I have an older Kenmore All in One stacked washer/dryer unit. The lid switch for the washer is bad, and I am looking for a replacement. The label plate is worn, and I cannot make out one of the numbers, but from what I can read the model number is 417?89670800, with the ? replacing the unreadable number. There also appears to be a manufacture date of 1/88 on the plate, so the unit appears to be nearly 20 years old. I would like to repair the unit if possible, as it still works well, but I am having trouble finding a replacement part without the complete model number. If anyone could help with the model, or part, number, I would appreciate it.
