Oven Failures in Cupertino: What Breaks and What It Costs
‍

Ovens are among the most heavily used appliances in any kitchen, and their failure profile differs significantly between gas and electric systems. In Cupertino homes, where professional-grade ranges from Wolf, Viking, and Thermador are common alongside standard electric and gas units, accurate diagnosis requires brand-specific expertise. Here’s what our technicians encounter most frequently:

‍

• Bake element failure (electric ovens) — the most common electric oven repair. The bottom element burns out, producing no heat on the bake cycle. Replacement: $100–$220 including parts and labor. Identifiable by visible burn marks or breaks in the element.

• Broil element failure (electric ovens) — similar to bake element failure, but affects broiling. Replacement: $90–$200.

• Gas igniter failure — the most common gas oven issue. The igniter glows but doesn’t ignite gas, or the oven takes more than 90 seconds to light. Replacement: $120–$250. Gas igniters weaken over time and must be replaced as OEM parts on premium brands.

• Gas valve failure — gas doesn’t flow even when the igniter is working. Replacement: $150–$320. Requires certified gas technician.

• Thermostat or temperature sensor failure — oven runs too hot, too cold, or can’t hold a set temperature. Replacement and recalibration: $100–$250. A common source of “uneven baking” complaints.

• Control board failure — error codes, unresponsive controls, or oven that won’t start. Replacement: $200–$450. On premium brands, control boards are proprietary and must be sourced as OEM.

The $90 service call covers a complete assessment of the heating system, ignition circuit, and temperature controls, with a written estimate before any work begins.

Gas Oven Safety: When to Call Immediately
‍

Gas ovens require the same safety awareness as gas stoves. Treat the following as same-day service situations:

‍

• Gas smell when the oven is off: Evacuate, ventilate, and call for service immediately. Do not use electrical switches.
• Oven that won’t reach temperature consistently with a slow or dim igniter glow: The igniter is failing and should be replaced before complete failure occurs.
• Yellow or orange flame inside the oven burner: Indicates incomplete combustion — can produce carbon monoxide. Requires immediate inspection.

Oven Calibration: A Commonly Overlooked Issue
‍

Many Cupertino homeowners assume their oven temperature is accurate because it reaches the set point — but oven thermostats drift over time. An oven that reads 350°F may actually run at 325°F or 375°F, which explains why baking results become inconsistent over the years.

‍

Appliance ProCare technicians use calibrated digital probes to verify actual oven temperature against set temperature on every oven service call. If calibration is off by more than 25°F, we adjust or replace the temperature sensor — this is included in the diagnostic at no extra charge.
