At last I found the problem. I'm really thankful, member ''bmw530d'' for the 236th message. Even if my pcb microscheme looks really pretty, taking off the kondensator I found a corrosion hearth under it which destroyed the transition path.

The problem was in this BTS 141, not that Resistor 2002 20kOm

Hello.
I have found this thread by searching for a fix on my Webasto Thermo Top C. It looks like my PCB is a bit different than yours, i think thats because the one i have is rather new (2014-2015).
The problem i have is, that the heater always reads a resistance of 1.4 ohm from the flame sensor. I have measured the flamesensor with a multimeter and it is within spec (0.2-0.3 ohm). I have also tried another flamesensor, but without luck.
At first i could get the heater to work by applying contact cleaner to the pins on the PCB. But that only works temporably and i dont think thats was because of the contact cleaner.
I have tried to measure all of the resistors on the PCB and it looks like all are within spec.

Does any of you have experience with this problem?
Thanks.

Yours is Thermo Top E

Hello.
Why do you think it is a thermo top e?
I am pretty sure it is a c model because it can controle the water pump and there is written thermo top c on the burner house :-)

Did you succeed in solving the problem?

and what motor is it from

Hello. I think its a aftermarket unit. In the webasto software i use the "Fiat" version to acces it, i dont know why. I still wont work. I have bought a used replacement motherboard

Hello Arminas.
I have measured those two resistors. They look fine, but I will try replacing them anyway. Do you have any experience with those two om that board?
Thanks.
