Wow Thank You alpinegreenneon ! This is just great information ! The fault hasn't come back yet.....famous last words.... I'll delve into this information should it come up again and the fault can be reset which I suspect it will as its happened at least a half a dozen times in the last four years give or take.......of course I've been fortunate in being able to reset each time to date. Again, Thank You kind sir, you are a great asset to all of us !!
