General Electric Microwave Transformer

Microwave not heating or making loud buzzing sounds? The high-voltage transformer powers the magnetron. Requires caution when testing or replacing.

Microwave runs but won't heat food? This high-voltage transformer powers the magnetron to generate heat. Restores cooking function when failed.

Microwave not heating? A failed high voltage transformer prevents the magnetron from producing microwave energy. DIY repair restores heating function.

Fix a microwave that stopped heating or made a loud noise. This high voltage transformer powers the magnetron. Moderate DIY repair for experienced users.

Fix a microwave that won't heat with this high voltage transformer. Powers the magnetron tube to generate cooking heat. Technical repair for experienced DIYers.

Microwave not heating? A failed high voltage transformer disrupts the voltage supply needed for heating. This repair requires electrical knowledge.

This high-voltage transformer supplies the ignition voltage used to create sparks for gas burner/oven ignition. Replaces a worn or failed transformer to restore reliable spark firing and consistent burner ignition. What it does:

• Converts line voltage to the high-voltage pulse needed for spark ignition
• Sends ignition sparks to surface burners or oven igniters so gas will light
• Common symptom: clicking with no visible spark at the burner or burner(s) that fail to ignite
• Other symptom: intermittent ignition or weak sparking

• One high-voltage transformer

• Disconnect power to the appliance before servicing to avoid electrical shock
• Handle the transformer and high-voltage leads with care; do not operate with covers removed
• Verify correct diagnosis before replacing; check ignition module, wiring, and spark electrodes for faults

Microwave not heating food? This high voltage transformer powers the magnetron to generate heat. Moderate DIY repair restores cooking performance.

Fix a microwave that won't heat or has no power with this low voltage transformer. Common repair for dead displays and control panel issues.

Microwave not heating food? The high voltage transformer powers the magnetron. Common failure part when microwave runs but won't heat properly.

If your microwave won't heat food or runs but doesn't warm, the high voltage transformer may have failed. This power component is essential for operation.
