Quick answer
Thermistor failure.
Model compatibility: GE reuses codes across series and model years, so 6A may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Thermistor failure.
Signs
Symptoms you may notice
Operation may stop when the control sees an implausible reading.
The code may return shortly after startup or during the affected cycle stage.
Temperature-related performance can become inconsistent.
Other components may be disabled because the control cannot trust the sensor input.
Why it happens
Possible causes
A sensor or thermistor that has drifted outside its expected range.
Wiring damage between the sensor and the main control.
An open, shorted, corroded, or loose sensor connection.
Moisture/temperature conditions affecting the sensor circuit.
A control-board input fault after the sensor and harness are verified.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Do not disconnect internal sensors just to “test” whether the code clears; that can create additional faults.
Note whether the code appears immediately or only after heating/cooling begins; that timing is useful for diagnosis.
Power the appliance off once and allow it to restart normally if there is no leak, overheating, or electrical damage.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
