An oven that will not heat: the igniter on gas, the element on electric

A gas oven lights from a glow-bar igniter, not a spark. The igniter draws current, heats to orange, and that same current path opens the gas safety valve. As it ages, the igniter still glows but no longer pulls enough current to open the valve, so the oven sits there glowing and never lights. Replacing the igniter restores both the glow and the gas, which is why this is one of the most common gas oven repairs there is.

An electric oven uses bake and broil elements, resistive loads that fail open. A bake element that has cracked or blistered will read open on a meter, and the oven will preheat on broil only or not heat at all. The broil element often quits first because it runs hotter and cycles harder. Testing at the terminals tells you which element let go before anything is ordered.

Uneven baking, hot spots and temperature swings

An oven that burns the bottom of a sheet pan while the top stays pale usually has a calibration or airflow problem rather than a failing element. The oven temperature sensor, a resistance probe at the back of the cavity, drifts with age. When it reads high, the control shuts the element off early and the oven runs cool. When it reads low, the oven overshoots and scorches the rack above the element.

Convection models add a fan and a third element behind the baffle. A convection fan that has seized leaves the rear element heating one area of the cavity, which produces the hot spots you are seeing. If you have checked the oven against a separate thermometer and the average reading is far off, that is the point to have the sensor and the control tested rather than adjusting every recipe you own.

Control boards, relays and the faults that follow them

The control board is the switch for everything downstream. Elements and igniters are wired through relays on the board, and a relay that has pitted or welded closed holds a burner on or keeps an element off no matter what the keypad says. Error codes on the display usually come from the board's own self-check, so the code is a starting point rather than a verdict on the part it names.

Board-level testing means working at mains voltage inside a live appliance. That work belongs to a qualified technician with the right meter, and only with the oven isolated at the breaker. If you smell burning from the control area, can see scorched wiring, or the range trips a breaker when it starts, stop using the appliance and have it examined before the next meal, not after.

Cooktop burners that will not light or will not stay lit

A sealed gas burner that clicks but never lights is often a wet or dirty spark electrode, a burner cap sitting off center, or a spark module that has stopped sequencing. Cleaning and drying the electrode and reseating the cap resolves many of these calls. A burner that lights and then dies within a few seconds is a different problem, and it usually involves the flame sensing circuit or the gas valve.

Anything past the electrode and the cap is gas work. Burner valves, the manifold, the pressure regulator and the supply connection must be handled by a qualified technician, and nobody should open a gas appliance to service valves or attempt a repair on a gas leak. If you smell gas, leave the area, do not touch switches or the range, and call your gas utility from outside before calling anyone about a repair.

Self-clean faults and the door lock assembly

The self-clean cycle drives the cavity far hotter than any baking temperature, which is why the door locks and why so many failures show up during or right after a clean. The door latch motor and its switch fail from heat and baked-on grease, leaving the door locked with the display flashing or the oven refusing to start a normal bake afterward.

A long self-clean on a dirty oven can also take out the temperature sensor, the cooling blower, or the thermal fuse on the back of the cabinet. If the oven goes completely dead after a clean cycle, the fuse and the high-limit thermostat are the first parts to test, followed by the board. Running shorter clean cycles and wiping spills before they bake on cuts down how often this happens.

What happens on the service visit for your oven or range

The appliance diagnostic is $95, and it is credited in full toward the repair when you approve it with any repair you approve. We test the igniter current path, the elements, the sensor and the control under power, and we give you the fault, the part, and the price before any work begins. Most completed appliance repairs land between $145 and $295 depending on the part required.

Sealed-system work, built-in or panel-ready appliances, and multi-fault jobs are quoted separately after the diagnosis. Every completed repair carries a 90-day warranty. Gas valve, gas line and burner manifold work is performed by a qualified technician, and we will tell you plainly if a repair is not worth doing on an appliance of that age. Call (858) 267-9438 with the model number and the symptom.

High-end brand and cooling-system diagnostics are $145, also credited in full toward the repair when you approve it with any repair you approve.
