What 002 / 004 Means
002 and 004 report the outlet thermistor - the sensor in the exhaust path - as defective. These numeric codes come from the GFD-series GE dryer chart and are read out of the control rather than shown during a normal cycle, so the same number means something different on GE washers. The control uses inlet and outlet readings together to judge how the load is drying; with the outlet sensor unreliable, cycle length and heat control both suffer.
Common Causes of 002 / 004
- Failed outlet thermistor
- Lint packed around the sensor
- Damaged sensor wiring or loose connector
- Control input fault
- Restricted exhaust pushing readings out of range
🔧 One Safe Check You Can Try
Before anything electrical, deal with airflow: clean the lint screen (and wash off any fabric-softener film with warm water), pull the dryer out and check the vent hose and the duct to the outside are clear, and confirm strong airflow at the outside vent with the dryer running. Restricted venting is both the most common cause of heat complaints and a fire risk in its own right. Then power the dryer down at the breaker for a minute and restart. If the code remains, the sensor or its harness needs service.
⚠ Why You Shouldn't Go Further Than That
- The parts involved are inside the cabinet, and an electric dryer runs on a 240 V circuit - the terminal block and heater connections are not owner territory.
- Sensor confirmation needs resistance measurements at a known temperature, not guesswork.
- Damage caused during a repair attempt may not be covered - check your warranty terms first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
