Jvm1740sm1ss Parts

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 stirrer assembly circulates microwave energy inside the cavity so food heats more evenly and prevents cold spots. It replaces a damaged or noisy stirrer that can cause uneven cooking or unusual microwave noise. What it does:

• Spins the microwave stirrer to help distribute microwave energy for more even heating
• Reduces hotspots and cold spots during cooking
• Stops or reduces rattling, grinding, or squealing noises when the original stirrer is worn
• Helps prevent arcing or sparking caused by a cracked or broken stirrer cover

• Disconnect power at the breaker or unplug the appliance before servicing to avoid electrical shock.
• Access may require removing the microwave's outer cabinet or control panel; follow OEM service manual steps.
• Handle the stirrer and cover carefully—plastic parts can crack if forced.

This H.V. transformer supplies the high voltage needed to drive the magnetron in microwave ovens so food heats properly. Replacing a failed transformer restores the high-voltage supply that powers microwave output. What it does:

• Converts incoming low-voltage power to the high-voltage required by the magnetron
• Enables normal heating; a bad transformer can cause no-heat or weak-heat symptoms
• Can produce humming, burning smells, arcing, or tripped fuses when failing
• Works with the high-voltage diode and capacitor as part of the HV circuit

• One H.V. transformer

• Disconnect power and verify the appliance is unplugged before starting
• Discharge the high-voltage capacitor fully to prevent shock; use insulated tools
• Handle the transformer carefully — it is heavy and mounted with screws/brackets

This mounting bracket secures the H.V.C. assembly or cover in place to keep high-voltage components stable and properly aligned. Replacing a damaged or bent bracket restores correct support and reduces movement-related issues. What it does:

• Secures the high-voltage cover/assembly to the appliance chassis to prevent shifting.
• Maintains correct clearance and alignment for high-voltage components.
• Helps reduce noise or arcing caused by a loose cover or bracket.
• Supports safe, reliable operation by keeping wiring and insulating parts in position.

• Disconnect power at the breaker or unplug the appliance before starting work.
• Handle high-voltage components and insulating parts carefully; avoid contact with charged parts.
• Use the OEM part number to fit and orientation before installation.

This air guide bracket secures the refrigerator air guide/duct to keep internal airflow stable and properly directed. Replacing a broken or missing bracket restores smooth airflow and helps maintain even cooling and temperature control. What it does:

• Holds the air guide/duct in place so cold air is directed where needed
• Prevents the guide from shifting, which can cause uneven temperatures or poor cooling
• Supports proper circulation between compartments for consistent performance
• Helps eliminate rattling or vibration from a loose duct or guide

• One air guide bracket

• Always unplug the appliance or shut off power before starting any repair
• Remove shelves, drawers, and trim panels as needed to access the air guide assembly
• Install using the factory screw/clip locations; save and reuse any original fasteners
• Handle plastic parts gently to avoid cracking; test operation after reassembly
