Robert for Model Number GCRG304 You indicated that this part is not compatible for the Thermador GCRG304 spark module which is a Harper Wyman model 6520 which is no longer in business. I ordered this GE WB20X107. it is a perfect match, 110 volts to 4 miliamps, except for the 110 Volt terminals which are smaller on the new spark module. I clipped of the old ones and replace them with new female .100 x .020 leads, 22-18 A.W.G. Works perfectly. Burners light up the same as when they were new.
