Temperature Sensor (RTD)
The RTD sensor uses a platinum film resistor that changes resistance based on temperature. If the internal resistor drifts out of calibration due to thermal stress, it sends an incorrect signal to the control board, causing the oven to 'think' it has reached the setpoint when it is actually 50-100 degrees lower. Replacing this component restores the accuracy of the feedback loop.

Hidden Bake Element
The hidden bake element provides the majority of the thermal energy for standard baking cycles. If the internal filament fractures, the oven will attempt to preheat using only the broil and convection elements, which is significantly less efficient and often fails to reach the set temperature. A new element ensures the primary heat source is operational.

Power Relay Control Board
The relay board contains the mechanical switches that route 240V power to the heating elements. Over time, these relays can suffer from contact pitting or carbon buildup, leading to intermittent power delivery. If the relays fail to stay closed during the heating phase, the oven will struggle to maintain its temperature even if the sensor and elements are functional.
