Oven TEKA HM 835 - If you bypass the clock, you will not go to the oven

Hello,

At the beginning I am asking for your understanding if you think that the topic has already been raised. Yes, I searched the forum, but I didn't find any information about my model.

I have an oven from TEKA

model HM-835.1
type: 7NB01Q111
serial number: 1214009230100026

For some time there is a problem with setting the clock after turning the power off and on. Unfortunately, this is often the case at my location.
The keys in the control panel do not work, no reaction. The keys can be removed and I tried directly with a thin screwdriver to set it up, but also without effect.
To set the clock, simultaneously press the two extreme buttons from the left and + or - respectively.

According to the TEKA authorized service, the reason is a broken clock, but this is a part that is already unavailable and the topic lost. In the central service they also confirmed this.
In this case, there is no classic thermostat, only the oven has a temperature sensor installed and everything goes through the "main" plate to the temperature control potentiometer.

Hence my question for help is going somehow around the clock. I searched the forum a bit and sometimes you have your proven repair patents.
The question is, maybe someone has already developed this particular model ??

Maybe someone will recommend some proven good home appliances service in the vicinity of Poznań, Szamotuł, Obornik Wlkp. One service has already looked at it but gave up.

If you need pictures of wire connections, we will do and attach.
Many thanks in advance for your help and feedback.
Best regards,
Darek

Whether the function switch and the thermostat in this oven are mechanical or electronic. If mechanical, it can be done.

Hello,

Yes, the function switch and thermostat are electronic. Everything goes through the "motherboard" with the clock.
Wires from the function switch through a 4-pin connector are connected to the motherboard (here at least there is normal access to the cables).
On the other hand, on the other side of the board comes a tape (similar to solutions from a computer) and enters the thermostat through 2 wires.
The best way I can add photos of the layout.

Best regards,
Darek

Like most cookers without a clock setting, the oven does not work because it is powered by a relay. It would be necessary to short-circuit its contacts by permanently soldering the jumper.

Remur, have you already done such a transformation and are you far to Poznan ???
Thanks for the reply and the link

Greetings.

Hello
Unfortunately, there is no way around the programmer in this oven. Everything is controlled by the temperature module, heaters, etc.

Yes, the thermostat, but after the number of leads from the control panel, I dare say that the function switch (left side) is a mechanical switch, which confirms link .
AND here but I was close .
And some more interesting solutions

After bridging one relay, you can turn on the fan and the light, and by bridging both, you can turn on the heaters, but without the thermostat of course

It was necessary to check which relay is responsible for turning the heaters on, and connect the wires connected to it with a mechanical thermostat, which can be installed in the place of the thermoregulator potentiometer.

Hello

Can the way with relays to make permanent contacts through a jumper solve the topic or not ???
pzdr.

I suggest only practical solutions, and the rest is up to you. If you don't check it, you won't find out.

OK thanks Remur. If I succeed, of course I will let you know.
