I'm in Maui HI ad there is a 4-5 hr time difference so I need to get up early to call, but they always answer and give good advice It may take a couple of days because of the time zone but it gets solved. It helps if you have tools ready, meters if you have them, Machine documentation Model, serial, year from the tag on the machine, They have records on every machine and its options on hand.
