Second rinse happens even when single rinse selected

[ron3033]

Kenmore 110 20912991, 90 series, top load washer. With switch set to one rinse, the washer started doing second rinse. Does this suggest bad timer, or bad rinse selector switch. I sprayed contact cleaner on switches.... did not help. Other than this, washer works well and is not a rust bucket. It had a new transmission about 2 or 3 years ago. Am not in a position to afford a new washer now. Any ideas would be helpful, please.

Sounds like a bad (shorted/stuck) rinse selector switch or possibly a timer. A quick look on searparts website shows the timer and all but one of the selector switches are no longer available anyway. It doesn't show which switch is which, so as you are looking at the unit from the front left, which switch is the rinse selector? 

If that switch only controls the extra rinse and nothing else, you could try unplugging the connector to it and see if that stops the extra rinse, but without a wiring diagram and an ohm meter to check the correct switch contacts or to know what wire to unplug, it's just guessing. Might just need to keep using it as is and just feel better knowing your clothes are getting all the soap rinsed out of them!
