What To Know
- This sensor measures the temperature inside the drum and ensures that the dryer operates at the appropriate heat level.
- When the sensor malfunctions or becomes disconnected, the dryer displays error code E20 as a safety precaution.
- A clogged lint trap or exhaust vent can restrict airflow and cause the dryer to overheat, triggering error code E20.
If you’re facing the dreaded GE dryer error code E20, don’t panic! This comprehensive guide will empower you to diagnose and resolve the issue, restoring your dryer to its optimal performance. By following these detailed steps, you’ll save time, money, and the frustration of a non-functioning dryer.
Understanding Error Code E20
The GE dryer error code E20 indicates a problem with the dryer’s temperature sensor. This sensor measures the temperature inside the drum and ensures that the dryer operates at the appropriate heat level. When the sensor malfunctions or becomes disconnected, the dryer displays error code E20 as a safety precaution.
Step-by-Step Troubleshooting
1. Reset the Dryer
Unplug the dryer from the power outlet and wait for 5 minutes. This will reset the dryer and potentially clear the error code.
2. Check the Power Supply
Ensure that the dryer is properly plugged into a working power outlet. Test the outlet with another appliance to rule out any electrical issues.
3. Inspect the Door Switch
The door switch activates the dryer’s heating element when the door is closed. Check if the switch is loose, damaged, or misaligned. Replace the switch if necessary.
4. Clean the Lint Trap and Exhaust Vent
A clogged lint trap or exhaust vent can restrict airflow and cause the dryer to overheat, triggering error code E20. Clean both components thoroughly.
5. Examine the Temperature Sensor
Locate the temperature sensor inside the dryer drum. Check if it’s loose, disconnected, or damaged. Clean the sensor with a soft cloth and reconnect it securely.
6. Test the Heating Element
Disconnect the dryer from power and use a multimeter to test the heating element for continuity. If the element is faulty, replace it.
7. Inspect the Wiring
Examine the wiring harness connecting the temperature sensor and heating element to the control board. Check for loose connections, damaged wires, or shorts. Repair or replace the wiring as needed.
Advanced Troubleshooting
If the above steps fail to resolve error code E20, consider the following advanced troubleshooting options:
1. Replace the Control Board
The control board is the “brain” of the dryer and manages various functions, including temperature regulation. If the control board malfunctions, it may cause error code E20.
2. Contact a Professional
If all troubleshooting attempts fail, it’s advisable to contact a qualified appliance repair technician. They have the expertise and tools to diagnose and fix the issue accurately.
Troubleshooting Tips
- Safety first: Always unplug the dryer from power before performing any troubleshooting or repairs.
- Use genuine GE replacement parts: To ensure optimal performance and safety, use only original GE parts when replacing components.
- Consult the user manual: Refer to your dryer’s user manual for specific troubleshooting instructions and safety guidelines.
Beyond Error Code E20: Common Dryer Problems
While error code E20 is a common issue, several other problems can affect GE dryers:
- Clothes not drying: Check the lint trap, exhaust vent, and temperature sensor.
- Dryer overheating: Clean the lint trap, exhaust vent, and inspect the heating element.
- Dryer making noise: Inspect the drum bearings, belt, and pulley for damage or wear.
- Dryer not starting: Check the power supply, door switch, and control board.
