Pete for Model Number SF362LXTS0 We've been having an issue with the gas oven not lighting - gas would flow, you could hear the igniter clicking, but the gas would not ignite. Removing the floor of the oven, I could see that there wasn't any spark. The range top worked fine as did the broiler. The problem was intermittent and rare but suddenly got much worse. I replaced the igniter (part no. 9758079) and everything worked fine for about 2 weeks. Now, the oven almost never lights (broiler and range still okay). At this point, after doing some more reading, I believe the problem is a) a bad ground, b) a bad spark module (part no. W10331686), or c) a faulty control board. My question is how do I determine which is the likely culprit? I'm comfortable using a mutlimeter but am not sure where inside the oven I should attaching the leads to verify the ground for the igniter or to check the floating voltage. And I haven't yet found a guide on how to test the spark module. Any guidance would be greatly appreciated.
Answer Pete, You will need to check the resistance of the gas valve coils WPW10293048, the DC voltage at the valve from the DSI module WPW10331686 and check the oven burner tube for dirty or clogged ports. You'll need to get access to a multi meter TJMA-DM1 to test the circuits and voltages. Here's the test information; "First thing, check and make sure the power cord is attached to a properly polarized and grounded 120 VAC outlet. A proper ground is very important for the range to operate properly. Then you'll need to make several tests at the gas distribution valve. At the valve body terminals, with the wires labeled and remove from the middle terminal to each of the outer terminals, you should read 215 ohms resistance. With the wires reconnected, when you select the bake cycle, you should have a reading of 8 to 18 VDC across the red and orange wires. When you make a broil selection you should have the same 8 to 18 VDC,across the orange and blue wires. If all checks are proper(within 10%) replace the oven bake burner and or igniter." Read More...
