Product review (5 stars): Only ones that Fit Hotpoint
Hotpoint has made it so that you can not go into Lowe's or Home Depot and get the proper size Drip Pans.  You have to order online the Hotpoint Brand.

We tried every single size from Home Depot, Lowe's and Ace before finally giving up and buying Hotpoint Brand Drip Pans.  They were not expensive and the size is perfect.
