Kaltstartventil

It occurs to me that the same problem can be for cables from other things, after all, you mentioned somewhere that a small current flows through the sensors and the cold joints win and trouble us. All it takes is dirt, grease, a rotten cable under the insulation (you know, you take off the insulation and the cable is green, rotten to powder, you can't tell from the outside) and problems abound. And it turns out that measuring by beeping won't help.

Hi,

And yes picture shows a later thermottime switch as installed in 107 and 116. They were often installed as replacement of the old versions with screws. You need one with the data I mentioned above.
