GE Dryer Error Code 003

Error code 003 on a GE dryer indicates an Inlet Thermistor Open fault. The control board monitors the inlet thermistor's readings, and when high or out-of-range readings accumulate beyond a count of 10, this error is set. It signals that the temperature sensor at the dryer's air inlet has likely failed or lost its electrical connection. The dryer needs the thermistor and its wiring inspected before normal operation can resume.

Running the dryer with an active 003 error is not recommended. The inlet thermistor provides the control board with temperature data used to regulate heat levels safely. Without accurate sensor input, the dryer cannot properly manage heat, which could lead to overheating or inconsistent drying performance. Resolve the fault before returning the dryer to regular use.

A reset may temporarily clear the error code, but it will return if the underlying problem with the inlet thermistor or its wiring has not been corrected. The control board sets the fault only after 10 out-of-range readings have accumulated, so the reset provides no lasting fix. The thermistor and wiring must be inspected and repaired or replaced to permanently clear the code.

Yes, a mechanically inclined DIYer can often resolve this error by inspecting and replacing the inlet thermistor. Start by unplugging the dryer, locating the inlet thermistor, and checking its wiring connector for looseness or corrosion. If the connector is secure and the thermistor tests open with a multimeter, replacing the thermistor is the correct repair. Always disconnect power before working on any internal components.

If only the inlet thermistor needs replacement, the part itself typically costs in the range of $10 to $40 depending on the specific model. If you hire a technician, labor will add to that cost, generally bringing the total repair into the $80 to $200 range. If the issue is simply a loose connector, the repair may cost nothing beyond your time.
