Original door lock switch for Sauter pyrolytic oven Sauter 8517639

The original sauter 8517639 door lock switch is a critical safety component in built-in & freestanding pyrolytic ovens. The part is manufactured by Eltek in the BC Pyro HF model, and is designed to automatically lock the oven door throughout the pyrolytic cleaning cycle - where the temperature reaches up to 490°C. Only an original part ensures reliable response, resistance to extreme heat, and complete safety.

Pyrolysis not working? Door won’t lock? These are the classic signs of a door switch failure. When the switch doesn’t detect proper closure, the oven’s controller prevents the pyrolysis cycle from starting – a safety mechanism designed to protect you. Click the “Check Model Compatibility” button at the top of the page to make sure the part fits your oven before ordering.

⚠️ Please note: The pyrolytic oven door lock switch is a complex safety component that operates under extreme conditions. Replacement requires partial disassembly of the oven panel and precise electrical connection. It is recommended that the replacement be performed by a qualified technician from the official service.

Why does the door switch break in a built-in & freestanding pyrolytic oven?

The door switch is subjected to extreme heat and cold cycles – unique to pyrolysis ovens. With each cleaning, the temperature rises to 490°C and then gradually drops. Over time, the internal mechanism wears out, the springs lose their elasticity, and the electrical contacts oxidize. The signs: the door does not lock before pyrolysis, pyrolysis does not start, or the lock light flashes and does not go out.

✅ Replacement with an original part ensures a precise mechanism with safe flow up to 16 amps, certified resistance to extreme temperatures, and perfect compatibility with the oven controller.

⚠️ A non-original part may fail within a few cycles under pyrolysis conditions, which can cause a risk of burns if the door is opened during cleaning.

Locating the model sticker on the oven: The sticker with the E-Nr number is usually located on the inner door frame - open the door all the way and check the top or side lip of the frame.

From the experience of our technicians, over 80% of cases where pyrolysis does not start are related to one of two things: the door switch described here, or the temperature sensor. A simple test with a multimeter can confirm the fault before ordering.

🔧 How do you replace a door lock switch in a pyrolytic oven?

Replacing the door switch requires dismantling the back or side panel of the oven, disconnecting electrical connectors, and releasing the assembly from the door mechanism. This is a job that takes 45-90 minutes and requires technical knowledge.

⚠️ Important: Before any work – completely disconnect the oven from the power supply. The switch operates on 230V and an incorrectly connected component may cause an electric shock.

Main replacement steps (for technician):

1. Disconnect the oven from the power supply - check with a multimeter that there is no voltage.
2. Disassemble the upper control panel according to the model's service manual.
3. Locate the door switch – it is usually located in the back corner of the door frame.
4. Take pictures of the electrical connections before disconnecting.
5. Disconnect the connectors, loosen the mounting screws, and remove the old part.
6. Install the new part and reconnect the connections according to the photo.
7. Connect power and check: Close the door and check that the locking mechanism clicks into place.

💡 Tip from the experts

In our technicians’ experience, a large proportion of cases where the door switch is replaced prematurely are caused by greasy dirt that has accumulated around the locking mechanism. A layer of oil baked in during regular cooking cycles hardens the mechanical arm and increases wear. Cleaning the locking mechanism once a year with a damp cloth – without aggressive substances – can extend the life of the switch by years.

❓ Frequently Asked Questions

Why doesn't pyrolysis start in my sauter oven?

When pyrolysis does not start, the controller usually does not receive confirmation that the door is locked. Possible causes: a faulty door switch, a misaligned door magnet, or a fault in the controller itself. First check that the door closes completely. If the light is flashing but pyrolysis does not start – the door switch is probably the cause.

Can I use an oven for regular cooking with a damaged door switch?

Usually yes – normal cooking does not require a door lock, so a faulty door switch will not affect daily functioning. However, pyrolysis will not work. It is recommended not to postpone the replacement, as nearby parts may be damaged by improper mechanical friction.

How long does the pyrolysis process last in sauter ovens?

A full pyrolysis cycle usually lasts two to three hours, including the cooling phase. The door remains locked until the temperature drops below 140°C – the main safety mechanism implemented by the door switch.
