/6 running cool !?

defective t-stat? Was it running too cool before the 190 t-stat. Did yout check the 190 t-stat on stove before you installed it? a quick temporary fix block off some of the rad with cardboard. Ambient temp has been unusually cool for the PNW.
I did the cardboard block. No I didnt check it in the oven. I will do that to the next one.
