Douglas W Carmichael , CA October 28, 2016 Appliance: Model THERMADOR S301T I found a disintegrating piece of honey combed material on the floor of our oven after cleaning When I measured the honey-combed material and described it in a chat to AppliancePartsPros, I was told that it was a disintegrating catalyst. I ordered the part for abouit $25 including shipping. It arrived promptly. I replaced the catalyst with a screwdriver. The total job took less than 5 minutes. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
