Igniter comes on for 2 minutes. Then gas comes on for 20 seconds, then gas goes off. Igniter stays on. Oven does not get very warm at this rate.
Answer Hello Gary. Test for 3.2-3.6 volts AC at the gas safety valve with the igniter turned on. If the voltage is there, you have a bad safety valve. If the voltage is low, you have a weak igniter and the igniter will need to be replaced. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
I turn oven on, igniter soon glows, no sound of gas and hence no lighting of main burner. Display confirms my request to light the oven burner.
Answer Bob, You most likely have a weak oven igniter 786324 based on your post. The igniter has to have a 3.2 to 3.6 amp draw, or produce 3.2 to 3.6 VAC to the wires on the safety valve, in order to open the bi metal switch and release the gas for ignition. The igniter can glow, but not draw or produce the amps and volts to open the gas valve. Thanks and Good Luck
My dual gas valve keeps failing. I measured the power going to the valve and it was 120 VAC. It says right on the valve not to apply 120 VAC to the valve. What could be shorted out allowing 120 VAC to be powering the valve?
Answer Hi Nick. You are correct,you should not be getting 120vac to the gas valve. Is there a pinched wire at your transformer that is shorted,sending the wrong voltage. The power cord can be frayed or shorting. Check all wires as varmit love to chew. The gas valve part # is Y0306429. Consider a fresh igniter also part # is 786324. Is the wires going to either the spark module or the burner switches pinched or shorting? Hope this helps. Thank you.
