What tE1 means on a Kenmore dryer

The tE1 error code on a Kenmore dryer indicates that the electronic control board has detected an open circuit condition in the thermistor circuit. The thermistor is a temperature-sensitive resistor that continuously monitors drum or exhaust air temperature and feeds that data to the control board. When the circuit is open, no valid resistance signal is being received, so the control board cannot regulate heating cycles and flags the fault to prevent unsafe operation.

An open circuit in the thermistor path typically means the resistance has climbed beyond the expected range on the thermistor resistance chart, which correlates resistance values to specific temperatures. Under normal conditions, thermistor resistance decreases as temperature rises. An open circuit reading, effectively infinite resistance, tells the control board the sensor is either disconnected, broken internally, or has a wiring fault somewhere along the signal path between the thermistor and the control board.

The most common causes are a failed thermistor component itself, a broken or corroded wire in the harness connecting the thermistor to the control board, or a loose connector at either end of that circuit. Because the dryer will typically suspend heating or refuse to run properly when this fault is active, diagnosing it promptly is important. The first step is measuring thermistor resistance with the dryer unpowered and comparing the reading against the thermistor resistance chart to determine whether the sensor or the wiring is at fault.

Common causes of tE1

  1. 01

    Failed thermistor

    Part replacement

    The thermistor itself has failed internally and now reads infinite resistance instead of a value within the expected range. Confirm by measuring resistance across the thermistor terminals with power off and comparing to the thermistor resistance chart.

  2. 02

    Broken or disconnected wiring harness

    Wiring / connection

    A wire in the harness running from the thermistor to the control board has broken, corroded, or pulled out of a connector. Visually inspect the full length of the harness and tug gently on each connector to check for loose terminals.

  3. 03

    Loose connector at the thermistor or control board

    Wiring / connection

    The connector at either the thermistor end or the control board end may have vibrated loose over time, interrupting the signal circuit. Unplug and firmly reseat both connectors and recheck for the fault.

  4. 04

    Corroded or damaged connector terminals

    Part replacement

    Moisture or heat exposure can corrode the metal terminals inside the wiring connectors, creating high resistance or an open circuit even when the connector appears seated. Inspect terminals for discoloration, pitting, or oxidation and clean or replace as needed.

  5. 05

    Faulty electronic control board

    Part replacement

    If the thermistor and all wiring check out correctly with a meter, the control board itself may have a defective input circuit that is falsely reporting an open condition. This is the least common cause and should only be considered after all other components are confirmed good.

Frequently asked questions about tE1

What does tE1 mean on a Kenmore dryer?
The tE1 code means the electronic control board has detected an open circuit in the thermistor, which is the temperature sensor that monitors dryer heat. The control board is receiving no valid resistance signal from the thermistor, so it cannot safely regulate the heating system. This is typically caused by a failed thermistor, a broken wire, or a loose connector in the thermistor circuit.
Can I fix a tE1 error on my Kenmore dryer myself?
Many tE1 repairs are within reach for a DIYer who is comfortable using a multimeter. Start by measuring the thermistor resistance with the dryer unpowered and comparing it to the thermistor resistance chart for your model. If the thermistor reads infinite or out-of-range resistance, replacing the thermistor is a straightforward repair. If the thermistor tests good, inspect the wiring harness and connectors for breaks or loose terminals.
Is it safe to run my Kenmore dryer with a tE1 error?
It is not recommended to run the dryer while the tE1 fault is active. The thermistor is a key safety and control component that allows the board to regulate temperature, and operating without a valid temperature signal could result in uncontrolled heating or unexpected shutdowns. Address the fault before continuing normal use.
Will resetting my Kenmore dryer clear the tE1 error?
Resetting the dryer by unplugging it for a few minutes may temporarily clear the displayed code, but the tE1 error will return as soon as the control board checks the thermistor circuit again and finds the open condition still present. A reset does not fix the underlying problem. The thermistor or wiring issue must be diagnosed and repaired for the code to stay cleared.
How much does it cost to repair a tE1 error on a Kenmore dryer?
If the thermistor itself is the cause, the part typically costs in the range of $10 to $35, making it one of the more affordable dryer repairs. If a wiring harness or connector needs replacement, costs can vary but often remain in a similar range for parts. Professional labor charges will add to the total, generally bringing a service call repair to somewhere between $100 and $250 depending on your location and the extent of the fault.
