Question: Can someone please explain the point of a drip pan that has a hole in the middle for things to drop through it?  My drip pans don't have holes.
Document: Trying to decide what to buy was quite confusing until I read the January 31, 2014 review by Erin Fesperman for the Range Kleen P119204X black porcelain drip pan 4 set. She has posted images showing the diameters of both the 6&#34; and 8&#34; pans of this set and the diameters of the range top holes required for them. When I compared those dimensions with my original chrome drip pans and my range top holes I was convinced that the P119204X pans would fit perfectly.
I bought these to replace my existing drip pans because the 8 inch sized one doesn't sit properly in the hole. It sits above and wobbles around, also overlapping the 6 inch drip pan located behind it on the stove. These do the same thing. They are listed as being for my specific stove, so I'm not sure why the 8 inch is always too big, but in any regard I paid to get the same issue. At least they're easy to clean and don't show as much drip and grease.
I have a Ropers (Sears?) self cleaning range. The small ones fit so long as you insert the element first. The large holes on my range have 3 &#34;flat spots&#34; that protrude into the hole that prevents me using the large ones. Make sure you check for that feature!
My husband is a messy cook and never cleans drip pan so stuff get burnt on. These drip pans clean easy and do not show the scorched messes
The drip pans were delivered timely and packaged well. If these are the size you require to replace existing pan, I would highly recommend this product. I will buy again in the future as needed.
These drip pans are awesome! I definitely like them over the traditional silver pans. They are a little bit heavier than the silver ones and are easy to clean. The holes in my stove measure approx 8.5&#34; for the larger ones and 6.5&#34; for the smaller ones. I will include some pics to help everyone out. Sorry if the ruler looks off, it is the way I was holding the camera.
The process of finding black porcelain replacements for the chrome drip pans, WB31t10010 and WB31T10011, that came with my range proved to be a bit more difficult than I would have imagined. On the GE website I could not find black porcelain options for ranges that use those drip pans. And, the black porcelain options available from many different suppliers do not clearly state that their options will replace the pan part numbers shown above.
I would be completely satisfied with this product, except that it doesn't fit my kenmore...and it turns out that range-kleen is the only drip pan that Sears sells too...The porcelain is very very easy to clean, and very convenient...I love it , but can't use it...
I like the Porcelain drip pan, it would be easier to clean and last longer than the chrome ones, but my stove is beige color, so the black color doesn't really match the stove. I hope this product will come in more colors in the future?
Maybe I got lucky on the first try? They are also very easy to clean off as I am a messy cooker and spil, about 3/4 of what ever I'm cooking all over the place, the clean up was important to me. Hope you enjoy this drip pan set as much as I am.
Answer: It is so that if food boils over, and there's a lot of it, it won't fill up the drip pan, touch the element, and smoke or catch fire.
