Juan Carlos E Charlotte , NC January 26, 2019 Appliance: General Electric Gas Range ZGU375NSD1SS Ge Cooktop Zgu375nsd1ss: No spark at any burner. How to replace Jet Holder,Main,D,11.7K. I checked the transformer and did not get outlet voltage. The big problem was to release the cooktop cover. The central jet holder broke and was almost impossible to release the cover. In the process was necessary to damage the main tube, the long range nut with chamfer, and the nut. After that I ordered all the pieces to IPS parts because there were 30% cheaper than partspro. IPS people keep saying to me after a lot of arguments that the order will be delivered the next week. After one and a half month I asked for a full refund and cancelled the order. They accept. Immediately I ordered all the parts to parts pro and they delivered all same day!!!. I replaced the transformer and assembled all the damaged parts. Now, everything is working well. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
