How to Troubleshoot & Replace Ge AP2027954 / WB31K10027 Gas Burner Grate

I have been shopping around to buy new grates to replace our old ones. We have GE gas range. So I checked on GE for part replacement. I got information of ApplicancePartsPros on internet. The price from ApplicancePartsPro are better than GE. I have a next day delivery at reasonable cost. Thanks to ApplicancePartsPros. Now I have a nice looking range. 

Ordered new ones online after researching several companies and decided to order from AppliancePartsPros. This has been the best experience we have had with dealing with a company online. They were always available to answer questions and their delivery time was excellent. I would certainly return to them in the future. Marilyn & John
