Parts for Ge SCA1000HBB04: 03 - Interior Parts (1) Parts

This magnetron thermostat assembly helps prevent magnetron overheating by opening the circuit when temperatures get too high, protecting microwave components and helping restore normal operation once cooled. Fits the OEM thermostat function for safe thermal control. What it does:

• Senses excessive magnetron temperature and interrupts power to prevent overheating
• Helps stop microwave heating when the magnetron runs too hot or thermal limits are exceeded
• Common symptom: microwave powers on but does not heat or intermittently fails to heat
• Restores normal operation after cooling if no other faults are present

• Disconnect power and fully discharge the high-voltage capacitor before servicing
• Replace only with the correct OEM thermostat assembly to ensure proper fit and safety
• Handle with care; avoid shorting contacts or damaging terminal connections

The Switch Monitor Interlock is an OEM replacement part for GE microwaves. This safety component ensures that the microwave operates only when the door is securely closed. It prevents the microwave from running if the door is open, providing a critical safety feature to protect users from exposure to microwave radiation.

Causes of a bad switch monitor interlock can include wear and tear over time, mechanical damage from frequent door opening and closing, or electrical malfunctions that impact its performance.

Symptoms of a bad Switch Monitor Interlock include:

• The microwave not starting or operating intermittently
• The microwave running with the door open
• Error messages or safety warnings displayed on the control panel
• Unusual clicking or buzzing noises when the microwave door is opened or closed

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Door Interlock Switch is an OEM part for GE microwaves. It ensures the safety of the microwave by preventing the appliance from operating while the door is open. This switch is part of a microwave's safety mechanism, which includes multiple interlock systems designed to stop the generation of microwaves immediately once the door is opened, thereby protecting users from exposure to microwave radiation.

Signs that it's time to replace your door interlock switch include the microwave not starting or stopping unexpectedly, the microwave continuing to operate with the door open, or a failure to heat food even though the appliance seems to be running. 

Symptoms of a bad Door Interlock Switch include:

• Microwave does not start
• Microwave stops unexpectedly
• The microwave operates with the door open
• Microwave turns on but does not heat food

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances. 

The Fuse is an OEM part for GE microwaves. It serves as a safety device designed to protect the microwave from excessive current that can cause overheating and potential fire hazards. When the current flowing through the microwave circuit exceeds a certain level, the fuse blows or breaks, cutting off the power to prevent damage or fire.

Common causes for a fuse to blow include power surges, faulty wiring within the appliance, or the use of microwave inappropriate containers that cause sparks. It is essential to address these issues not only to replace the fuse but also to correct the underlying problems to prevent future failures.

Symptoms of a bad fuse include:

• The microwave suddenly stops working.
• No signs of power or response even when the microwave door is closed and the start button is pressed.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Diode Assembly is an OEM part for GE microwaves. It plays a crucial role in converting alternating current (AC) to direct current (DC), which is essential for the microwave’s high-voltage functions, including powering the magnetron to generate microwave energy.

Over time, diodes can fail due to electrical surges, excessive heat, or wear and tear. A faulty diode assembly can lead to inefficient or non-functional microwave operation, impacting its ability to heat food properly.

Symptoms of a bad diode assembly include:

• Microwave not heating food
• Sparking or arcing inside the microwave
• Burning smell or unusual noises during operation
• Microwave turning on but failing to generate heat

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.
