White Westinghouse Dishwasher Fuse Or Sensor

The High Limit Thermostat is an OEM replacement part for Frigidaire dishwashers. It is a temperature control device located in the dishwasher's heating assembly that monitors water temperature levels during cycles. 

The high-limit thermostat plays a crucial safety role by automatically shutting off the dishwasher's heating element if water temperatures get too hot, preventing potential burns or damage. It ensures the dishwasher maintains the proper temperatures required for effective cleaning.

Symptoms of a bad high-limit thermostat include: 

• Incomplete or ineffective cleaning even on short cycles  
• Lack of hot water or intermittent hot water during cycles
• Strange smells or visible steam emitting from the dishwasher
• The heating element fails to activate when needed

This OEM Frigidaire replacement part is also compatible with some Electrolux, Westinghouse, and Kenmore dishwasher models. 

This thermistor is the dishwasher's temperature sensor. It reports water temperature to the control so the heater and cycle timing are managed correctly, helping restore reliable wash performance and more consistent drying.

• Monitors water temperature in the tub/sump and sends readings to the control board
• Helps the control regulate heater operation and determine cycle progress/timing
• Failure can result in no heat or poor drying
• May cause unusually long/short cycles or temperature-related fault codes

• Disconnect power at the breaker and shut off the water supply before servicing
• Access is typically from the toe-kick/base area or sump; remove the lower access panel as needed
• Release the locking tab/clip, remove the sensor, and ensure the existing seal/O-ring is properly seated; install the new sensor fully to prevent leaks
• Reconnect the wire harness, restore power, and run a test cycle to check for leaks and proper heating
