Product review (4 stars): fixed oven
had oven wouldnt light.  I replace "hot source ignitor" AND this gas valve / safety valve and it fixed oven.  Not sure which one fixed it.  research has shown that if your ignitor is not glowing white it is ignitor.  My no light condition was accompanied by fain gas odor so I replaced valve too.  My  old ignitor was glowing yellow.  This gas valve has a thermal coupler inside that won't allow gas flow if ignitor not hot enough.
