Thermador Transformer

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

This replacement transformer converts household 120V to a 12V control supply to restore low-voltage power for appliance controls and peripherals. It provides a direct, drop-in electrical replacement when the original transformer fails. What it does:

• Steps down mains voltage (120V) to a low-voltage 12V output used by control circuits and relays
• Restores power to control boards, door locks, lights or valves that rely on a 12V feed
• Common symptom: controls or indicator lights are dead while mains power is present
• Common symptom: functions that require the low-voltage supply (locks, dispensers, valves) do not operate

• One transformer (120V primary, 12V secondary)

• Disconnect all power at the breaker or appliance before inspecting or replacing the transformer
• Note wiring locations and secure all connections and strain reliefs
• Mount using existing screw locations or hardware; avoid pinching wires or covering ventilation openings
