Skcincy for Model Number WFG540H0ES0 Tenant complained that oven would not always light. I removed bottom pan to watch ignition process and it worked fine about 10X. Valve clicks open, spark igniter sparks (two rapid sparks, repeated if not immediately ignited) and burner lights up as expected. Reassembled and started a few more times before I could duplicate failure to light. In this case the spark igniter clicks 8X (four pairs of rapid clicks) and then stops, locking control. I can CANCEL and unlock START control and get it to start but I have more patience than my tenants. Also, there is a bit of residual gas in the oven when it fails to start. I think gas valve shuts off when control is locked but the gas resulting from failed ignition does cause a little concern. Note that I could only duplicate the problem when the burner was already a bit warm. I wonder if the gas is being heated to a point below the ignition temp but rising above the igniter and not lighting right away. Normally the natural gas will be a bit heavier than air and fall slightly as it comes out of the burner. Any suggestions? All parts seem to be doing their job.
Answer Hello SKCincy. I would check and make sure the burner is clean and not rust and make sure the orifice is clean. In this case, it sounds like one of the 2 may be dirty. Read More... Answered by AppliancePartsPros.com | Wednesday, February 22, 2017
