WPW10195091 Whirlpool Dishwasher Thermostat

Dishwasher Thermostat Overview

The High Limit Thermostat is a genuine OEM replacement part tailored for use in Whirlpool dishwashers, though it is also compatible with several other brands including Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. Additionally, Whirlpool manufactures compatible parts for Sears-Kenmore and Ikea appliances. This thermostat is crucial for monitoring the water temperature in the dishwasher tub to ensure it stays within safe operating limits. It functions as a switch and maintains continuity when it operates properly, indicated by a zero-ohm reading that reflects a closed circuit. You can find it at the base of the tub where it has direct contact with the water throughout the cycle.

For safety, always disconnect the dishwasher from the power supply or switch off the house circuit breaker before you begin the installation of this part.

Signs of a Malfunctioning High Limit Thermostat:

1. Poor cleaning or drying results.
2. Overheating within the dishwasher.
3. The dishwasher turns off by itself during cycles.
4. Strange sounds or smells during operation.

These symptoms suggest that the thermostat may not be functioning correctly and could require a check or replacement to ensure optimal performance and safety.
