Finally found someone in Vallarta (visiting from Canada) who was not afraid to tackle a computerized machine! Thank heavens, cuz we ran into one problem. The plugs did not match, new to old unit. The 2-wire connection with a 2-plug had to be taken apart, wires "appropriately" treated so they would fit into the New unit which had 3 holes! Beats me, but it works now!!! Sorry it took me so long, but I also had to move last summer during extreme humidity and heat, which knocked out my breathing...
