Furnace in the crawl space had water in the draft motor keeping the system from running. Remover motor to drain water, also removed drain trap and removed a bug from trap. Reassembled everything and unit is working again. I had noticed a burning smell while in the crawl space and started seeing smoke coming from the steam humidifier and power cord connected to it. I unplugged the unit and took some pictures. I think there was some sort of recall with a part on the humidifier. I will check with my service manager on this situation.
