• Senses the presence of a gas flame and signals the control to keep the valve open
• Helps prevent gas flow if a flame is not detected
• Can stop ignition or cause the oven/range not to heat when failing
• Commonly replaced when burners won't stay lit or control shows ignition-related errors

• One gas flame sensor

• Turn off electrical power and shut off the gas supply before servicing
• Handle the sensor and its connector carefully to avoid damage
• Reinstall in the exact position and orientation; loose connections can cause false faults

The Monitor Switch is an OEM replacement part for GE microwave ovens. Located internally on the turntable control circuit board, this switch monitors rotation of the turntable during cooking cycles.  

Causes of failure involve degradation of the electrical contacts from continuous arcing loads over years of use combined with vibration stresses.

Symptoms of a faulty monitor switch include:

• The turntable no longer rotates or spinning intermittently
• Cooking cycles aborting prematurely with error messages 
• Screeching or grinding noises emanating from beneath cavity
• Visible burnt spots on turntable drive assembly

This genuine GE switch is also compatible with select Hotpoint and RCA models.

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 Microwave Door Switch is an OEM part for GE microwaves, designed to prevent the microwave from operating when the door is open by interrupting the power whenever the door is not securely closed. The door switch is an essential safety feature.

Symptoms of a failing Microwave Door Switch include:

• The microwave not starting or heating
• Running when the door is opened
• Unusual noises when the door is closed  

Causes of a bad Microwave Door Switch can result from repeated opening and closing of the door or slamming that can cause the switch to degrade or become misaligned, leading to intermittent or failure.

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

This microwave high-voltage capacitor stores and releases energy in the high-voltage circuit to power the magnetron. Replacing a failed capacitor helps restore proper heating and protects other components in the high-voltage system.

• Works with the transformer and high-voltage diode to supply the magnetron with the required voltage
• Failure may result in the unit running but not heating
• Shorted capacitors can blow the internal fuse or trip a breaker; opens may cause loud humming or buzzing
• Visible swelling or leakage on the capacitor body are common failure signs

• Unplug the microwave; capacitors can retain a dangerous charge even when unplugged—discharge using an appropriate, insulated method before servicing
• Note wire positions and terminal orientation; transfer any mounting hardware from the original part
• Mount securely and route wires to avoid pinching

This magnetron assembly generates the microwave energy that heats food. Replace a weak or failed unit to restore proper cooking performance and resolve no-heat complaints when the microwave appears to run but no longer warms items. What it does:

• Converts high-voltage power into microwave energy to heat food inside the oven cavity
• Failure can cause: microwave runs but won't heat or takes much longer to heat
• Often accompanied by a loud humming/buzzing during cook
• May trip the internal fuse/breaker or shut off shortly after start
• Visible damage to the magnetron antenna cap or signs of arcing near the waveguide can point to failure

• 1 magnetron assembly

• Unplug the microwave and safely discharge the high-voltage capacitor before servicing
• Remove the outer cover to access the magnetron; note wire locations and orientation
• Transfer any required mounting hardware/shields from the old part; avoid touching or damaging the ceramic insulators or antenna cap
• Reassemble completely and test heating with a cup of water—never operate the unit empty

• No-heat issues can also be caused by a failed high-voltage diode, capacitor, transformer, or door switches; diagnose where safe before replacing

The High Voltage Diode is an OEM part for GE microwaves. This high-voltage diode is crucial for converting alternating current (AC) to direct current (DC), enabling the magnetron to generate the microwave energy needed for cooking. Measuring approximately 3-1/2" in length, this diode features a banded side with a #8 ring terminal and a non-banded side with a 1/4" female quick connect.

You should replace the diode-H.V assembly if it becomes faulty due to electrical issues, wear and tear, or physical damage. Continuous exposure to high voltage can cause the diode to deteriorate over time, leading to malfunction.

Symptoms of a bad diode-H.V assembly include:

• The microwave not heating food
• A burning smell or unusual noises during operation
• The microwave shutting off unexpectedly
• Visible damage or burn marks on the diode

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