How to Diagnose and Fix a Washing Machine with a Faulty Thermistor
A washing machine that fails to maintain consistent water temperature often points to a sensing problem rather than a heating fault. Incorrect readings can affect cycle timing and overall wash performance. Accurate diagnosis depends on understanding how temperature indication regulates machine operation. Over time, homeowners may observe uneven heating due to wiring wear, sensor drift, or abnormal resistance within the washer thermistor. When testing confirms unreliable readings, replacing the component becomes a corrective step rather than a preventive measure. Key aspects of focus include: Identifying temperature-related symptoms that signal sensing inaccuracies Diagnosing the washer thermistor using systematic inspection and electrical testing Verifying whether the fault originates from the sensor or associated connections Applying long-term fixes that restore consistent heating performance Reducing future issues through preventive checks and proper installation practices Thi...
