Whirlpool Transformer

The Inverter is an OEM replacment part for Whirlpool microwaves. It regulates the magnitude and duration of electromagnetic waves generated during cooking functions.  

Causes of a faulty inverter can include general wear from prolonged use or damage from power surges entering the microwave.

Symptoms include:

• Inconsistent or incomplete heating of foods  
• Sparking or burning smells emanating from within
• Control panel errors or failure to properly sense wattage settings

This OEM Whirlpool replacement ensures precise electromagnetic wave output. Compatible with KitchenAid, Maytag, Jenn-Air, and select other branded microwaves, the inverter restores consistent cooking performance.

This light transformer (20VA) steps down incoming voltage for the appliance's light circuit. Replace a failing transformer to restore dependable illumination so you can monitor cooking progress and see clearly when cleaning.

• Steps down line voltage to the lower voltage used by the light circuit
• Supports consistent, reliable interior lighting
• A failed transformer can leave the light inoperative even with a good bulb
• Intermittent operation or flickering can indicate a weakening transformer

• Disconnect power at the breaker or unplug the unit before servicing
• Access and mounting location vary by model; note wiring and orientation before removal
• Move wires one at a time to the matching terminals/leads on the new transformer
• Secure the transformer and route wiring away from hot or moving parts; test light operation before reassembly

Control transformer that provides stable low-voltage power to the washer's control and user interface, ensuring reliable electrical signaling so cycles start and the machine operates correctly. What it does:

• Supplies the control board and user controls with the required control voltage.
• Restores power to displays, timers, and electronic controls when the transformer has failed.
• Common symptom: machine is dead, display is blank, or cycles won't start.
• Can cause intermittent power or control glitches before full failure.

• Disconnect power before servicing to avoid shock—follow lockout/tagout if required.
• Compare part number and mounting style to the original before installation.
• Handle terminals and wiring carefully; secure all connections and mounting hardware.

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

This control transformer converts household line voltage to the low-voltage feed used by the appliance's control and components, restoring reliable power to timers, relays, and sensors. It's a direct-replacement electrical transformer designed for plug-and-play swap when the original is faulty. What it does:

• Steps down 120VAC line voltage to the appliance's low-voltage control circuit so controls and relays operate correctly.
• Commonly replaces a failed or intermittent transformer that causes control failures, no-power to timers, or unresponsive electronic components.
• Helps restore stable control voltage when the original transformer is noisy, overheats, or delivers inconsistent output.
• Fits the OEM mounting and wiring layout for a clean replacement without modifying existing harnesses.

• One replacement transformer

• Disconnect power at the breaker or unplug the appliance before any service—verify power is off.
• Match wiring colors and terminal positions to the original; secure all connections and use strain reliefs where present.
• Inspect mounting hardware and gaskets; replace any damaged fasteners for a secure fit.
