display would not light and oven would not work all the time

First I turned the power off to the stove at the breaker box. I opened the oven door and took off the four hex head screws holding the face panel on. There are four philips screws holding a trim piece on the panel that does not need to be removed and the two end caps do not need to be removed either. I pulled the panel out and tipped it up so I could access the clock display unit. There are two wiring harness clips that unplugged very easily. The ribbon connector is a little more tricky. You have to slide up two clips on the end and then slide up a section going across the ribbon. It's very easy, just don't try to pull the ribbon out without undoing the clips. The display unit was held on with two hex head screws. I removed them, attatched the new one and put it back together. I then turned the oven back on to see if it worked. The display worked perfectly but, the oven would still not get hot on bake. I turned the breaker off again and removed the shelves in the oven. I then removed the two phillips screws holding the bottom bake burner in and pulled it out until I could access the clips. I pulled off the clips and checked the burner for continuity. There was none so I ordered a new bake burner. The new burner showed up the next day and I hooked it up in about 5 minutes. The oven works great and I couldn't be happier with the experience I had with partselect.com
