Oven would not heat/could smell the gas

He took out the bottom of the oven floor...came out easy ..had to unplug the old part and installed the new one the same way.He did have to unscrew two pieces. The only difficult part was reaching to plug in. Not too bad. Now he could do it quick and easier. Problably 10 minutes the most. Stove works great and I can cook again. Makes me happy.Thanks for all your help.
