Common Brivis Heater Issues and How to Troubleshoot Them

Brivis gas ducted heating systems are known for their reliability and energy efficiency. But like any appliance, they can develop faults over time. At Airmax, we regularly help Sydney homeowners resolve common Brivis heater issues—many of which can be easily identified and sometimes even resolved without the need for a full service.

Below are the most common Brivis heater problems we encounter, along with basic troubleshooting tips you can try before calling a technician.

1. Brivis Ducted Heating Not Turning On

If your Brivis heater is completely unresponsive, the issue could be electrical or controller-related.

Possible Causes:

• Tripped circuit breaker
• Faulty thermostat or wall controller
• System lockout due to an error
• Disconnected or loose wiring
• Dead batteries in older controllers

What You Can Do:

• Check your Brivis controller display to see if it’s on and set to the correct mode (e.g., “HEAT”).
• Reset the unit at the switchboard or via the Brivis reset button.
• Make sure there’s power supply to the unit.
• Replace the controller batteries if your system uses a battery-powered model.
• Still not turning on? Contact Airmax for a full system inspection and electrical diagnosis.

2. Brivis Ducted Heating Blowing Cold Air

If your vents are pushing out cold air instead of heat, it typically means the heating function isn’t igniting or cycling properly.

Possible Causes:

• Pilot light is off
• Faulty gas valve or ignitor
• Incorrect thermostat setting
• Dirty flame sensor or burner

What You Can Do:

• Check and relight the pilot light (refer to your Brivis model manual).
• Verify that the system is set to “HEAT” mode and not “FAN” or “AUTO.”
• Perform a system reset (see instructions below).
• Clean or check your air filters and vents for blockages.

If it continues to blow cold, it may need professional repair—especially if gas or ignition components are involved.

3. System Keeps Turning On and Off (Short Cycling)

Short cycling can overwork your system and increase energy bills.

Possible Causes:

• Overheating due to blocked vents or dirty filters
• Faulty thermostat
• Incorrect temperature calibration
• Sensor or controller issues

What You Can Do:

• Clean or replace air filters.
• Check for any visible error codes.
• Make sure the return and supply air vents are open and unobstructed.
• Reset the system.

Persistent cycling could indicate a more serious issue with sensors or internal electronics. Our technicians can investigate further.

4. Weak or Uneven Airflow

Is one room warm and another cold? Uneven airflow could point to zoning issues or ductwork problems.

Possible Causes:

• Zoning control module not functioning
• Blocked or damaged ducts
• Fan motor running at reduced speed
• Dirty filters or clogged grilles

What You Can Do:

• Check your zoning settings on the controller.
• Inspect all vents for airflow.
• Clean grilles and filters.
• Make sure nothing is blocking the return air intake.

If airflow remains poor, a technician should inspect your fan, ducts, and zone dampers.

5. Brivis Cooling Not Working (If You Have a Dual System)

If your Brivis Climate System includes cooling, but it’s not working, it could be a mode switch or communication issue.

Possible Causes:

• The system is stuck in heating mode
• The cooling module is not responding
• Communication fault between the heating and cooling units

What You Can Do:

• Ensure the controller is set to “COOL” mode.
• Try resetting the entire system at the switchboard.
• Check if any error codes are displayed.

If your Brivis cooling still won’t turn on, Airmax can check module connectivity and controller functionality.

6. Brivis Controller Not Responding

Your controller is your system’s command centre—if it’s not working, the whole system could appear faulty.

Possible Causes:

• Controller firmware glitch
• Flat batteries (older models)
• Wiring issues or controller failure

What You Can Do:

• Try a Brivis controller reset (remove it from the wall, wait 60 seconds, and reattach).
• Replace the batteries (if applicable).
• Power cycle the system at the switchboard.

Still unresponsive? Airmax can test your controller and install a new one if required.

7. ⚠️ Brivis Error Codes or Flashing Lights

Your system may display error codes like 50, 54, E1, E2, etc., depending on the fault and model.

What You Can Do:

• Refer to the displayed error code and check our Brivis Fault Code Guide
• Try a full system reset.

Take note of the error before calling us—it helps speed up the repair.

Brivis Controller Not Working? Here’s What to Do

Let’s walk through the most common controller problems and how to troubleshoot them before considering a replacement.

Common Brivis Controller Problems:

• Blank screen
• Buttons not responding
• The system is not responding to commands
• Zoning not functioning

Troubleshooting Brivis Controller:

• If you see a Brivis controller blank screen, the unit may need new batteries or a hard reset.
• Perform a Brivis controller reset by:
  1. Removing the controller from the wall mount (if applicable).
  2. Turning off the power at the switchboard.
  3. Waiting 1 minute and powering it back on.
• Ensure the controller is paired correctly with the system.
• If zoning isn’t working, check for any error messages or refer to the Brivis zones not working section in your Brivis climate systems manual.

If the issue persists, controller replacement might be necessary. At Airmax, we can assist with Brivis controller replacement or repairs.

Common Brivis Heater Error Codes & What They Mean

Brivis systems display error codes when something is wrong. Here’s what some of the most common Brivis heater fault codes mean:

Error Code 50 – Gas Ignition Fault or Flame Sensor Issue

This is one of the most frequent Brivis error codes, especially in Brivis Buffalo models. It means the system failed to ignite or the flame sensor did not detect a flame.

Possible Causes:

• Faulty ignitor
• Dirty or malfunctioning flame sensor
• Interrupted gas supply

What to Do:
Turn off your unit and perform a reset (see reset instructions below). If the issue persists, contact Airmax to inspect the ignition system and flame sensor.

Error Code 54 – Gas Valve Malfunction or Fan Failure

This code indicates a failure in the gas valve, which may not be opening properly, or the fan, which may not be running as expected.

Possible Causes:

• Blocked or failed fan motor
• Malfunctioning gas valve
• Faulty wiring or control board

What to Do:
Reset the unit. If the code returns, it’s best to have a licensed Airmax technician perform a full system diagnostic.

Error Code 55 – Return Air Sensor Fault

This error means the system can’t detect the return air temperature properly.

Possible Causes:

• Loose or damaged return air sensor
• Sensor disconnection
• Control board error

What to Do:
Power down and reset the system. If the error remains, Airmax can inspect and replace the faulty sensor.

Error Code 56 – Over-Temperature Detected

Your system has overheated and entered protective shutdown mode.

Possible Causes:

• Blocked filters or vents
• Faulty fan or circulation issues
• Defective temperature sensor

What to Do:
Turn off the system, check and clean filters, and reset the unit. If overheating continues, professional servicing is essential to avoid long-term damage.

Are E-Codes the Same as Fault Codes Like 50, 54, 55?

No, they are different:

• Fault Codes (50, 54, 55…) appear during internal diagnostics and are often viewable on the main Brivis unit.
• E-Codes (E1, E2, etc.) are displayed on your wall controller and relate to user-facing issues, such as zoning, sensors, or communication.

In simple terms:

• Fault Codes = Unit-level technical problems
• E-Codes = User/controller-level warnings or faults

💡 What Should You Do if You See an E-Code?

If you’re seeing E1, E2, E3, or similar on your Brivis wall controller:

1. Try a soft reset at the controller or switchboard.
2. Check the filters and vents to make sure airflow isn’t blocked.
3. Call Airmax if the error continues – we can test the return air sensor, fan, zoning module, and controller connections.
