Before you decide on buying or purchasing, do your due diligence and double check the model number as well as make a visual inspection so that you are positive that the correct replacement ignition control board is being ordered. If you are unsure about the installation of the new ignition control board on your own then it is probably best to contact a professional to do the work for you.
