Jenn-Air Microwave Capacitor

This magnetron capacitor is the microwave high-voltage capacitor that helps supply the magnetron with the pulse of energy needed to produce heat. Replacing a failing capacitor restores normal heating performance and reduces arcing or loud humming. What it does

• Stores and releases the high-voltage pulse required by the magnetron so the microwave can generate heat.
• Prevents unstable magnetron operation that can cause weak or no heating.
• Common symptoms of a failing capacitor: oven runs but doesn't heat, intermittent heating, loud buzzing/humming, or visible arcing inside the cavity.
• A failed capacitor can also cause blown internal fuses or tripped circuits.

• One capacitor.

• Disconnect power and verify the appliance is completely de-energized before servicing.
• Capacitors can hold dangerous charge; discharge the capacitor safely with an insulated tool.
• Use the exact replacement part and follow the appliance service manual for routing and connections.

This high-voltage magnetron capacitor stores and delivers the pulse of energy the microwave magnetron needs to generate heat. Replacing a failed unit restores proper high-voltage function so the oven can heat reliably. What it does:

• Stores and releases high-voltage energy to the magnetron during cooking cycles.
• Works with the oven's diode and transformer to produce microwave energy.
• A failed capacitor can cause no heat, weak heating, or a blown fuse/circuit interruption.
• Designed for the microwave high-voltage assembly; handle as a high-voltage component.

• Disconnect power and unplug the appliance before service.
• Discharge the capacitor with an insulated tool before touching terminals.
• Verify this part number matches your appliance before ordering.
