Diagnosis
The F1 error code on your NX60A range indicates a failure in the main oven temperature sensor circuit. The sensor can't report a temperature, so the oven shuts down heating for safety.
How to Fix It
The sensor itself is the most likely culprit. You'll need to replace the oven temperature sensor.
- Unplug the range or turn off the circuit breaker.
- Remove the oven racks and the rear interior panel (usually held by a few screws).
- Locate the sensor—a thin metal rod protruding into the oven cavity near the top rear.
- Disconnect the two wires from the sensor's terminal block at the back.
- Unscrew the single mounting nut holding the sensor to the oven wall from inside.
- Install the new sensor (part # DG94-00637A is common for this model), reconnect the wires, and reassemble.
If That Didn't Work
If the error persists with a new sensor, the wiring harness between the sensor and the main control board may be damaged or the main control board itself could be faulty. Inspect the wires for any pinches or burns near the oven broiler area.
Heads Up
The sensor is fragile. Be gentle when removing it—don't bend the rod. Always verify power is completely disconnected before starting.
