Brivis Classic Electronic Control Board

This Brivis Classic Electronic Control Board (PCB) is the brains for older Brivis ducted gas heaters. It's crucial for getting your heater running right, especially when troubleshooting erratic operation or a complete no-start.

Swapping out a faulty board can often revive a system that’s otherwise solid, saving the customer from a full unit replacement. It's a common replacement part after years of Australian summer heat cycling, which can take its toll on electronic components.

Best For

• HVAC service technicians
• Gas heater repair specialists
• Homeowners maintaining Brivis Classic ducted gas heaters

Compatibility

This control board is specifically designed as a direct replacement for Brivis Classic ducted gas heaters. It replaces existing boards marked with part numbers HCCA621, B021169, or Brivis PN: 80021169. If you're running a different model, check fittings and specs before ordering.

Features

• Direct replacement for Brivis Classic gas heating systems.
• Manages ignition sequence, combustion fan, and other critical heater functions.
• Identical to Brivis part numbers HCCA621, B021169, and 80021169.
• Essential component for restoring reliable heater operation.

What's in the Box

• One Brivis Classic Electronic Control Board (HCCA621)

Using It on the Job

1. Always isolate main power to the Brivis heater at the circuit breaker and ensure it's locked out before opening any panels.
2. Carefully open the heater's control compartment and photograph existing wiring connections for reference.
3. Disconnect all low voltage and high voltage wiring from the old PCB, noting their positions.
4. Unmount the old control board and install the new BS-HCCA621 board, ensuring all mounting points are secure.
5. Reconnect all wiring exactly as photographed, double-checking each connection for correct polarity and tightness.
6. Restore power and perform operational checks to confirm the heater is cycling correctly through ignition, heat, and fan stages.

Limitations & Safety Notes

• Only for use with compatible Brivis Classic ducted gas heating systems.
• Electrical work on gas appliances should only be performed by qualified personnel.
• Always isolate power before commencing any work on the appliance.
• Follow Australian standards and Safe Work guidance for gas appliance servicing and maintenance.

Tradie Pro Tip

Before you swap out the board, always double-check the simpler stuff first. Ignition leads, flame sensors, pressure switches – they can cause similar symptoms to a bad PCB, and they're a much cheaper fix if that's all it is.

Pair With

A good digital multimeter and a set of temperature probes are essential for diagnosing gas heater faults. You might also find a gas pressure manometer useful when servicing the whole system.
