Oven too hot or not hot enough? We calibrate and repair temperature sensors, boards, and elements. 90-day warranty. Average repair cost: $100–$300. Professional service recommended.
Sunnyvale's warm, dry climate at 84-90°F summer highs with minimal humidity creates conditions where oven temperature drift is primarily driven by age and usage rather than environmental factors. Eichler homes with poor insulation can experience kitchen temperature extremes that force the oven to cycle aggressively, but the dry air prevents sensor-damaging moisture. Premium appliances in tech-worker homes have precision sensors that detect smaller deviations and provide electronic calibration adjustments. San Jose Water at 250 ppm TDS deposits moderate minerals from cooking steam. Dust from the dry climate enters through convection vents and can accumulate near sensor probes, adding a thin insulating layer.
Sunnyvale's dry climate means temperature drift is age/usage-driven rather than environmental. Eichler home insulation affects oven cycling patterns. Premium appliances have precision sensors with electronic calibration. San Jose Water at 250 ppm TDS deposits moderate minerals. Dry climate dust accumulates near sensors. Twenty providers serve the market.
Faulty temperature sensor
Calibration drift
Failed control board
Damaged bake element
Door seal leak
Normal wear on internal parts is the leading cause of oven oven temperature wrong issues. Regular use over 5-10 years gradually degrades moving parts and seals.
Cost: $140–$270 | Time: 60-90 minutes
Control board malfunctions, faulty sensors, or wiring issues can cause oven temperature wrong symptoms. Power surges and age-related degradation are typical triggers.
Cost: $168–$320 | Time: 45-75 minutes
Debris, mineral deposits, or foreign objects can restrict normal operation. This is often preventable with regular maintenance.

This repair involves electrical components or sealed systems requiring professional tools and certification.
Temperature sensor repairs cost $100-$300. Sunnyvale's favorable climate means sensor lifespan is among the longest in the Bay Area. When drift occurs, it is typically age-related after 8-12 years. Electronic calibration adjustment on premium ranges may resolve small offsets without part replacement.
In Sunnyvale, wide day-night temperature swings (30f+ delta) stress thermal expansion joints, thermostat cycling, and sealed-system pressures. This can affect your appliance's door glass (inner panel): thermal shock from large temperature differentials between cold ambient air and oven heat can cause inner door glass to crack or shatter Avoid running self-clean when outdoor temperatures are below 40F; never spray cold water on hot glass
