Dryer runs a complete cycle but produces no heat — a failed thermistor sends incorrect temperature signals to the control board, cutting power to the heating element.
Clothes remain damp after a full cycle because the thermistor is misreading exhaust temperature, causing the control board to underpower the heating element.
Samsung dryer displays tE or HE fault codes indicating a temperature sensor error — replacing the DC32-00007A thermistor clears the fault and restores normal operation.
Dryer stops mid-cycle prematurely because a defective thermistor reports falsely high temperatures, triggering an early safety shutdown.
A thermistor reading near zero ohms fails to regulate heating cycles, allowing the element to run unchecked and overheat the drum — potentially blowing the thermal fuse.
💡 Pro Tip: How to Know If Your Thermistor Is Bad
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer runs a full cycle but produces no heat at all
⚠️ Clothes are still damp after a normal cycle — takes too long to dry
⚠️ Dryer displays tE, HE, or temperature-related error codes
⚠️ Dryer starts then shuts off too soon or overheats
🔬 Diagnostic Tip: Thermistors do not test for continuity — use a multimeter set to ohms. At room temperature (77°F), a healthy DC32-00007A reads approximately 10,000 ohms. While the dryer is unplugged, blow warm air over the sensor with a hair dryer — resistance should decrease as temperature rises. If resistance stays fixed or reads near zero, the thermistor has failed and must be replaced. Also inspect nearby DC47-00016A thermal fuse; when one fails, the other is often stressed — replace both together for best results.
