Melanie S Haymarket , VA October 05, 2014 Appliance: Model JKP77G0J1 The old element had a crack and eventually was taking 30 40 minutes to pre heat We quickly found the part on Appliance Parts Pro for our oven build in 1982! We replaced the element in just 10 minutes and now the oven preheats like it's brand new. It was an easy fix to what we felt might end up as a whole new oven. Thanks for saving us hundreds of dollars! 7 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
