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.

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

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.

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.

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

This lamp ballast is the replacement lighting module that powers and stabilizes the oven/microwave/upper-cabinet light for consistent illumination. Replacing a failed ballast restores a flickering or non-working interior light for safe, visible cooking. What it does:

• Regulates power to the appliance light so the bulb or LED stays on steadily
• Commonly fixes symptoms like a light that flickers, stays dark, or works intermittently
• Works with the appliance's existing lamp socket and wiring harness
• Provides a direct replacement for the original ballast used in compatible units

• One lamp ballast

• Disconnect power to the appliance before starting — turn off breaker or unplug
• Handle gently and avoid bending terminals or damaging the wiring harness
• Reassemble panels and secure mounting fasteners before restoring power

Replacement transformer that restores power to low-voltage components in compatible Broan ventilation appliances, helping lights and control circuits operate correctly. Install the correct PN match to return normal lighting and control function. What it does

• Converts incoming power to the voltage required by low-voltage lights and control circuits in compatible Broan ventilation products.
• Replaces failed or damaged transformers that cause no power, intermittent operation, or flickering lights.
• Stops symptoms such as lights that won't turn on, intermittent lighting, or unresponsive control circuits when the transformer is the fault.
• Fits as a direct replacement when matching the appliance model and part number.

• Always disconnect electrical power at the breaker before inspecting or replacing electrical parts.
• Match wiring colors and connector types; secure all connections and grounding per OEM instructions.
