I have a question regarding the control board noted on the parts breakdown attached. This breakdown is dated March 2012 and references E17783447 for the control board. Since that time there is another control board that can be used with this unit that has a CN105 connection. My understanding is that these new boards were being used in production starting back in June2012. The new part # is E17B11447. Will the parts manual be changed to reflect the part number of the board that is installed in the unit. Both boards are good to use but depending on what controller you are hooking up you may need the E17B11447 (CN105) when ordering a replacement but you don’t know you need to because the parts breakdown only shows E17783447. Would it be possible for me to return the E17783447 for credit? Having the two different part numbers has caused me to be over stocked between these.
