I have Ruud Silhouttee furnase/air-conditioner and I have problem that for lower level in house the air keeps flowing but its not cold, temp of lower level keeps rising in-spite of air flowing (I can feel the air flowing out from duct is not cold). I also noticed that the outside fan for the lower level unit is not running. Unfortunately I do not have user manual as my earlier owner did not keep it, house is 8 years old. I checked that there is no water accumulation below the furnase unit (which I suppose can stop the operation). My guess is some fuse somewhere may have burnt but thought of asking for some advise before I try something stupid. Thanks for your help.

with air on,blowing warm air,take a stick or a long screwdriver and see if you can spin the outdoor fan blade.if its locked up you need a new fan motor,if it spins you might need a capacitor,or a contactor.does the compressor run without the fan on??

Thanks for the response. Yes, I am able to move the fan blade with screw driver. Not sure if compressor is running, if I stand in front of the furnase unit something is running as its making noise. Is there anything more I can do or I need to call technician?

I just tried flipping the outside and inside cuircuit breaker to Off and On just to see in case anyone had tripped but no luck with that.

Thanks

you will be able to hear the compressor running inside the outdoor unit justbelow the fan.sounds like a refrigerator running.you should call for service.
