Jvm1850sm1ss Parts

This high-voltage transformer supplies the elevated voltage needed by the magnetron to produce microwave energy. Replacing a faulty transformer restores heating performance and reduces risk of electrical faults in the oven. What it does:

• Converts line voltage to the high voltage required by the magnetron to generate microwaves.
• Can cause no-heat conditions when failed; replaces a transformer that no longer powers the magnetron.
• Works with the HV capacitor and diode as part of the microwave high-voltage circuit.

• Disconnect power at the house breaker and unplug the appliance before servicing.
• The high-voltage capacitor can hold a dangerous charge—discharge it properly before touching HV components.
• Use insulated tools and avoid contact with transformer terminals; refer to the service manual for wiring and mounting details.

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 wire rack assembly provides a sturdy, removable shelf for your oven, giving stable support for cookware and bakeware and restoring proper shelf placement and clearance. What it does

• Replaces a bent, damaged, or missing oven shelf so pots and pans sit level during baking and roasting
• Restores smooth sliding and correct clearance for consistent cooking results
• Helps prevent cookware from tipping or shifting on weakened racks
• Fits into existing rack supports or side rails for secure positioning

• Remove power to the appliance and allow it to cool completely before installing
• Slide the rack into the oven rails or supports until fully seated; it rests level
• Wear gloves to avoid pinches or sharp edges while handling the rack
• No special tools usually required; refer to your owner's manual for model-specific guidance

This upper duct directs exhaust and airflow inside the appliance to help proper ventilation and heat management. It replaces a damaged or warped upper duct to restore correct internal airflow paths. What it does:

• Channels exhaust and internal airflow between the cooktop/vent area and the vent housing
• Restores proper airflow if the original duct is cracked, bent, or blocking ventilation
• Helps reduce unusual smells or cooking smoke reaching cabinetry by maintaining the exhaust path
• Works as a structural guide for adjacent panels and components in the vent area

• Follow the appliance service manual for disassembly steps and correct reinstallation order
• Disconnect power (and gas if applicable) before servicing to avoid shock or injury
• Use appropriate hand tools; avoid overtightening fasteners that can crack the duct or mounting tabs

This rear duct assembly channels exhaust and airflow at the back of the appliance to help maintain proper ventilation and consistent cooking performance. It replaces a damaged or rusted rear duct to restore correct air routing and safety. What it does:

• Directs exhaust and ventilation from the oven cavity to the appliance rear outlet
• Prevents hot air from escaping into adjacent components, reducing heat-related wear
• Helps maintain even temperature distribution and consistent cooking results
• Addresses symptoms like visible duct damage, rattling at the rear, or disrupted exhaust flow

• Intended for rear-panel installation; follow your appliance service manual for exact procedure
• Disconnect power and gas before beginning any repair
• Use correct fasteners and gaskets from the OEM parts list when reinstalling
