The E1 error on your Whirlpool Dryer means there’s a problem with the thermistor or temperature sensor circuit. This sensor monitors the internal temperature, and when it malfunctions or reads incorrectly, the dryer stops to prevent damage.

Error code E1
Meaning Thermistor or temperature sensor malfunction
Severity Medium — Dryer won’t operate until resolved
Time to fix 30–60 minutes
Tools needed Multimeter, screwdriver set, nut driver (1/4″)

What the E1 error means

The E1 error code indicates that your Whirlpool dryer’s control board has detected an issue with the thermistor circuit. The thermistor is a temperature-sensing resistor that monitors the air temperature inside the drum and sends this information to the control board. When the control board receives readings outside the expected range—typically indicating an open circuit, short circuit, or resistance values that don’t match normal operating temperatures—it triggers the E1 error and shuts down the dryer to protect internal components from overheating or other damage.

Common causes

  • Faulty or failed thermistor that needs replacement
  • Loose or corroded wire connections between the thermistor and control board
  • Damaged wiring harness with broken or frayed wires
  • Defective control board unable to read thermistor signals correctly
  • Moisture or debris affecting the thermistor’s electrical connections
  • Thermistor dislodged from its mounting position on the blower housing

How to fix the E1 error

  1. Unplug the dryer and access the thermistor: Disconnect power to the dryer completely. Remove the front or rear panel (depending on your model) to access the blower housing where the thermistor is located. The thermistor is typically a small sensor with two wires attached, mounted near the heating element or on the blower housing.
  2. Inspect wiring and connections: Check all wire connections leading to the thermistor for looseness, corrosion, or damage. Ensure the wire harness connector is firmly seated. Look for any frayed, pinched, or broken wires along the path from the thermistor to the control board. Reconnect any loose wires and clean corroded terminals.
  3. Test the thermistor with a multimeter: Disconnect the thermistor wires and set your multimeter to measure resistance (ohms). At room temperature (approximately 70°F), the thermistor should read between 10,000 and 12,000 ohms. If the reading is infinite (open circuit), zero, or significantly outside this range, the thermistor has failed and needs replacement.
  4. Replace the thermistor if defective: If testing confirms the thermistor is faulty, order a replacement part specific to your Whirlpool dryer model (typically $15–$40). Remove the old thermistor by disconnecting the wires and unscrewing or unclipping it from its mount. Install the new thermistor in the same position and reconnect the wires securely.
  5. Check the control board (if thermistor tests good): If the thermistor tests within normal range and all connections are secure, the control board may be faulty. Inspect the control board for visible signs of damage, burnt components, or corrosion. If damaged, the control board will need professional replacement as this is a more complex repair.
  6. Reassemble and test the dryer: Once repairs are complete, reattach all panels and restore power to the dryer. Run a test cycle to verify the E1 error has cleared and the dryer operates normally with proper heating and temperature control.

FAQ

Can I continue using my Whirlpool dryer with an E1 error code?
No, you should not use the dryer when the E1 error appears. The dryer will not operate properly because the control board cannot accurately monitor temperature, which creates a safety risk for overheating and potential fire hazard. The dryer is designed to shut down when this error occurs to protect your home and the appliance.

How much does it cost to fix the E1 error on a Whirlpool dryer?
If you repair it yourself, a replacement thermistor costs between $15 and $40, which is the most common fix. If you hire a professional technician, expect to pay $150–$300 including the service call, labor, and parts. Control board replacement, if needed, can cost $200–$400 for parts and labor combined.

How do I know if the thermistor or control board is causing the E1 error?
Test the thermistor first using a multimeter to check its resistance at room temperature (should be 10,000–12,000 ohms). Also inspect all wiring for damage or loose connections. If the thermistor tests within the normal range and all connections are secure, the control board is likely the problem and will need professional diagnosis or replacement.
