Well I actually wanted a professional to fix it... I ordered the parts and scheduled the upgrade, but the local repairman cancelled my appointment. So I watched a few videos online and did it myself. Wasn't as bad as I thought it would be. But you really need to be careful you don't drop the orifice when your putting in the new ones. On my stove it would have been a real pain to retrieve. Luckily I made it through without issue. And have to hand it to Appliance Parts Pros, 2 day delivery just as estimated.
