My wife and I were doing a kiln firing that got interrupted because the thermocouple failed on three of the six burners. We reported it early on 6/30/17. Ray was sent almost immediately to fix it on 6/30/17. Very professional work with thorough explanation of why the thermocouple failed and quick repair. When more work is needed, Kim and Ray will be the first folks we will call. Michelle sorted us through various phone calls that got the process rolling.
