Coolbreeze QA/M Maxima Control Board

Using It on the Job

1. Isolate Power: Always ensure the main power to the evaporative cooler is completely switched off and locked out before opening any panels or beginning work.
2. Access Board: Carefully remove the old control board, noting all wiring connections, plug positions, and mounting points. Taking a photo can save you grief later.
3. Install New Board: Mount the new CBSP3011 board securely in place. Reconnect all wiring harnesses and plugs, ensuring they are firm and correctly seated.
4. Verify Connections: Double-check all wiring against your reference photos or the unit's wiring diagram to ensure nothing is missed or incorrectly connected.
5. Test Functionality: Restore power to the unit and test all functions of the evaporative cooler, including fan speeds, pump operation, and any auxiliary modes.

Limitations & Safety Notes

• This board is specifically for Coolbreeze QA/M Maxima and Neatrol Roof Units; it may not be compatible with other models.
• Electrical work should only be performed by appropriately qualified and licenced individuals.
• Always ensure power is isolated and locked out before attempting any repairs or replacements.
• Follow all Australian standards and Safe Work guidance when servicing electrical appliances.

Tradie Pro Tip

Before you even pull the old board, check the wiring harness for any signs of corrosion or burnt connections. Sometimes the issue isn't the board itself, but a failing connection that needs cleaning or replacing.

Pair With

Consider checking out other Coolbreeze spares like replacement pumps, float valves, or wall controllers when you're servicing the unit. Having these on hand can reduce call-backs and speed up future repairs.
