Kenmore Dryer Error Code tE2

The tE2 error code on a Kenmore dryer indicates that the electronic control has detected a shorted circuit condition in the thermistor. A thermistor is a temperature-sensing resistor whose resistance changes predictably as temperature changes. In a properly functioning dryer, the thermistor continuously sends resistance readings to the control board so the board can regulate heat output and protect the drum and load from overheating. When the control detects resistance values that fall outside the expected range on the low end, consistent with a short circuit, it triggers the tE2 fault and typically halts normal operation.

A shorted thermistor circuit means the resistance has dropped abnormally low, causing the control board to receive a signal that mimics an extremely high temperature reading. This can result in the dryer refusing to heat, shutting down mid-cycle, or failing to start at all. The fault can originate at the thermistor component itself, in the wiring harness connecting the thermistor to the control board, or at the connector terminals where corrosion or damage may create an unintended low-resistance path.

Diagnosing tE2 starts with measuring thermistor resistance using a multimeter with the dryer unplugged. The measured value should be compared against the thermistor resistance chart for your specific model, as expected resistance values vary by temperature. A reading near zero ohms or a very low resistance reading at room temperature confirms the thermistor is shorted and needs replacement. Technicians should also inspect the wiring harness and connectors for pinched wires, melted insulation, or terminal corrosion before condemning the thermistor itself.
