Braemar Fault Code 32

Fault: Combustion air pressure too low at start.

Potential Cause (Technical Use Only: Potential remedy):

• Combustion fan not operating.  Check that power is supplied to motor when required – replace combustion fan if not running with power applied. 
• Combustion fan motor or fan wheel dislodged or jammed.  Check motor mounts – rectify if required. 
• Combustion fan wiring disconnected or damaged.  Re‐connect or replace wiring. 
• Combustion fan suction hose disconnected or damaged between combustion fan and ICS combustion air pressure sensor.  Re‐connect or replace combustion fan suction hose. 
• Combustion fan blocked.  Check and un‐block combustion fan. 
• Condensate blocking combustion fan suction hose.  Clear blockage.  Check flue condensate drain fitted correctly (condensing models only). 
• Swarf obstructing combustion fan pressure tapping.  Check both ends of pressure tapping – clear obstruction or replace pressure tapping. 
• Flue system blockage.  Check and clear blockage. 
• Severe wind on flue terminal, or poor flue terminal location (eg, too close to roof).  Check flue terminal location – re‐ locate if necessary. 
• Faulty combustion air pressure sensor.  Check suction pressure – if sufficient, and fault recurs, replace pressure sensor on ICS (cut cable tie, un‐plug pressure sensor PCB, re‐connect new pressure sensor, fit new cable tie).
