GE Dryer Error Code E24

E24 on a GE dryer indicates a short circuit detected in the control NTC thermistor circuit. The control thermistor is a resistance-based temperature sensor, and it should read approximately 50K ohms at room temperature. When the dryer's electronic control detects a short in this circuit, it triggers E24 to signal that temperature monitoring is compromised. The fault can originate in the thermistor itself, the wiring harness, or the control board.

It is not recommended to continue running the dryer while E24 is active. The control thermistor provides temperature feedback that the electronic control uses to regulate heat levels. Operating the dryer without reliable temperature sensing could result in overheating or unpredictable cycle behavior. The dryer should be kept out of service until the fault is identified and repaired.

Repair costs depend on the root cause. A replacement control thermistor is typically an inexpensive part, often in the range of $15 to $40. If the wiring harness needs repair, costs vary based on the extent of damage. An electronic control board is the most expensive possibility, generally ranging from $100 to $250 or more for the part alone. Adding professional labor will increase the total cost of any of these repairs.

A knowledgeable DIYer can diagnose and often fix E24 by using a multimeter to measure the control thermistor's resistance after disconnecting its wires. If the reading falls outside 45K to 55K ohms, replacing the thermistor is a straightforward repair. If the thermistor tests good, inspecting and repairing the wiring harness is also manageable, but replacing the electronic control board requires more confidence working with appliance electronics.

A power reset may temporarily clear the E24 code from the display, but if the underlying short circuit condition still exists in the thermistor or its wiring, the code will return once the dryer runs through its diagnostic checks. Resetting alone does not fix the root cause and should not be used as a substitute for proper diagnosis and repair.
