The tech came within a few hours of calling, but couldnt get parts for our 9 year-old GE Monogram oven through his Canadian supplier list. He did provide me the required p/n and identified that it was available on Amazon with a 2-3 week lead time.
I found several websites in Canada to obtain the part within 2-3 weeks, as the required circuit board comes from GE in the USA. The Express Appliance office wouldnt order from any of them, and wouldnt extend the 7 day limit to complete the repair without a second $99.95 service fee. When the parts arrive, I will either install it install myself or find another company.
