I am not sure if I am posting this in the right forum and right section of the forum, but here it goes! Last summer (2012) I purchased a Kitchen Aid range with a ceramic cooktop. Since then, Ive had nothing but problems with it. I managed to get the cooktop nearly destroyed with severe scratches from a cleaning product they gave me, and after months arguing that I didn't clean the cooktop with a diamond cup-wheel they admitted that I might have hit a faulty ceramic plate and they replaced it free of charge. Yay! That was last march. They sent a replacement cooktop but the installation fee wasn't covered. The appliance tech who brought it here sincerely admitted that the replacement was a 15 minute job and I could do it myself. Having nearly renovated an entire house alone, I agreed to replace it myself. I managed to pull the old one, carefully unplug the heater elements and brackets, and reinstalled the new cook-top. Fast forward 4 months to today, I have noticed something Ive never seen before (or didn't noticed but it happened?), that is, the ceramic glass becomes glowing red when the heater is at maximum capacity for 10 min+. Its not just the circular element underneath that glows red but the actual glass. The first picture below shows the element at 100% capacity and the second picture shown the glowing red spot on the glass with the element totally off (this last several seconds after I shut off the element). So my question: is it normal?!? Anyone else having noticed this? PS: Colors are WAY off so sorry ..
