Kingman for Model Number Maytag MGR5745ADA Helping a friend fix her oven. Doesn't heat reliably. She smelled gas. I saw ignitor glow, but it had a hot spot in middle and rest of ignitor glowed only orange. Gas took from 2 to over 4 minutes to come on. When gas came on, burner lit with strong flame then after seconds went to low flame. I assume ignitor is bad and this is confirmed by your forum answers. I have a MSEE degree and have a couple of questions if you'd indulge me for my curiosity (the more technical the answer the better!). I'd like to understand exactly how this system works.: 1) Does the current through the ignitor open the gas valve? 2) Does the gas valve automatically have a high/low sequence when energized or does the current through ignitor control the size of the flame? Thanks!!
Answer Hello Kingman. Yes, currect opens the valve and based on the infor you provided, you have a weak igniter and it needs to be replaced. Read More... Answered by AppliancePartsPros.com | Wednesday, January 30, 2013
