Parts for Ge JVM190K02: 02 - Section2 Parts

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.

A replacement magnetron duct that directs microwave energy and helps protect internal components in countertop and over-the-range microwaves. Restores correct waveguide alignment and helps maintain heating performance when the old duct is damaged. What it does:

• Channels microwaves from the magnetron to the oven cavity while shielding surrounding components.
• Protects the magnetron and high-voltage area from debris and arcing.
• Commonly replaced when cracked, warped, or showing burn marks that can affect heating.
• Helps reduce unusual noises or sparking coming from the microwave cavity area.

• Disconnect power and discharge high-voltage capacitors before accessing the magnetron.
• Wear gloves and eye protection; sharp sheet-metal edges may be present.
• Secure mounting screws to prevent gaps that can cause arcing.
• Do not operate the microwave with covers or ducts missing or improperly installed.

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

This is a magnetron that is used on microwave ovens. The purpose of the magnetron is to provide the microwaves that actually cook the foot inside of the microwave oven. Use caution when replacing this part. High-voltage capacitors in microwaves can retain a deadly amount of electrical charge, even when they are unplugged.If the microwave begins making a buzzing noise and doesn't heat food properly, this part will need to be replaced. Use extreme caution when working with this appliance. Unplug the unit first.This particular magnetron is compatible with microwave ovens that are manufactured by the General Electric, Hotpoint, and Maytag brands. This part is sold individually and is sourced directly from the manufacturer as a genuine OEM part.

This high-voltage transformer supplies the ignition voltage used to create sparks for gas burner/oven ignition. Replaces a worn or failed transformer to restore reliable spark firing and consistent burner ignition. What it does:

• Converts line voltage to the high-voltage pulse needed for spark ignition
• Sends ignition sparks to surface burners or oven igniters so gas will light
• Common symptom: clicking with no visible spark at the burner or burner(s) that fail to ignite
• Other symptom: intermittent ignition or weak sparking

• One high-voltage transformer

• Disconnect power to the appliance before servicing to avoid electrical shock
• Handle the transformer and high-voltage leads with care; do not operate with covers removed
• Verify correct diagnosis before replacing; check ignition module, wiring, and spark electrodes for faults

This high-voltage rectifier diode is used in the microwave's high-voltage circuit. It converts AC to DC so the magnetron can produce heat. A failed diode can cause no heat, loud humming, or a blown fuse when starting. What it does:

• Rectifies high-voltage AC to DC to power the magnetron
• Blocks reverse voltage in the HV circuit
• Common failure symptoms can include: runs but doesn't heat; loud hum then shutdown; line fuse blows at startup

• 1 high-voltage diode

• Unplug the microwave and properly discharge the high-voltage capacitor before servicing—dangerous voltage can remain even when unplugged
• Match diode orientation/polarity to the original and ensure a solid chassis ground connection where used
• Route leads and reinstall any clamps/insulators exactly as found; keep wiring clear of sharp edges and hot components
• If the original diode failed, inspect the HV capacitor and transformer for related issues before reassembly

This microwave thermostat is a temperature-sensitive safety switch that helps protect the unit from overheating. When the preset limit is reached, it interrupts power to the affected circuit to help prevent damage and erratic shutdowns.

• Monitors temperature at its mounting location and opens the circuit if overheating is detected
• Helps protect internal components from excessive heat
• Common symptoms of a failed thermostat include: unit shuts off during cooking, won't start until it cools down, or has no power/no heat due to an open safety
• Replace if the original tests open when it should be closed

• Disconnect power by unplugging the unit or switching off the circuit breaker before servicing
• Microwaves contain a high-voltage capacitor that can retain a dangerous charge; only qualified persons should service and discharge the capacitor
• Note wire locations before removal and transfer connections firmly to the new thermostat
• Mount the thermostat securely and in the same position to ensure proper temperature sensing

This small spacer positions and stabilizes the oven rack inside the cavity. Replacing a worn or missing spacer restores correct rack height and alignment so the rack slides smoothly without scraping or wobbling during use.

• Maintains proper clearance between the rack and oven wall/rail
• Keeps the rack level and correctly aligned on its supports
• Helps the rack slide in and out smoothly
• Direct replacement for a cracked, deformed, or missing spacer

• Disconnect power; if gas, shut off gas supply. Allow the oven to cool completely.
• Remove the rack and note the spacer's original location and orientation.
• Install the spacer in the designated position and ensure it is fully seated.
• Reinstall the rack and ensure smooth movement and secure support.

Ceramic

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

This replacement sensor receptacle connects the refrigerator sensor to the appliance wiring harness so the control can read accurate temperature signals and maintain proper cooling performance. What it does:

• Provides a secure electrical connection for the temperature/evaporator sensor to the main wiring harness
• Restores reliable sensor signaling so the control can make correct temperature decisions
• Can help address intermittent temperature readings, unexpected defrost cycles, or control error codes related to sensor communication
• Replaces a damaged, corroded, or loose receptacle that causes poor connectivity

• Disconnect power to the appliance before starting any repair
• Verify the connector orientation and secure fit; do not force pins or terminals
• Inspect mating harness and sensor for damage; replace any worn wiring or terminals

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
