- Simmer burner adjustment and low-flame calibration
- Cast iron grate and burner cap inspection
- Full gas leak test and commissioning after repair
The Dacor Heritage rangetop is a statement piece — a wall-to-wall bank of professional open burners delivering up to 18,000 BTUs per burner on models like the HRTP486S. Unlike sealed-burner gas cooktops, the Heritage open-burner design allows technicians full access to every combustion component, but it also means that grease, debris, and heat cycling accumulate deep in the burner assembly in ways a sealed cooktop cannot. Our rangetop repair specialists understand this platform's unique maintenance requirements.
Common Dacor Rangetop Problems We Fix
- Burner not lighting from spark igniter
- Flame pattern uneven or lifting from burner crown
- Simmer burner unable to hold a low flame
- Continuous clicking after burner is lit
- Gas smell near manifold or valve body
- Grate supports cracked or burner cap corroded
Error Codes We Diagnose
Heritage rangetops are largely mechanical gas appliances without electronic fault displays, but ignition control modules on HRTP models can produce fault states that manifest as continuous spark, no-spark, or valve lockout. We diagnose these using manufacturer service documentation and gas-system pressure analysis rather than relying on a fault code readout.
Models We Service
- HRTP366S — 36-inch Heritage 6-burner rangetop
- HRTP486S — 48-inch Heritage 6-burner + griddle rangetop
- Legacy Dacor PGR and DR series open-burner rangetops
Open-Burner Expertise
Open-burner rangetops require a different approach to cleaning and calibration than sealed-burner models. We disassemble each burner to the orifice level, clean venturi tubes, inspect brass orifices for corrosion or blockage, and verify flame geometry against Dacor's specification drawings. Gas pressure is measured at the manifold and at each individual valve to confirm even delivery across all burner positions.
Transparent Pricing
Dacor rangetop repair starts from a flat diagnostic rate. Multi-burner cleaning and calibration packages are available. All estimates are fixed-price before work begins.
