Parts for Lg LTM9000W: Oven Interior Parts (Ii) Parts

A high-voltage capacitor for the appliance's high-voltage circuit that stores and releases electrical energy to support proper heating operation. Replacing a failing capacitor can restore consistent heating and prevent related electrical faults. What it does:

• Stores and delivers high-voltage energy used by the magnetron/ high-voltage assembly to generate heat.
• Failure may cause no-heat or weak-heat conditions in the oven.
• Faulty capacitors can contribute to arcing, loud humming, or blown high-voltage fuses.
• Works as part of the HV circuit; not a user-serviceable low-voltage control.

• High-voltage components can hold a dangerous charge—disconnect power and discharge the capacitor before servicing.
• Use insulated tools and avoid touching terminals; verify proper operation with appropriate test equipment.

This magnetron is the high-voltage microwave tube that generates the microwave energy used to cook and reheat food in your oven. Replacing a failing magnetron restores heating performance when the rest of the microwave system is functioning. What it does:

• Generates microwave energy that heats food inside the oven cavity
• Common symptom: unit powers on but does not heat
• May also cause loud humming, burning smell, or arcing when failing
• Works with the oven's high-voltage circuit and waveguide to deliver even cooking

• One magnetron

• High-voltage component — disconnect power and discharge the capacitor before service
• Avoid touching terminals or the ceramic insulators; handle by mounting brackets
• Verify other high-voltage components (diode, capacitor, transformer) and seals to ensure safe operation
