GE Range Error Code Cycle light 3 flashes then 4s OFF, Clean light ON

This error code indicates an A/D Stuck fault, meaning the analog-to-digital converter circuit on the main control board has stopped cycling through its conversion process. The A/D converter is responsible for reading sensor signals, such as oven temperature, and translating them into data the board's processor can use. When it becomes stuck, the range cannot reliably monitor or control oven functions. The Clean light being on alongside this code suggests the fault is tied to the oven's temperature monitoring system.

It is not advisable to continue using the range while this error is active. An A/D Stuck condition means the control board cannot reliably read sensor data, which may prevent the oven from regulating temperature accurately. This could pose a risk of overheating or uncontrolled operation. Power off the range until the fault is diagnosed and resolved.

Repair costs depend on the root cause. If the issue is a wiring harness problem, costs may be limited to a service call fee, typically in the range of $75 to $150. If the main control board requires replacement, parts alone can range from $150 to $350 or more depending on the model, with total repair costs including labor often falling between $250 and $500. Getting a diagnostic estimate from a technician before committing to repair is a good approach.

Some DIYers can address this error by first checking and reseating wiring harness connectors at the control board and temperature sensor, which requires basic electrical safety knowledge. If the wiring is intact, the repair typically involves replacing the main control board, which is a more advanced task but is achievable for experienced DIYers comfortable working with appliance electronics. If you are unsure about working with high-voltage components, a licensed technician is recommended.

Disconnecting the range from power for several minutes and restoring it may temporarily clear the error if the fault was caused by a logic or firmware glitch on the control board. However, if the error returns after a reset, this points to a hardware failure in the control board or a wiring issue that requires physical diagnosis and repair. A reset alone is not a permanent solution.
