I have a Kenmore Series 80 washer, Model 110.82882800. I'm not sure
how old it is since it came with the house, maybe 15 years. It has
"Electronic Temperature Control" and it's driving me nuts.
On "cold" wash, the cold water valve is always open, but the hot
alternates on and off. This isn't a huge problem because it seems to
want to make the water not so cold, and may even be behaving normally.
I know it's actively controlling this because if I turn off the cold
water supply, within seconds it closes the hot water valve.
Now if I switch to "warm" wash, the hot water valve is always open, and
the cold water valve stays open for a few seconds....then turns off.
Meaning "warm" wash ends up being scalding hot.
There's obviously nothing wrong with the valves. This control board is
switching a TRIAC on and off to control one of the valves, but it's
temperature judgement isn't that good.
Any suggestions? Is the thermistor known to go bad? The control board
visually looks ok. I don't even have an owners manual for this thing.
