Mike B Ann Arbor , MI January 03, 2017 Appliance: Model GE GTWN4250M1WS Washing maching surging when using any level of hot water on fill cycle After checking the water valve with a volt meter and checking the screen/filters on the intakes, I deduced the temp sensor could be the culprit. Ended up ordering and replacing the probe sensor ATC (temperature sensor). Okay now. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
