Parts for Ge JVM1190AY004: 02 - Case & Interior Parts

Fix a microwave that won't heat or makes loud humming noises. This high voltage capacitor often fails when the magnetron can't generate heat properly.

Microwave not heating but lights and timer work? The high voltage diode converts AC to DC for the magnetron. DIY repair in 1-2 hours with basic tools.

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

Protective cover guard for your microwave's interior oven lamp. Replace this part if the original cover is cracked, broken, or missing to protect the bulb.

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

Fix sensor cook cycles that won't adjust properly or show sensor errors. This humidity sensor monitors moisture levels for automatic cooking adjustments.

This thermal fuse is a safety device designed to cut off power to the microwave if internal temperatures exceed safe limits. It is a small, inline fuse typically mounted near the magnetron or cavity. Replace this part if the microwave has completely stopped working with no display or response, especially after an overheating event.

Gray bottom plate for microwave interior base. Replaces cracked, warped, or discolored plates. Installs on cavity floor for structural support.

Grease filter for range hoods and over-the-range microwaves. Dimensions: 6-3/8" x 9-9/16" x 3/32" (6.375 x 9.5625 x 0.09375). Rectangle shape. Captures grease from cooking air. Replace when clogged, discolored, or every 6-12 months.

Illuminates your microwave interior for monitoring food during cooking. Replace when bulb burns out or dims. Verify fit with your model number before ordering.

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
