Robert B Murphy , TX October 13, 2019 Appliance: General Electric Electric Range JTP56SD1SS Ge Oven Jtp56sd1ss: Needed new grates. How to replace Bottom False Assembly (Lower Interior Trim). Bought new ones from AppliancePartPros. These are like the originals. I realized the oven was missing the False Bottom when looking at the assembly drawings on the website. With that assembly, the oven looks newer than ever. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
