The E2 error on your Ge Dryer means the control board has detected a fault in the thermistor circuit, which monitors drum temperature. This is usually caused by a failed thermistor sensor or a loose wiring connection, and it often can be fixed without a technician visit.

Error code E2
Meaning Thermistor circuit fault — the temperature sensor is sending an invalid or missing signal to the control board
Severity Medium — the dryer may stop heating or shut off mid-cycle, but it is not a safety hazard
Time to fix 20–40 minutes
Tools needed Multimeter, Phillips screwdriver, nut driver

What the E2 error means

The thermistor is a small sensor located near the drum or heating element that tracks air temperature so the control board can regulate heat cycles. When the E2 code appears, the board is either receiving no signal, an out-of-range reading, or a short from that circuit. This can happen suddenly or build up over time as wiring insulation degrades or the sensor itself wears out.

Common causes

  • Failed or degraded thermistor sensor
  • Loose or corroded wire connector at the thermistor or control board
  • Damaged wiring harness from heat exposure over time
  • Lint or debris buildup interfering with the sensor
  • Faulty main control board (less common)
  • Poor ground connection causing electrical interference

How to fix the E2 error

  1. Unplug the dryer: Disconnect power at the outlet before opening any panels for safety.
  2. Locate the thermistor: Remove the back panel or front panel (depending on model) to find the thermistor, usually mounted near the exhaust duct or blower housing.
  3. Inspect wiring and connectors: Check for loose, corroded, or burnt connections at the thermistor and control board. Reseat any loose plugs.
  4. Test the thermistor with a multimeter: Set to resistance mode and check against the manufacturer’s spec (usually a few thousand ohms at room temperature). Replace it if the reading is zero, infinite, or unstable.
  5. Replace the thermistor if faulty: Install a manufacturer-approved replacement part, reconnect the wiring, and reassemble the panel.
  6. Power on and run a test cycle: Restore power and run a short heat cycle to confirm the E2 code has cleared.

FAQ

Can I keep using the dryer with an E2 error?
You can run cycles, but the dryer may not heat properly or could shut off mid-cycle, so it’s best to fix it soon rather than rely on air-dry only settings.

Do I need to replace the whole control board for an E2 error?
Usually not. Most E2 errors trace back to the thermistor or its wiring, and the control board is only at fault in rare cases after those parts test fine.

How much does a replacement thermistor cost?
Parts typically range from $10 to $30, and the repair is straightforward enough for most homeowners comfortable using a multimeter.
