
Code 04: won’t drain
Code 04 is the opposite problem: the cooler opened its drain but still senses water 20 minutes later. Start with the drain hose (blockages, kinks, long runs with lots of bends that air-lock). If the hose is clear, check whether the drain valve actually opens. Coolers with CPMD or MagIQtouch controls use the 24VAC drain valve 105345; 12V models use the 12VDC drain valve 116389. Also check that the inlet solenoid shuts off during the drain. A solenoid fitted against its flow arrow can let water through and keep the tank topped up.
Code 07: motor error
On inverter-driven coolers (Icon, EXQ, EZQ, LCQ, CPQ and similar) the motor has its own control board. Code 07 means the control box lost contact with the motor or the motor reported a fault. Switch off at the isolator, check both motor plugs at the control box are fully seated and undamaged, then restart. If the code returns with good cables, the motor assembly usually needs replacing because the inverter board is built into the motor. Our evaporative cooler motor guide explains which motor suits which model.
Code 01: communication failure
A 01 code usually comes from the cable between the wall control and the cooler. Check both plugs, and look for damage where the cable runs through the roof space. CPMD controls use a 4 pin cable and MagIQtouch controls use a 6 pin cable, so make sure you replace like with like. If a new cable doesn’t fix it, the wall control or control box may be faulty. See the Breezair controller guide for matching controllers and control boxes.
Frequently asked questions
Can I just reset the fault code?
Turning the wall control off and on clears the code, but it will come back if the cause is still there. A code that returns with the same number points to a real fault.
Does code 02 mean the pump has failed?
No. Code 02 is about filling the tank, not pumping water to the pads. A failed pump usually shows up as warm air with dry pads and no fault code. Our pump guide covers pump faults.
Who should do the repair?
Checking taps, hoses and plugs is fine for most owners. Anything inside the control box or involving mains power must be done by a licensed electrician or qualified technician.
