Changing From A 432 to a 542
You would need a control panel, timer, cycle switch, one extra knob and a complete wiring harness, I would guess it would cost you around $200+ depending whether you can buy parts at retail or dealer cost. There is little functional advantage in doing the switch, as a dealer we sell the 412 ten to one compared to both the 432 and 542 combined, it will still be the same washer when you are done.
Now if someone really wants to upgrade their SQ washer I do have the florescent light assembly from an Amana TOL washer, it just screws on and you only have to connect two wires to make it work, I put one on my SQ FL washer a few years ago. I will sell the assembly for $70+shipping.
