Danna I have a GE ZGU385LSMSS gas stovetop. None of the burners will light with the igniter. I am currently having to light all the burners with a match. Do I need to replace the Spark Ignition Switch and Harness or the Spark Module? Is there a way I can test each of these to see which one is not working? Thank you for your help.
Answer Danna, with the power disconnected and the gas turned off, you will want to test the switches WB18X23942 first. To do this, you will want to access the manifold section of the cooktop, turn on each burner separately and check for 0 resistance between the red wire on the transformer wire harness and the corresponding switch terminal on the spark module wire harness. The switch terminals are as follows: Center burner (Transformer Red to Module SW5/Gray), left rear burner (Transformer Red to Module SW3/Orange), left front burner (Transformer Red to Module SW2/Yellow), right rear burner (Transformer Red to Module SW4/Brown), right front burner (Transformer Red to Module SW1/Blue). From there you will want to test the transformer WB27X21609 by checking the primary winding for approximate resistance value of 32.8 ? between the 2 brown (input) wires. Then check the secondary windings for approximate resistance value between: White to red - 2.2 ?, Brown to red - 196 ?, Brown to white - 198.2 ?. If these tests pass, then you will want to replace the spark module WB13T10076. Read More... Answered by AppliancePartsPros.com | Thursday, April 4, 2019
