Customer Questions and Answers for Surface Burner Grate Kit (Black) by Whirlpool

Flavia, No, There are not "another grate model compatible with this range". The grates are available in different colors(black or gray) but the configuration and height are the same. The height and configuration of the cooktop grates are determined by the design and engineering teams at the manufacturers facility for safety and proper operation, before the range is even produced. You may want to re check the owners manual for specialty cooking information and make sure the range has the proper gas supply and is installed properly( on some gas products, when the product is converted to LP Gas, the BTU ratings have to be lowered for flame safety and the pressure differences. In some cases it will take a few minutes more to produce the amount of heat needed to produce the desired results).
