Oven wouldn't heat up.

First, I took out the racks from the oven. Next, I took out the black small square cover off the bottom of the stove, which gave me access to the oven ignitor. Then, I removed the screws to be able to take out the ignitor. Finally, I took the bottom drawer out to access the ignitor wire. I pulled the plastic connectors to disconnect the wire. I took the ignitor out and replaced with the new one. I put everything back in reverse order. The oven warmed up about 2 minutes after I turned it on.
