Oven Temperature Inaccurate

Why an Oven Runs Hot or Cold

An oven that bakes unevenly or finishes food faster or slower than the set temperature usually has a problem with the temperature sensor, the probe that reports the cavity temperature to the control board throughout the cook cycle. A drifting sensor reports a temperature that is off by a consistent margin, so the oven runs hot or cold across every bake even though the display shows the correct set point. A miscalibrated thermostat produces a similar symptom on older mechanical-thermostat ovens, where the dial no longer matches the actual cavity temperature. Less often, the control board itself misreads a working sensor's signal, in which case the oven behaves erratically rather than consistently hot or cold, cycling unpredictably instead of holding a steady offset.

How San Marcos Appliance Repair Fixes It

A technician tests the temperature sensor's resistance against manufacturer specifications, checks thermostat calibration, and verifies the control board reads the sensor correctly before recommending a repair. San Marcos Appliance Repair carries common sensors and control boards for Whirlpool, GE, Samsung, LG, KitchenAid, Bosch, and Viking ovens and ranges, so most repairs are completed the same day. Every completed repair is backed by a 90-day parts-and-labor warranty, with same-day appointments available seven days a week across San Marcos and North San Diego County. Call 760-621-5157 to schedule same-day service.

Diagnosed by Certified Technicians

A technician evaluating the temperature sensor, thermostat, and control board on this repair holds NASTeC certification in appliance service and repair, trained through MiraCosta College's Technology Career Institute or San Diego College of Continuing Education (SDCCE) before joining the team led by founder and Master Appliance Repair Technician Francisco Ortega, who has run San Marcos Appliance Repair since 2006. That training is what backs the 90-day parts-and-labor warranty on every oven temperature inaccurate repair, backed by our licensed and insured guarantee.
