Hello, I've got a Carrier Weather maker 8000 I unfortunately let the filter get way out of hand with the thermostat fan setting to on. The problem I'm having is error code #33, Ignites fine, inducer motor seems to run fine, but the blower doesn't seem to be working the burners run for about 5 minute or so then just go out. There's an obnoxious humming that I cannot pin point. Anyone have any ideas other then the blower motor itself?

Its possible you`ve burned up the blower motor can you get to it ,to lay your hand on motor is the humming coming from motor? Is it hot or very warm
