De Dietrich Oven Door Switch Replacement: DOP440XE11

ID: 181515

Description: Oven door switch failure. Symptom: The oven...

Steps:

1. Before working on your oven, cut the power at the circuit breaker.
2. To remove the built-in oven from its cabinet, open the oven door, remove the 2 small rubber pieces located on each vertical upright of the oven, and unscrew the 2 screws.
3. Then, extract the oven by using the door and the side handles to help you.

4. Left upright and rubber detail

5. The top metal sheet is held in place by 2 Torx screws, one on the right and one on the left. Unscrew them and slide the sheet toward the back of the oven to remove it.

6. The switch module is located to the right of the power board when facing the oven.
7. BE SURE to note where each wire goes before unplugging the terminals from the module.
8. To remove the module, open the oven door, unscrew the 2 Torx screws, and slide the module slightly toward the back.

9. This is where the difficulty begins, as the manufacturer modified the new part (The part number of the genuine part and that of the replacement part are nonetheless identical...)
10. The genuine part had terminals, while the replacement part has a specific connector. It is therefore not possible to reconnect the wires to the new part without purchasing a small piece of special cable or by performing an adaptation that requires some soldering.
11. The contacts, instead of being independent (terminals), have been grouped onto a printed circuit board. The part has also been significantly improved, as we note the presence of 2 micro-switches replacing the standard mechanical contactors.

12. Unclip the module cover with a small flathead screwdriver. Do not force it too much to avoid breaking the plastic tabs.
13. Remove the printed circuit board and desolder the 2 white wires going to the electromagnet (later, you will reconnect the terminals coming from the power board directly to the electromagnet).
14. For each contact (Lock Contact, Door Contact, Common Phase), solder a piece of rigid electrical wire ending in a male terminal (automotive type) onto the printed circuit board.
15. The schematics shown opposite will help you when reconnecting the terminals.

16. To reassemble the module, it is important to have the oven door open (to avoid putting force on the plastic door detection latch).
17. Properly reconnect all wires coming from the power board to the module terminals.
18. The wire that previously connected terminals B to C on the original module is no longer necessary; you can cut it.

19. For reference and to assist you with reconnection to the new module.

20. Securing the control panel that tends to slide backward when you press the buttons on the front, making button presses ineffective or difficult.
21. In my case, part of the plastic support that holds the circuit board was broken.
22. Use plastic zip ties to prevent the circuit board from sliding backward.
