The E1 code isn't just a glitch; it is a critical internal sensor failure.
The E1 code signals that your oven’s internal thermal sensor, the NTC thermistor, has failed.
Constant exposure to heat, steam, and acidic grease degrades the sensor's protective coating over time.
Resetting only masks the decay; it forces the board to accept faulty data temporarily.
Once the thermistor resistance drifts out of range, the hardware requires professional repair or replacement.
