Repair Price: $176.00
Warranty: 12 months, extendable to 18 or 24 months.

Common faults:

  • False overheat fault (Code 10 or Code 19),
  • False ignition failure fault (Code 7),
  • False EFS shutdown fault (Code 11),
  • Incorrect thermistor temperature,
  • False thermistor faults (Code 4, 5, 15, 16),
  • Fan starts at full speed,
  • Fan speed not adjustable,
  • False condensate detected at start fault (Code 18).

Braemar Smart Control Fault Codes (3 STAR Models):

Code Fault Description
01 Pressure switch P-100 closed at start.  This fault is usually caused by a faulty Fenwal ignition module.
   
02 Pressure switch P-100 failed to close.

Check the following:
  • If the combustion fan does not start shortly after the thermostat is turned on (and the thermostat is set to a temperature higher than the current room temperature), the Fenwal ignition module is most likely faulty.
  • If the combustion fan does start shortly after the thermostat is turned on, but this fault code occurs, it may be due to a faulty pressure switch or condensate (water) buildup in the vacuum hose going to the pressure switch.  Disconnect the hose from the pressure switch end and blow through it to make sure it is clear of water or other blockages.  If there is water in the vacuum hose, the pressure switch may have a crack or hole in the internal diaphragm, and the pressure switch will need to be replaced, otherwise the hose will continue to accumulate water.  If the combustion fan is running and the pressure switch is working, the cause will most likely be a faulty BSC PCB.
   
03 Pressure switch P-100 open during run.
   
07 Ignition failure – Possible faulty/dirty flame sensor or false fault due to BSC PCB fault.

Check the following:
  • Ensure that all burners ignite during ignition.  If only some burners ignite, try cleaning the edge of the burner manifold closest to the gas jets with a small wire brush.  Be careful not to drop the brush into the heat exchanger.
  • Check that when the ignition module starts producing ignition sparks that the “GAS” LED on the BSC PCB is illuminated solidly, and is not pulsing or flickering.  If the “GAS” LED is off, pulsing or flickering, it will likely be due to a faulty BSC PCB.
  • If the burners ignite and the ignition spark stops within a second or so, you can assume that the ignition module is probably working correctly, and is not likely to be the cause of the fault.
  • If the Fenwal ignition module is producing sparks but the burners don’t ignite (or the gas valve doesn’t open), this will usually be caused by a faulty BSC PCB, however, there is also an over-temperature switch above the burners that has a manual reset button between the two terminals.  If this switch has tripped (open-circuit), there is a potential safety issue (rollout) and the heater must be serviced by a qualified gasfitter to ensure it is safe to use.
   
09 Internal memory failure – This is due to a faulty BSC PCB.
   
10 Over temperature switch HX OT1 open (tripped) – The heater may be overheating, the over-temperature switch may be faulty, the room fan motor run capacitor may be degraded or may have failed, or the BSC PCB may be faulty.

Check that the heater isn’t overheating due to an air flow issue.  Check that the return air filter is clean (if fitted, it should be behind the return air grille in the premises), check that all outlets in the premises are open and that there are no air flow obstructions (eg. closed doors) preventing the air in the premises reaching the return air grille.

Using a suitable multimeter, disconnect the room fan motor run capacitor (located near the BSC PCB inside the heater) and check that the capacitor is within 10% of the rated capacitance.  If not, replace the room fan run capacitor with the same capacitance and type.

If overheating is suspected, check that the fan blades do not have an excessive build-up of dust on them and that the room fan can rotate freely.

If the above items have been checked, the fault may be due to a faulty BSC PCB.
   
11 EFS shutdown – The Fenwal ignition module has shut down or the BSC PCB may be faulty.

This fault can be produced by a number of causes.

Check the following:
  1. Clean the flame sensor.
  2. Ensure that all burners ignite during ignition.  If not, try cleaning the edge of the burner manifold closest to the gas jets with a small wire brush.  Be careful not to drop the brush into the heat exchanger.
  3. If this fault code occurs in addition to intermittent code 7 faults, this may be due to a faulty Fenwal ignition module or faulty BSC PCB.  If the burners ignite and the ignition sparks stop approximately 1 second after the burners ignite, the fault will most likely be the BSC PCB.
   
19 Over temperature switch HX OT2 open at start.

If the heater is cold, this fault will be due to a faulty over-temperature switch or faulty BSC PCB.

If this fault occurs only after the heater has been running, check for problems that may cause an over-temperature condition (see code 10).
