    Rheem furnace
    My Rheem furnace is showing a diagnostic red flashing light, flashing 3 times.
    I cannot locate the manual on the furnace. Does anyone know what the 3 time flashing red light means?

    Model #? Most Rheems use a green diagnostic light. You can't find the codes on the schematic diagram?
