Dryer drum spins but generates no heat or not enough heat to dry clothes; thermistor is sending an out-of-range signal to the control board, preventing the heater from energising.
Dryer stops mid-cycle (typically 5–10 minutes in) with indicator lights flashing; a failed thermistor causes the board to misread drum temperature and trigger a premature shutdown.
Clothes remain damp after a full cycle because the thermistor is reporting falsely low temperatures, causing the board to run the heater below optimal output.
Control panel displays fault codes such as E5b or E71, indicating the thermistor resistance is outside the expected range and the control board has flagged a temperature-sensor fault.
💡 Pro Tip: How to Diagnose a Faulty Control Thermistor
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer runs but produces no heat or insufficient heat
⚠️ Cycle shuts off too soon (5–10 minutes in) or runs excessively long
⚠️ Control panel displays error codes E5b, E71, or other temperature-related fault codes
⚠️ Clothes come out still damp, or drum runs too hot to handle
🔬 DIY Test: Set your multimeter to the 200K Ohms range. At ~77°F room temperature the thermistor should read approximately 47,000–50,000 Ohms. A reading of only a few hundred Ohms, an open circuit (OL), or a value that does not change when gently warmed by hand indicates a failed thermistor that needs replacement.
