It was an easy fix. I first pulled out the oven to shut the gas supply valve and disconnect the electrical cord. I was able to access the safety valve by removing the bottom warmer drawer. After that it was just a matter of disconnecting the old valve and replacing it with the new one. The only tools needed were a 1/4" nut driver and a 9/16" open end wrench. The amazing thing was how fast the new valve arrived. I ordered it on a Friday afternoon with regular shipping and it arrived the very next day. Wow, that's fast! It was also the cheapest price I found. Great experiance and will definately be a repeat customer in the future.
