Ceramic Line Fuse (20 Amp)
The line fuse is the primary gatekeeper for electrical current entering the appliance. If a surge occurs or an internal component like the magnetron or capacitor shorts, the internal element of this ceramic fuse melts to prevent fire. Once blown, the continuity of the circuit is broken, resulting in a completely dark display and non-responsive buttons.

Thermal Cut-Out (TCO)
This bi-metallic safety switch is designed to open the circuit if the internal temperature of the unit exceeds its rated threshold. In over-the-range installations, excessive heat from the cooktop below can trigger this sensor. If it fails in the 'open' position, power to the control board is permanently interrupted until the part is replaced.

Electronic Control Board
The control board contains a step-down transformer that converts line voltage to low voltage for the logic and display circuits. If the primary windings of this transformer fail or if a solder joint on the PCB cracks due to thermal cycling, the display will remain unpowered even if the appliance is receiving power from the wall outlet.
