Parts for Ge JVM1190CB002: 02 - Case & Interior Parts

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.

This 250V 15A safety fuse protects the appliance's line circuit from overcurrent. When the original fuse has blown, replacing it can restore power and help safeguard internal components from further damage.

• Opens the circuit if excessive current or a short occurs, protecting internal parts
• Common symptom: unit completely dead—no display, lights, or response to controls
• Blown fuse will test open (no continuity) with a multimeter
• If a new fuse blows again, another component may be shorted and needs diagnosis

• Unplug the appliance before servicing; microwaves can retain a dangerous charge—discharge the high-voltage capacitor
• Access the fuse near the line filter/control area; note clip orientation
• Replace only with the same 250V 15A rating; never bypass or upsize the fuse
• If the replacement fuse blows immediately, stop and troubleshoot the root cause

This upper duct directs airflow inside the appliance to help vent steam and cooking vapors away from internal components. It replaces a damaged or warped duct to restore proper airflow routing and reduce moisture buildup. What it does:

• Channels exhaust and airflow through the appliance cabinet for proper venting
• Prevents contact between internal components and redirected steam or grease
• Helps reduce moisture accumulation that can lead to odors or component corrosion
• Fits into the upper duct assembly location to maintain designed airflow paths

• One upper duct (upper B) as shown

• Disconnect power to the appliance before beginning any service
• Handle the duct carefully to avoid bending or cracking mounting tabs during installation
• Verify alignment with adjacent duct pieces and secure all fasteners; test airflow operation after reassembly

This gas sensor monitors moisture levels during sensor-cook cycles so the control can adjust time and power for consistent results. Replacing a failed sensor restores reliable sensor-cook performance. What it does:

• Detects steam/vapor inside the cavity and sends feedback to the control board
• Helps the appliance automatically set or adjust cooking time on sensor settings
• Failure symptoms can include sensor-cook not starting, stopping early, or running too long
• May trigger "Sensor" or general error messages related to sensor-cook functions

• Disconnect power before servicing; if working on a microwave, discharge the high-voltage capacitor
• Access is typically behind the control panel or air channel; avoid touching/contaminating the sensing surface
• Transfer any mounting clips/brackets and ensure the wiring connector is fully seated
• After installation, run a simple sensor-cook test to confirm operation

This thermostat is a temperature-sensing safety switch used in microwave ovens. It monitors heat and opens the circuit during an over-temperature condition to protect internal components and help prevent damage. What it does:

• Monitors temperature at a specific location inside the microwave
• Interrupts power if overheating is detected to protect components
• Helps safeguard the magnetron and wiring from thermal damage
• Presents as: shuts off mid-cycle, won't restart until cooled, no power, or runs but doesn't heat

• 1 thermostat

• Disconnect power before service; microwaves contain a high-voltage capacitor that can hold a dangerous charge—discharge it properly
• Note wire locations and transfer connections one at a time to the new thermostat
• Mount in the original location with firm, flush contact to the surface for accurate sensing
• Reinstall all covers and safety shields before restoring power and testing

Color: metallic. Measures about 6 inches wide by 9-1/2 inches deep.

The Light Bulb is an OEM part for GE microwaves. This bulb illuminates the interior of the microwave during operation, enhancing visibility so you can monitor the cooking process without opening the door. It is designed to withstand the high temperatures and vibrations typically found in microwave ovens.

Over time, the light bulb can burn out or become damaged due to the harsh environment of the microwave. Frequent on and off cycles can also shorten the lifespan of the bulb. Replacing a non-functioning or dim bulb will restore visibility and improve the functionality of your microwave.

Symptoms of a bad light bulb include:

• Dim lighting inside the microwave.
•  Flickering or inconsistent performance.
• Complete lack of light when the microwave is operating.

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

This run capacitor helps the appliance motor start and run smoothly by storing and releasing electrical energy. Replacing a worn capacitor can restore reliable motor operation and reduce abnormal motor noise or cycling. What it does:

• Provides the brief power boost motors need to start and maintain RPM
• Helps stabilize motor voltage and improve run efficiency under load
• Commonly linked to symptoms such as motors that hum but won't start, slow or intermittent motor operation, or unusual motor noise
• Reduces stress on motor windings that can lead to premature failure when functioning properly

• One motor capacitor

• Always disconnect power at the breaker or unplug the appliance before servicing
• Capacitors can hold a charge; discharge safely
• Observe proper polarity and mounting location during installation; secure wiring and connectors
