Jvm1190wy003 Parts

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.

This lower door trim replaces the damaged or worn bottom trim on your refrigerator door to restore a finished appearance and proper edge coverage. It matches the original shape and color for a clean, factory look. What it does:

• Covers and protects the lower edge of the refrigerator door from chips, cracks and cosmetic damage
• Restores a consistent, finished appearance to a split or damaged door trim area
• Helps keep the door components and seals properly aligned at the bottom edge
• Useful when trim is cracked, broken, warped or coming loose

• Follow OEM instructions; part installs with existing door screws/clips—do not force
• Remove food and door-mounted items before starting to avoid damage
• Use appropriate hand tools and keep fingers clear of sharp edges
• If sealing or alignment issues remain after trim replacement, inspect door gasket and hinge hardware
