Hi, I have a 5000 Cal Orma Calorama stove. A while ago I was humping and it was hard to light the pilot, it was not on but insisting it came on. Today I could not turn it on since the pilot turns on, I am having a good time keeping the knob tight to make the thermocouple hot and thus be able to give it a minimum or maximum according to the need but it is no longer on. Surely it is the thermocouple, isn't it ??????? You should loosen the nuts of this rod on both sides, remove it and go to a store with the sample to replace it. Or is it possible that it is another subject? If I am not mistaken in one end of the rod, the iron is heated and in the other the electromagnetic valve (or something similar). I have to change all this, right ???? Thank you in advance for your help.
