Whirlpool Dryer Transformer

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.

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.
