By: Whirlpool
Part Number: OEM18049497
Manufacturer Part Number: WPW10184148

The Water Temperature Switch is an OEM replacement part for Whirlpool washing machines. This switch monitors incoming water temperatures to ensure they fall within the thresholds required for selecting dependent wash cycles. It plays an important safety function by preventing the activation of vulnerable "hot" cycles if water is too cool. 

Causes of a bad water temperature switch can include failures from repetitive heating/cooling cycles, mineral deposits obstructing sensors over time, or defective temperature sensing mechanisms.

Symptoms of a bad water temperature switch include:

  • Inability to select high-temperature cycles  
  • Fault codes related to water supply temperatures
  • Potential improper washing if the temperature reading is inaccurate

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Hello Kevin. According to the wiring diagram, yellow/red is the hot wire for the cold water valve. You will need to test and see if you have power across the white wire and the yellow/red wire at the ATC switch WPW10184148 with the unit on a cold fill. If so, you will need to look and see if there is a broken or burnt wire or trace and see where your loosing the power to the valve at. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps.http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
