I have a Whirlpool stackable washer/dryer, model #WET3300SQ. Occasionally, the water temperature is as it should be. Other times, however, it will fill with hot or warm water when set to cold, and vice versa. My first impression was that the temperature control switch (part #W10114118) must be bad, but figured it wouldn't hurt to get a second opinion before ordering. I understand that some people have had similar problems with a faulty inlet valve, but it seems that the problems were more consistent in those cases (washer would only supply hot or cold on all settings). Any suggestions/diagnoses would be greatly appreciated!
