Transformer

Microwave not heating food? The high voltage transformer powers the magnetron. Common when you smell electrical burning or unit stops working.

Microwave not heating or heating poorly? The high voltage transformer powers the magnetron for proper cooking. Direct replacement part for various models.

If your microwave won't heat food or makes humming noises, the high voltage transformer may have failed. Moderate DIY repair for most models.

If your cooktop controls are completely dead or display won't turn on, the transformer may have failed. Restores power to control board circuits.

Microwave not heating? This high voltage transformer powers the magnetron to generate heat. Critical component requiring careful installation.

Microwave not heating? A failed transformer prevents the magnetron from generating heat. This high-voltage component requires electrical expertise to install.

Fix a microwave with no display or unresponsive controls. This control transformer restores low-voltage power to the electronic console when the original fails.

Replace a failed microwave transformer if your microwave won't heat food or runs but produces no heat. Moderate difficulty repair requiring electrical knowledge.

Microwave not heating? This high voltage transformer powers the magnetron to heat food. Common fix for no heat issues in microwaves. DIY-friendly repair.

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.

Fix an air conditioner that won't turn on or has no power to controls with a new transformer. Direct voltage conversion repair for control boards.

Fix an air conditioner that won't turn on or has no power to controls with this transformer. Common repair for units with complete electrical failure.

Fix a hood that won't power on or has no lights with this transformer. This essential electrical component converts voltage to power your range hood.

This high-voltage transformer steps line voltage up to power the magnetron, producing microwave energy. Replacing a failed transformer can restore heating when the oven runs but doesn't heat or hums without cooking.

• Supplies the high voltage the magnetron needs to generate microwave energy
• Failure may present as the microwave running but not heating
• May cause a loud hum or buzz with no heat
• Can blow an internal fuse or trip a breaker immediately after pressing Start

• Disconnect power before service; the high-voltage capacitor can retain a dangerous charge even when unplugged
• Support the heavy transformer during removal/installation and reuse original mounting hardware and wire positions
• After installation, verify secure connections in the high-voltage circuit (capacitor and diode) before testing
