Does anyone know where I can find Ducane parts-- or substitutes for-- NH0C084AH03 and AG736031 DRC-10A (fan control center and universal relay)? My HVAC company says these are obsolete, there are no substitutes by other companies, and I need a whole new unit--this just seems impossible to me... Can anyone out there help? Thank you! Lora_B

Have you tried talking to these people?
