Hi Team, I purchased an old Cress B-1411 with 2x Thrumwheels and a kiln sitter. I went to bisque fire to cone 04 and after 14 hours and fully cranked it did not hit temp. I cranked the bottom thumb wheel, and see the indicator light on, and see the bottom coil become red hot. I also here the relay pulsing. When I crank the top thumb wheel the indicator light comes on but none of the coils become hot. I had an electrician friend come by and check the pulses. The top relay does not produce much of any output. I do not see any visual breaks in the coils. My first question is, based on these observations, can I accept that the top relay needs to be replaced? Why is only the bottom most coil getting hot vs. the bottom 2 or 3 (6 rows total)? Ideally this kiln automatically increases its temperature vs. a thumb wheel. If I am going to have to replace one of these relays I would rather replace it with an automatic firing relay that has firing speeds. Is this an easy change or is adding a dial that has a firing speed complex and pricey? Any information / help would he great. Also, if you could let me know the best product to replace the broken pieces that would be amazing. Thanks, Jesse
