is there a way to make a redstone powered furnace?

im making a industrialcraft inspired mod, and i want a furnace that is powered by redstone. after so many checks and debug markers, and some cheeky chat gpt checks, ive got nothing. i dont know what part of the block isnt working, because there is: the block, the gui, the redstone on procedure, and the tick update procedure. i will attatch the procedures just incase they are at fault. many thanks!
