Parts for Thermador SMW272W: 02 - Top Plenum Control Parts

This transformer provides the low-voltage power supply required by the appliance control system, enabling proper operation of the control board and related low-voltage circuits. Replaces a failed or noisy transformer to restore reliable control power. What it does:

• Steps down mains voltage to the appliance's low-voltage control circuit for the control board and relays
• Helps restore control functions when a failed transformer causes no power, intermittent control operation, or unresponsive electronics
• Prevents control-board brownouts by providing consistent low-voltage feed (when the transformer itself is the issue)
• Used wherever a dedicated appliance control transformer is required by the appliance's electrical system

• One replacement transformer

• Always disconnect power to the appliance before accessing electrical components
• Verify wiring locations and terminal IDs before removing the old transformer; label wires if needed
• Transfer mounting hardware and brackets from the old part unless new hardware is explicitly included

Single oven. Includes display board, relay board, wire harness and instructions. For the double oven display kit order 00702451.

This replacement tension spring restores proper tension and smooth movement for the affected appliance mechanism. It helps bring parts back into correct alignment and reduces loose or inconsistent operation when the original spring fails. What it does:

• Provides restoring tension for the associated moving part to maintain correct position and motion
• Helps eliminate loose, sagging, or unstable movement caused by a worn or broken spring
• Reduces rattling or intermittent operation related to a failed spring
• Works with the appliance's pivot or latch assembly to ensure reliable engagement

• Disconnect power to the appliance before beginning any repair to avoid shock or injury
• Springs are under tension; wear eye protection and use appropriate tools to control tension during removal and installation
• Note orientation and attachment points of the old spring for correct reinstallation

This wiring harness connects the oven door latch and self-clean lock mechanism to the oven's control system, restoring electrical connection for the door locking function during self-clean cycles. Use when the door lock won't engage or the lock switch has no power. What it does:

• Routes electrical signals between the oven control and the door latch/lock assembly
• Enables the door to receive lock/unlock commands during self-clean cycles
• Commonly replaced when the door won't lock, the lock motor doesn't respond, or self-clean won't start
• Helps clear failures caused by broken, burned, or disconnected latch wiring

• One oven door latch/self-clean wiring harness

• Disconnect power to the appliance before beginning any repair
• Access may require removing the oven door or inner panels; follow OEM disassembly steps
• Match connector shapes and wire routing; secure harness to prevent pinching or heat exposure
• Test door locking operation and self-clean function after installation
