when i built my wfo, i placed 2 inner and outer thermocouples in each of the hearth, dome, and the walls. much to my dismay when i finally fired up my newly operational wfo, only 2 wires, both, in the dome, gave me an actual temperature readings. the others gave me the same temperature prior to firing. about 79-84 f. the installation seemed straight forward, twist the wires, put in drilled hole, fill with refractory cement, connect to connector with magnetic wire being the negative. any ideas of what went wrong? thanks,
