Oven Temperature Sensor Replacement Cost
Everything burns or nothing cooks through, temps swing wildly, an oven thermometer reads 50°F off the dial, or the display throws F2/F3/F4-family codes. The thin probe on the back wall tells the control the temperature — when it drifts, everything drifts.
National averages for independent repair companies. Service-call/diagnostic fees ($75–$150) are usually applied toward the repair. Costs vary by brand, model, and city.
What causes it — and what each fix costs
Sensor resistance drifted
The RTD probe should read ~1080–1100 ohms at room temperature on most ovens; out of spec = replace. A two-screw, one-plug job.
Needs calibration, not parts
If it’s consistently 15–35°F off in one direction, most electronic ovens let you offset the calibration in the settings — free.
Repair or replace?
Repair — among the cheapest oven fixes. Buy a $10 oven thermometer first to confirm the problem is real.
We'll quote you on hauling it away — or buying it.
Not every oven & range is worth repairing, and we'd rather tell you that than sell you a repair. If you're replacing it, we'll give you a free quote either way: scrap pickup for a machine that's finished, or a cash offer if it still has life in it. Working units, recent models and premium brands are often worth real money.
Common questions
Why do my cookies burn on one rack and not another?
That’s airflow and rack position, not the sensor — hot spots are normal oven behavior. A sensor problem shifts the WHOLE oven’s temperature, not one rack.
