Your kitchen back to full function — gas and electric ovens repaired
Oven not heating to temperature or burners that won't ignite
An oven that preheats sluggishly or can't hold 350°F usually has a weakening igniter (gas) or a burned-out bake element (electric). A weak gas igniter draws too little current to open the gas valve fully, so the oven heats slowly and runs cool. San Jose homeowners often think the thermostat needs recalibration when the igniter is actually the problem. We measure igniter draw and replace the correct component — a repair that takes under an hour in most cases.
A burner that clicks repeatedly without lighting usually has food debris blocking the igniter cap or a cracked igniter electrode. On Samsung and LG gas ranges — popular in Palo Alto and Saratoga kitchens — a faulty igniter module can cause all burners to spark simultaneously. We clean and test each burner individually and replace the spark module or individual igniter as needed, so you get reliable ignition every time.
An F3 or F9 error on your GE, Whirlpool, or KitchenAid oven usually points to a failed temperature sensor or a runaway relay on the control board. Before replacing the board — which can cost $200–400 — we verify whether the sensor is the actual failure. In most cases we've seen in Los Altos and Menlo Park homes, the temperature sensor is the part, and it's a $40–80 fix.
Running the self-clean cycle at high temperatures can trip the thermal fuse or damage the door latch motor, leaving the oven locked with no display. This is one of the most common oven calls we get in San Jose — and one of the most misunderstood. Replacing just the blown fuse restores full operation in most cases. We carry thermal fuses for common GE, Whirlpool, and Samsung ovens and complete this repair same day or next day.
