This is a small synchronous motor used in microwave ovens to drive components such as the turntable or air damper. It operates at a steady rotational speed to ensure consistent movement during cooking. Replace this motor if the turntable stops spinning, rotates intermittently, or if you hear a humming noise without any movement.

This humidity sensor detects moisture levels inside the microwave cavity during cooking, allowing the control board to automatically adjust cook time and power. It is typically mounted inside the cooking compartment or vent area. Replace this sensor if your microwave's auto-cook or sensor-cook modes no longer work correctly, food is consistently overcooked or undercooked, or the unit displays a sensor error code.

Fix a microwave that won't start or has no function with this main control board. Restores operation when buttons don't respond or display fails.

Fixes weak ventilation, excessive noise, or overheating in your microwave. This blower wheel restores proper airflow to clear steam and cool components.

This is the support ring assembly that sits on the microwave floor and holds the glass turntable tray in place while it rotates during cooking. It typically features small wheels or rollers that allow the tray to spin smoothly. Replace this ring if the turntable wobbles, does not rotate evenly, or if the rollers are cracked or missing.

Replace a cracked, stripped, or missing control knob on your microwave. This knob installs on the control shaft for secure, accurate setting selection.

This AC fan motor drives the cooling fan inside a microwave or combination cooking unit, circulating air to prevent internal components from overheating during operation. It helps protect the magnetron, control board, and other electronics by dissipating heat. If your microwave overheats frequently, shuts off mid-cycle, or you no longer hear the cooling fan running, this motor likely needs replacement.

Secures microwave components to their mounting points. Replace this nut assembly if damaged, missing, or worn to prevent rattling and keep parts aligned.

Truss-head self-tapping screw for securing microwave panels, trim, and brackets. Replace lost or damaged mounting screws to restore fit.

Self-tapping pan-head screw secures interior panels, vent grills, and brackets in microwaves. Replace missing, stripped, or lost screws during repairs.

Replacement mounting bracket that secures internal panels to the frame. Install this bracket if your original is cracked, bent, or missing.

Truss head tapping screw for microwave assembly. Secures internal components and panels. Replace if screw is stripped, missing, or lost during repair.

This heater sheath is the protective metal sleeve that surrounds a dryer/oven heating element, helping protect the element and focus heat where needed for reliable appliance heating performance. What it does:

• Protects and supports the heating element inside the appliance
• Helps direct and contain heat for efficient operation
• Can prevent direct contact between the element and surrounding components
• Commonly replaced when the sheath is corroded, dented, or damaged
• Linked to uneven heating or visible element damage

• High-level replacement only; disconnect power before servicing to avoid shock hazard
• Inspect surrounding components (element, terminals, mounting clips) and replace any damaged parts
• Use proper fasteners and ensure sheath is seated securely to avoid contact with other components

Replace your broken or cracked microwave vent grille. This cover installs at the top to safely vent heated air and moisture during operation.

Microwave won't start or door won't stay closed? A worn door latch spring prevents secure latching. DIY repair typically takes 20-30 minutes.

Fix a microwave not heating, vent fan not working, or lights that won't turn on. This relay board controls power, heating, and safety circuits.
