Gerardo I Eagle Pass , TX March 20, 2022 Appliance: General Electric Gas Range CGS990SET1SS Ge Range Cgs990set1ss: Leaking pressure regulator. How to replace Range Top Burner Valve. This is my go-to site to fix the appliances around the house. The pressure regulator behind the stove was leaking and some of the burner valves would not shut off completely. I ordered the parts here and was able to replace the old parts quickly. Now the stove works as it should with no leaks. Thanks, AppliancePartsPros.com!
