carrier weather maker won't stay lit
I'll start with the startup process. First of all the blower is always on high, I push the reset button turn the thermostat and the gas knob on. The inducer starts turning and about 10-15 seconds after that the blower turns off. The HSI starts glowing red and then the gas relay is tripped by the controal unit and the burners turn on, about 65 seconds of the burner being on the blower starts back up and about 10-15 seconds after that the burners shut off and the blower is stuck on. if i turn the thermostat blower position to off it keeps going. I tried moving the sensor out of the way of the flame and the burners only stay on for about 3 seconds. I initiated the self test feature and I herd all the relays on the controal unit turn on and off with the accompanying devices when applicable. Why won't my bruners stay on and why won't the blower turn off, I have a feeling the two problems are related.

Thanks in advance

this needs to be in the HVAC section. Do you have flashing LED on the control board ? If so, count flashes & look up the code. Sounds like flame failure is the reason burners won't stay on
