Braemar Air Conditioner Fault Codes

What does your Braemar fault code mean?

Pick the code showing on your remote, wall controller or indoor unit and see what it means, what commonly causes it, and what is safe to check yourself. This page covers 146 Braemar fault codes for units sold in Australia, compiled from official Australian manufacturer and distributor documentation, the same references our own technicians carry.

Heads up: Braemar uses the same code with different meanings on different product ranges, so check the model range shown next to the code.

Codes that mean switch the system off

If your Braemar unit shows 6, 19, 20, 21, 35, 49, EL, turn the system off at the isolator and leave it off. These faults involve the compressor, refrigerant or electrical protection, and running the unit can cause further damage.

The most serious Braemar fault codes explained

What does Braemar fault code 6 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control); on older TH series 5 star heaters code 6 instead means the OT4 over-temperature switch has opened)

The control board detected a flame signal at a time when no flame should be present, so the heater locked out as a safety measure.

Likely causes:

• Flame sensing circuit fault on the control board
• Older control board software (versions before V1.09 are more prone to this code)
• Follow-on from internal flame sense self-test codes 70 to 78

Safe checks before you call:

• Turn the heater off at the isolator or power point, wait 5 minutes, then turn it back on and press Retry on the wall controller if a message appears
• If the code returns after one reset, leave the heater switched off and book a licensed gas fitter

What does Braemar fault code 19 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control); codes 1 to 19 are also logged by older TH series heaters with the SpectroLink SCC controller)

The backup heat exchanger over-temperature switch (OT2) opened, which is a serious overheating safety shutdown.

Likely causes:

• Severe airflow restriction (blocked filter, closed outlets or crushed ducts)
• Primary over-temperature protection failed to act first
• Gas pressure set far too high
• Faulty OT2 switch

Safe checks before you call:

• Leave the heater switched off at the isolator and book a licensed gas fitter; this code needs a service-level reset

What does Braemar fault code 20 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control))

Flame roll-out was detected during start-up, meaning flame appeared outside the burner area, and the heater locked out.

Likely causes:

• Blocked or restricted heat exchanger or flue
• Burner cross-lighting slots obstructed
• Combustion airflow fault

Safe checks before you call:

• Leave the heater switched off at the isolator and book a licensed gas fitter; do not keep resetting this code

What does Braemar fault code 21 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control))

Flame roll-out was detected while the heater was running, meaning flame appeared outside the burner area, and the heater locked out.

Likely causes:

• Blocked or restricted heat exchanger or flue
• Combustion airflow fault developing during operation
• Burner problem needing inspection

Safe checks before you call:

• Leave the heater switched off at the isolator and book a licensed gas fitter; do not keep resetting this code

What does Braemar fault code 35 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control))

The flame roll-out safety circuit failed its self-check, so the heater locked out.

Likely causes:

• Flame roll-out switch or wiring fault
• Control board fault

Safe checks before you call:

• Leave the heater switched off at the isolator and book a licensed gas fitter

What does Braemar fault code 49 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control))

The heater locked out five times within 15 minutes, so it has shut down hard and needs an inspection and manual reset.

Likely causes:

• A recurring underlying fault (check the fault history for the codes that came before)
• Repeated resets without fixing the original problem

Safe checks before you call:

• Leave the heater switched off and book a licensed gas fitter; this code deliberately blocks further restarts until the heater is inspected

What does Braemar fault code EL mean? (Braemar ducted split refrigerated systems, including add-on cooling on ducted gas heating)

The system has been stopped by an emergency stop or fire alarm input.

Likely causes:

• Building fire alarm or emergency stop circuit activated
• Fault in the emergency stop wiring

Safe checks before you call:

• Check whether a building fire alarm or emergency stop has been activated before doing anything else

What does Braemar fault code 1 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control); codes 1 to 19 are also logged by older TH series heaters with the SpectroLink SCC controller)

The low pressure safety switch was already closed before the combustion fan started, so the heater will not begin its start cycle.

Likely causes:

• Pressure switch jammed closed or faulty
• Condensate or debris blocking the pressure switch hoses
• Blocked or restricted combustion fan suction fitting
• Damaged or shorted pressure switch wiring

Safe checks before you call:

• Turn the heater off at the isolator or power point, wait 5 minutes, then turn it back on and press Retry on the wall controller if a message appears
• If the code returns after one reset, leave the heater switched off and book a licensed gas fitter

What does Braemar fault code 2 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control); codes 1 to 19 are also logged by older TH series heaters with the SpectroLink SCC controller)

The low pressure safety switch failed to close after the combustion fan started, so the heater locked out after three attempts.

Likely causes:

• Combustion fan not running, jammed or faulty
• Blockage in the flue, combustion fan or pressure switch hoses
• Kinked, squashed or condensate-filled pressure switch hoses
• Faulty pressure switch stuck open

Safe checks before you call:

• Turn the heater off at the isolator or power point, wait 5 minutes, then turn it back on and press Retry on the wall controller if a message appears
• If the code returns after one reset, leave the heater switched off and book a licensed gas fitter

What does Braemar fault code 3 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control); codes 1 to 19 are also logged by older TH series heaters with the SpectroLink SCC controller)

The low pressure safety switch opened while the heater was running, which usually points to a combustion airflow problem.

Likely causes:

• Blocked or partially blocked flue
• High wind at the flue terminal
• Combustion fan slowing or failing
• Condensate in the pressure switch hoses

Safe checks before you call:

• Turn the heater off at the isolator or power point, wait 5 minutes, then turn it back on and press Retry on the wall controller if a message appears
• If the code returns after one reset, leave the heater switched off and book a licensed gas fitter

What does Braemar fault code 5 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control); also logged by older TH series 4 and 5 star heaters with the SpectroLink SCC controller; not applicable to 1-stage ICS models)

The duct temperature sensor (thermistor) is reading out of range because it is disconnected, shorted or faulty.

Likely causes:

• Thermistor unplugged from the control board
• Damaged thermistor cable
• Faulty thermistor

Safe checks before you call:

• Turn the heater off at the isolator or power point, wait 5 minutes, then turn it back on and press Retry on the wall controller if a message appears
• If the code returns after one reset, leave the heater switched off and book a licensed gas fitter

What does Braemar fault code 7 mean? (Braemar TQ and TQM series ducted gas heaters (ICS control board with MagIQtouch or SpectroLink wall control); codes 1 to 19 are also logged by older TH series heaters with the SpectroLink SCC controller)

The heater tried to light but could not detect a flame within the allowed time, and locked out after five attempts.

Likely causes:

• Gas supply turned off or gas pressure too low
• Dirty or worn flame sensing electrode
• Damaged or disconnected spark or flame sense lead
• Gas valve slow to open or not opening

Safe checks before you call:

• Check whether other gas appliances in the home (such as a gas cooktop) are working, which shows whether gas is available
• Turn the heater off at the isolator or power point, wait 5 minutes, then turn it back on and press Retry on the wall controller if a message appears
• If the code returns after one reset, leave the heater switched off and book a licensed gas fitter
