Maestro for Model Number WFG520S0AS1 When we first turn oven on and set the temp, the oven clicks, sparks, gas flows, and ignites. Never an issue on first light. It reaches temp, then shuts off. However, it struggles to relight once temp drops. (I also think the internal temp drops WAY too low before it attempts to reignite but I don’t know if that’s normal). It will sense the temp drop eventually, igniter clicks, sometimes three times, then stop. It doesn’t always do this though; sometimes it lights on first try but it’s rare. If it fails after three clicks it makes another attempt a short time later. Sometimes it lights sometimes it doesn’t. A third scenario is the oven clicks, lights, but then it sounds like it blew itself out. It then tries again to light, sometimes lighting and sometimes not lighting. Finally there are times when it tries three times unsuccessfully and then just goes into protect mode I believe. In those cases I hit cancel and I start over. I believe I always I can hear gas flowing but it’s possible there are times when it doesn’t. A repair tech replaced wire harness while under warranty but I'm not sure what is causing these issues to still occur. .
Answer Maestro, Based on the information provided this issue sounds likely that the gas valve is possibly weak and causing this issue. Sounds like the solenoids inside the valve are breaking down once they get heated up. Read More... Answered by AppliancePartsPros.com | Tuesday, August 28, 2018
Answer Maestro, The igniter has to draw a certain amperage to open gas valve.Usually 3.2 to 3.5.If not order WP9758079.You can purchase a watt meter and plug your stove into the meter and set for amperage to check.Or clamp on meter whatever is easier.
