Bryant 352MAV and error code 12
I have the Bryant 352MAV 2-stage furnace that is giving me problems:
When the thermostat is set below the target temperature i.e. 19C/68F the LED code indicator (on the logic board) is steady ON, once the target temperature is set i.e. 24C/78F , the inductor motor comes on for perhaps 15 sec, then it cots out, then the blower motor kicks in for about 30-45 sec, then the HSI starts glowing and soon after there is a gas ignition. And then it all stops! The gas cuts out, the blower motor stops and the LED code indicator flashes 12 (one short and two long), after a short while the whole process repeats, over and over again. Any suggestion on how to get the heat going again is much appreciated. |
