REGULATOR 318122721

First, I watched a lot of videos on YouTube. All of them were very similar, and had similar repair instructions, doing all the work at the site of the regulator location. The gas supply flex line was easily detached, as well as the line that exited the regulator to feed the stove. The gas inlet nipple, however, was not willing to unscrew. My regulator was held on by Phillips head sheet metal screws, which were easy enough to unscrew, so I just removed the regulator, still attached to the gas connection nipple. I went to my shop and placed the regulator in a vise, careful to clamp either end, not the regulator valve itself, and used a deep socket over the nipple, and had to use a Breaker Bar to loosen the nipple. I cleaned the nipple where Pipe Dope had been used, and applied new sealant, then screwed it back on the the Regulator, once again using the socket and bar. Then I threaded the new regulator body with the sheet metal screws while it was clamped in the vise. (The new regulator was not threaded, and I had to use vise grips to hold the screws while turning them in) After that, installation of the new regulator was relatively easy. I wish Frigidaire had used hex head screws instead of the Phillips. After install, range worked perfectly. PartSelect delivered correct part in a timely manner.
