Jose M Stony Point , NY December 10, 2016 Appliance: Model GE JKP90 Oven would not heat up Had sears Guy come take a look. Told me I needed to change oven control assembly and quoted me over $500. I ordered part myself and saved me some money. Hardest part of the fix was removing display panel to get to assembly. Just take your time. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
