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.

Every Braemar fault code at a glance

Some models show faults as a flashing-light pattern instead of a code; documented lamp patterns are listed alongside their codes.

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
