General Electric Microwave Transformer

This high-voltage transformer supplies the elevated voltage needed by a microwave's magnetron so the oven can heat food. It replaces a failed HV transformer to restore proper high-voltage output and normal cooking performance. What it does:

• Converts low-voltage input to the high voltage required by the magnetron
• Restores heating when a failed transformer caused little or no microwave output
• Can prevent arcing or unusual noises when damaged or shorted
• Works with the microwave's HV capacitor and diode as part of the high-voltage circuit

• One high-voltage transformer

• Disconnect power and ensure the appliance is unplugged before beginning any service
• The microwave high-voltage capacitor can retain a lethal charge; discharge it first
• Verify correct wiring and secure mounting; reuse or replace any mounting hardware or insulating parts as originally installed

This high-voltage transformer delivers the elevated secondary voltage needed by the appliance's high-voltage subsystem, restoring proper power to that circuit and allowing the unit to operate as designed. What it does:

• Converts incoming low-voltage supply to the high-voltage output used by the appliance's high-voltage circuit
• Restores lost or intermittent high-voltage power that can cause the appliance to stop functioning
• Commonly replaced when the unit shows no high-voltage output, intermittent operation, or when the high-voltage circuit fails
• Matches OEM fit and function to maintain original performance and safety

• One high-voltage transformer

• Disconnect power and follow all safety procedures before servicing; high-voltage components can retain dangerous charge
• Verify and discharge any capacitors per manufacturer instructions before touching the high-voltage circuit
• Use proper tools and replacement wiring/insulation rated for high-voltage service
