Have a Carrier Model 58STA furnace with status code 33.
It's about 8 years and the 1st row will ignite (usually) but not the 2nd & 3rd rows. If I fan them, they will ignite. Tried the basic stuff in the manual and it ran OK last night. Today tried to clean a bit better, back to the above. Replaced filter, checked all connections, blower wheel is not loose and it is not windy out today.
E are however in the greater NW suburbs of Chicago, 0 degrees now and -5 last night, so not good timing. Any ideas how to isolate what's left; IE: switches, roll out switch or blower motor? Thanks in advance, Charlie
