I am trying to locate a furnace model number, the furnace looks like a Rheem or a Ruud but has no markings of either on it, I have a model number I took off the furnace but I cant find it on line anywhere.
Any help would be greatly appreciated
had blower motor replaced per hvac contractor. did not solve problem. demand on motor but it hums. old motor bench tested okay. what tells motor to fire up. stat is okay. furnace fires up but shuts down when motor does not start
