Efrain for Model Number NX58F5500SW/AA-0000 When I set the oven temperature it never reaches the set temperature., ie if I set it for 400 degrees Fahrenheit it heats up to 310 or 350 degrees. The display shows the temperature with a red blinking light showing it is set to heat to 400 degrees but it never reaches 400 degrees. It stays at 310 or 350 or close to 400 but does not reach 400 degrees. Other days it works ok . Do I need to replace the Sensor-Thermistor ?
Answer Efrain, Being that this is a "gas" range, and there are no error codes mentioned, or issues with the cook top burners mentioned, We would suspect a weak, or failing DG94-00520A / DG94-00520A Assy-Hot Surface Igniter. A weak glow bar igniter can cause low temperatures and intermittent operation of the oven. Read More... Answered by AppliancePartsPros.com | Wednesday, May 16, 2018
