Replace the plug - 3 prong proper.(get the cool 90* plug) Then plug unit into a GFCI protected outlet. If it trips the GFCI you have an issue with oven. If it doesn't trip and everything works - "I" would consider it good.quote:Originally posted by Jett:Would the missing ground prong on the plug be enough to cause this issue, or is there something else goin on. I was planning on replacing the plug, but wanted to ask advise first.
