Leonard H Gem , KS July 24, 2015 Appliance: General Electric Electric Range JBP78BY5 Ge Range Jbp78by5: Oven would not heat up. How to replace Electronic Control Board. A repairman put his meter on the control panel and said it was going bad but he thought it would last a while longer. It didn't . Instead of calling the repairman to come back out, I ordered the repair part and installed it myself. The new one was slightly different then the one that I took out. The plugs were in different places but with the diagram that came with it I figured out which wire went where. My range has a red wire for the hot wire the diagram said it should be black. It works fine now. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
