Gas burnersIgniter and Spark Module Faults
A burner that clicks and clicks after it lights, or one that never sparks at all, usually points to a wet or cracked igniter, a stuck valve switch, or a failing spark module. The tech checks each electrode gap and listens for which burner the module is firing.
- Igniter electrode and ceramic insulator inspection
- Valve switch and harness continuity test
- Spark module output check and replacement
Flame qualityWeak, Yellow or Lifting Flames
If the flame looks orange, ragged or jumps off the burner, something is off with air or gas delivery. The independent pro cleans the ports and orifice, confirms the cap sits flat, and measures manifold pressure against the spec on the tech sheet.
- Burner port and orifice cleaning
- Cap and head alignment on sealed burners
- Regulator and manifold pressure test
Electric coilCoil Elements, Receptacles and Switches
When a coil burner stays cold, the culprit is usually the element, the receptacle block it plugs into, or the infinite switch behind the knob. A scorched or melted receptacle has to be replaced along with its wiring terminals, or the new coil will fail too.
- Element resistance test
- Burner receptacle and terminal replacement
- Infinite switch diagnosis
Smooth-topRadiant Elements and Glass Tops
Glass ceramic cooktops hide radiant elements and a limiter under the surface. A zone that stays dark, a hot-surface light that never goes out, or a cracked or crazed top all need a pro, and a cracked top should not be used until it is replaced.
- Radiant element and limiter testing
- Hot-surface light and sensor checks
- Cracked or crazed glass top replacement
InductionInduction Cooktop Errors
Induction cooktops throw error codes when a pan is not magnetic, the cooling fan stalls, or the power board fails. The pro reads the code, tests cookware compatibility with a magnet, and checks the fan and board before any part goes in.
- Error code lookup and cookware check
- Cooling fan and airflow inspection
- Power or generator board diagnosis
Controls and fitKnobs, Valves, Conversions and Tip Safety
A knob that spins without turning the valve, a valve stem that sticks, or a move from natural gas to propane all land in this group. The tech can swap orifices for the new fuel, adjust the regulator, and fit an anti-tip bracket on slide-in and freestanding units.
- Knob and valve stem replacement
- Natural gas to LP orifice conversion
- Anti-tip bracket installation
