Matthew B Danville , PA January 05, 2015 My gas range had a mouse nest inside in removing the cooktop i pinched the gas tubes that feed the two front burners The left two and right two burners come as an assembly each. I ordered the replacement assemblies, "orifice tubes" and replaced my pinched ones with the new. The only issue I ran into was my stove runs on LP Gas and the orifices in the new assemblies were for Natural Gas. No matter, I just removed the four orifices that came with the new assemblies and replaced with the four orifices from my unit. The entire job took just over an hour. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
