E3 — Inlet thermistor shorted

The inlet (drum) temperature sensor is reading a short (near 0 ohms), so the control sees an impossible inlet temperature and cuts the heat. Per GE's factory service documentation, the fix is to check and replace the inlet thermistor if necessary.

The fix

Inlet thermistor

Inlet thermistor shorted

$15-30 moderate difficulty 30-45 min Tools: multimeter, nut driver, screwdriver

Diagnose first: Measure inlet thermistor resistance at the heater housing — near 0 ohms indicates an internal short (replace the sensor). Also check for harness insulation chafed against the chassis, which can produce the same short.

How to fix it

  1. Unplug the dryer.
  2. Remove the panel needed to access the inlet thermistor near the heater housing (this is the inlet sensor, not the outlet/exhaust sensor).
  3. Disconnect the thermistor and measure resistance with a multimeter — expect roughly 10K ohms at room temp; near 0 ohms means it's shorted.
  4. If shorted, replace the inlet thermistor.
  5. Inspect the harness for chafe points against the chassis and clean any lint or corrosion from the connector.
  6. Reassemble, restore power, and run a cycle. If E3 returns with a verified-good thermistor and harness, have the control board checked.

Why it happens

Typical signs: E3 on display · Heat cuts out shortly after the cycle starts · No heat or very low heat · Sensor Dry cycles end early

  • Shorted inlet thermistor Internal element shorted, reading near 0 ohms instead of roughly 10K ohms at room temp.
  • Harness shorted to chassis Wire insulation chafed where the harness passes through sheet metal near the heater housing.
  • Lint or moisture bridging the connector Conductive lint paste or moisture across the sensor's spade terminals can mimic a short.

Frequently asked questions

What does the E3 code mean on a GE dryer?

The inlet (drum) temperature sensor is reading a short (near 0 ohms), so the control sees an impossible inlet temperature and cuts the heat. Per GE's factory service documentation, the fix is to check and replace the inlet thermistor if necessary.

What causes the E3 code on a GE dryer?

Shorted inlet thermistor: Internal element shorted, reading near 0 ohms instead of roughly 10K ohms at room temp. Harness shorted to chassis: Wire insulation chafed where the harness passes through sheet metal near the heater housing. Lint or moisture bridging the connector: Conductive lint paste or moisture across the sensor's spade terminals can mimic a short.

Is it safe to keep using a GE dryer with a E3 error?

Yes, with caution. This is rated a moderate-severity fault.

How do I fix E3 on a GE dryer?

Unplug the dryer. Remove the panel needed to access the inlet thermistor near the heater housing (this is the inlet sensor, not the outlet/exhaust sensor). Disconnect the thermistor and measure resistance with a multimeter — expect roughly 10K ohms at room temp; near 0 ohms means it's shorted.
